苹果手机刷机了高手还能把以前的东西找回来啊
我有更好的答案
苹果手机刷机怎么找回以前的数据，步骤如下：将手机用数据线连接电脑，打开手机【设置】，然后选择【系统】下面的【开发人员选项】，点击选择【USB调试】选项，这样计算机就会多出两个盘符，其中的‘I’就是手机ROM内存。2.运行数据恢复软件Easyrecovery，单击主界面下的【数据恢复】菜单，选择【高级恢复】选项，打开【高级恢复】界面。接着，依次单击驱动器列表下的“我的电脑一Linux(1.05GB)&（图2)，找到&I”盘（即手机的ROM内存卡）。3.选择【高级选项】，出现【高级选项】页面。如图选择【高级扫描】（图3)，确认后即可进行扫描操作。把扫描到的文件保存到本地磁盘下，这里就有手机系统以前删除的数据，用搜索功能即可搜索所需的文件。一般情况下都能恢复大部分数据，但是数据无价，手机刷机之前最好先备份数据。

一般情况下，我们是通过让苹果 iPhone 手机进入恢复模式，然后再利用 iTunes 来刷机。请先长按 iPhone 手机顶部电源键，待出来关机选项后滑动关机。关机以后，接下来就可以开始进入恢复模式的操作步骤了：一、按电源键开机，屏幕会出现苹果标志，不要松开电源键；二、接着再按住主屏 Home 键，直到屏幕黑屏；三、当屏幕黑屏时，请松开电源键，继续按住主屏 Home 键不要松开，直到电脑端的 iTunes 出现检测到一个处于恢复模式的 iPhone；注：如果没有进入恢复模式，正常开机了，请多尝试几次。要为苹果 iPhone 手机刷机的话，需要恢复文件。这个文件可以是自己手动下载，也可以让 iTunes 自己下载。二种方法都可以刷机，自己手动下载的速度可能要比 iTunes 下载要快一些。另外如果是自己手动下载，对于不熟悉的朋友，可能会下载错固件，导致刷机不成功。这里先介绍下让 iTunes 自动下载固件并为 iPhone 恢复的操作方法。在 iTunes 窗口中，点击“恢复 iPhone”按钮，随后 iTunes 会连网检测适合当前手机的最新的固件系统，并提示我们是否要删除所有数据并恢复，点击“恢复”按钮即可开始，接下来就请耐心等待 iTunes 下载固件，并把固件系统刷到苹果 iPhone 手机上。

不能，苹果是不能的，如果你刷机以后但，如果你重新登陆你的id密码，那么以前你手机的信息，可以出现在任何一个你的苹果设备上，这就是苹果比安卓安全又快捷的地方。
不可以恢复 如果有重要资料恢复的话 几千块钱吧

互联网 & 04-30 09:22:43 & 作者：佚名 &
激活锁这个功能呢好处就在于如果你的iPhone丢了你可以锁定手机远程清除数据，目前破解iPhone ID锁的方法大概两种，今天就来演示一下如何硬解ID锁。希望会对大家有所帮助的吧
　　iPhone5s忘记锁屏密码怎么办？激活锁这个功能呢好处就在于如果你的iPhone丢了你可以锁定手机远程清除数据，就算别人偷去了刷机了也只能是块砖头，但是也是一把双刃剑，有时候忘了密码也会,造成自己手机不能使用；目前破解iPhone ID锁的方法大概两种，一种就是带上购买时的正规机打发票和手机包装去苹果公司申请解锁，另一种是通过更换芯片来硬解锁。今天就来演示一下如何硬解ID锁。希望会对大家有所帮助的吧
　　iCloud账号是绑定在手机串号和序列号上的上的，当你手机上登陆iCloud时查找我的iPhone会自动打开，然后苹果服务器记录你这台手机的串号（IMEI）和序列号（SN）并和所登陆的iCloud账号绑定，等下次激活时就必须要之前的账号才可以激活，苹果 的激活策略是当你这台手机的IMEI和序列号匹配的时候才能激活，所以就是硬解就是要把这台手机的IMEI和相匹配的序列号改变，然后我们来看下图
　　从左到右分别是硬盘也就是16G的存储器（存储手机序列号），第二个是基带芯片，第三个是码片，（基带芯片和码片是一套的基带配合码片里存储的IMEI才能正常工作）所以理论上来说更换这个三个芯片就好了，但是由于目前5s码片数据读写已经被大神们攻破了，所以换的时候换基带和硬盘就好了，码片数据用专业编程器写进去就好了。然后们看看这三个芯片在主板上的位置
　　首先把硬盘用热风*把硬盘拆下来，
　　然后把主板上的焊盘处理好，
　　再把基带芯片拆下来，
同样处理好基带的焊盘
　　然后把新的码片数据导入原来的ID板
　　接着把新的硬盘和基带装上再刷个机
　　就可以开机激活证正常使用了
　　至此解ID锁就完成了。友情提示没有专业工具和手工基础不要轻易尝试以上内容，否则你的手机报废了没人负责哦！&

最近更新的内容苹果手机刷机以后必须用以前的id吗_百度知道
苹果手机刷机以后必须用以前的id吗
我有更好的答案
是的，因为苹果是用序列号和账号绑定的，刷机以后序列号不会变，账号自然是原来的账号。1、iphone关机状态，使用数据线连接电脑，打开电脑的iTunes软件。2、按住Power键2秒。3、在不放开Power键的状态下，按Home 键10秒，强制关机。4、不放开Home键，轻按Power键1次。保持不放开Home键15秒左右，手机屏显示连接Itunes 图标信息，进入DFU模式。5、电脑有声音和文字信息提示发现新硬件，并且iTunes提示有需要恢复的iphone。点击恢复，itunes自动下载最新的固件进行更新刷机。
不可避免的加~34┄8﹄995﹄12_ˇ┱╝由iPhone系列需要更换硬盘和基带套件。果随IOS7系统推出了ID锁功能，是出于保护苹果用户。这项功能在打开“查找我的iPhone”后激被触发。不明其工作原理的用户若随随便便越狱、刷机都会被ID锁锁住。但苹果公司推出ID锁功能没有在锁住手机前给出相应提示，不少苹果手机因此遭锁。不少用户遭遇ID锁后到官网找到关于ios7的ID锁功能解释，但为时已晚。这里头大多是二手苹果买家，却也有不少一手买家。不少一手购买者在专卖店购买苹果手机，是由商家用他们的ID激活的，一手购买者回去刷机后就被ID锁锁上。二手苹果买家多不明就里，有的甚至购买了三手、四手的机子，要找到最初ID激活者比上青天还难。而非国行手机的ID账号所有者更是无处找寻。要解开ID锁，目前比较靠谱的方法是让苹果激活ID锁小组关闭ID锁。用户申请解锁后，会收到苹果团队发来的邮件提示，要求提供原始发票、商家信息及产品信息等。苹果的邮件回复时间从2天到十几天不等，用户在申请了解锁要求后，唯一能做的就是等。而能拿出符合苹果公司要求的材料证明，只有部分国行手机的用户。其他二手的机子一律算作不正规渠道的手机，都无法解锁。

我们会通过消息、邮箱等方式尽快将举报结果通知您。明天又要刷机器了，装机工很久没玩，快忘光了，温习一下，O(∩_∩)O哈哈~
1，刷机前先检查和保留当前系统关键部件的信息，例如：
/opt/oracle.SupportTools/CheckHWnFWProfile -s
/opt/oracle.SupportTools/CheckHWnFWProfile -c loose
/opt/oracle.SupportTools/CheckSWProfile.sh -I dm01sw-ib2,dm01sw-ib3
imagehistory
2，跟NOTES 的内容，找到相关的image，download后，解压，例如：
unzip ImageMaker.tar.zip
tar -pxvf ImageMaker.tar
DB的image解tar后，可以发现 dl360 目录
CELL的image解tar后，可以发现 dl180 目录
这是因为，Exadata早先跟HP合作推出的V1，用的都是HP的pcserver系列，计算节点的型号是 dl360，存储节点的型号是 dl180，后来也就一直都没有更改了。
我们有四种方式刷机：
1. 用U盘刷机，也就是 USB flash thumb drive
2. 制作ISO image，使用ILOM指定iso的方式（当然如果刻录成光盘，也可以使用DVD模式）
3. 制作一个紧急启动的iso文件（类似于紧急启动盘），然后把image放在NFS上，进行刷机
4. 使用PXE+NFS
上面的4种方法，对于1/4配置来说，哪个都不复杂，用U盘和ISO Image最简单，也最省心。
对于满配或者大量的reimage工作来说，显然U盘就太不可取了，会累死人的，可以使用PXE+NFS和ISO image。
无论哪种方式，制作Reimage的命令都是一个makeImageMedia.sh，语法如下：
./makeImageMedia.sh
[-preconf &prconf.csv file full pathname&]
&dvd iso file name&
| [-pxe [-pxeout &pxe output filename& ]]
| [&nfs iso filename& -nfs nfs_share -dir nfs_dir [-nfs_ip &ip addr for nfs server&]
[-logpath &[lognfs_ip:]/full path to writeable nfs share&]
Exadata出厂时带有双操作系统，一个是Linux，一个是solaris x86，通常，至少国内的客户绝大部分都会选择使用Linux，因此，在安装完成后，我们需要做reclaim操作。
如果是Reimage，那么我们也可以在制作U盘，image或者使用PXE时带上 -dualboot=no 选项，这样就节省了后面刷机后的reclaim的时间（reclaim我印象中都要1小时以上）
Exadata出厂时带有缺省IP，这些信息在随机附带的document中可以找到。
在文档中，给出了Exadata出厂时的所有缺省IP，你可以看到，IP的分布是对应到物理机器的（当然，X4没有最下面的一个Spine switch了，级联的时候，如果需要可以单独购买）。
比如如果你是1/4 Rack的，那么可以根据每个部件的位置，确定其管理IP或者ILOM IP等等。
刷机时可以附带上新的IP配置文件， 这样就可以刷机后直接使用全套新的你指定的IP。当然如果不带的话，刷完了，机器所有IP就是文档中的缺省IP的配置了。
例如下面的过程制作了一个U盘，我使用了预先配置的preconf.csv文件来制定新的IP：
1，使用U盘启动的方式

之后使用这个USB启动服务器，启动后确认重新两次（它会提示你的，怕你误操作，O(∩_∩)O哈哈~），之后就没你什么事情了，他自己就work了……
之间会重启几次，最后一次，会提示你拔出U盘，然后，重启一下，就ok了。
2，使用ISO image的方式
由于ILOM提供了远程映射ISO文件的重定向功能，因此，我们可以启动ILOM，选择使用CD-ROM image的方式，然后使用ILOM执行reset来重启
如果是X2，那么就可以去喝茶了，如果是X3，那么还要等启动时在Bios中确认使用CDROM方式启动，然后再去喝茶……
如果ISO image的方式，无论是否有 -dualboot=no 选项，重装完的计算节点上都不再是dualboot，可以使用 reclaimdisks.sh -check 进行确认，使用ISO方法如下：
[root@lunar dl360]# ./makeImageMedia.sh -preconf ../preconf_db.csv -stit -notests diskgroup -nodisktests db_img112330.iso
Done. Pre config verification OK

使用ISO image的方式，不用拔U盘，O(∩_∩)O哈哈~，他自己重启几次（大概2~3次，忘记了），然后出现“Installation SUCCESSFUL”就ok了。
3,使用ISO image + NFS 方式
这个我没有尝试，但是根据readme，我看大约是制作了iso文件放在子目录中，当然，这个目录是放在NFS上的：
makeImageMedia.sh x.iso -nfs /exports/images -dir dl180/11132
readme上有详细的步骤，具体可以参考readme来完成。
4，使用PXE+NFS的方式
（1）首先要确认TITP功能，如果没有需要安装syslinux
yum install syslinux
（2）制作image
./makeImageMedia.sh -pxe
检查image文件：
cd /tftpboot/linux-install/dl360/PXE
-rw-r--r-- 1 root root
Aug 19 10:39 initrd-11.2.3.2.1-130109-DL360.img
-rw-r--r-- 1 root root
Aug 19 10:39 nfsimg-11.2.3.2.1-130109-DL360.tar
-rw-r--r-- 1 root root 69 Aug 19 10:39 nfsimg-11.2.3.2.1-130109-DL360.tar.md5
-r-xr-xr-x 1 root root 3688864 Aug 19 10:39 vmlinux-11.2.3.2.1-130109-DL360
cd /tftpboot/linux-install
drwxrwxr-x 7 root root 4096 Aug 19 10:39 dl360
-rw-r--r-- 1 root root
Aug 19 10:39 initrd-11.2.3.2.1-130109-DL360.img
drwxr-xr-x 2 root root 4096 Aug 16 2012 msgs
-rw-r--r-- 1 root root
Aug 19 10:39 nfsimg-11.2.3.2.1-130109-DL360.tar
-rw-r--r-- 1 root root 69 Aug 19 10:39 nfsimg-11.2.3.2.1-130109-DL360.tar.md5
-rw-rw-r-- 1 root root 13100 Jul 25 2011 pxelinux.0
drwxr-xr-x 2 root root 4096 Aug 19 09:15 pxelinux.cfg
-r-xr-xr-x 1 root root 3688864 Aug 19 10:39 vmlinux-11.2.3.2.1-130109-DL360
（3）配置NFS Exports，并启动nfs server
cat /etc/exports
service nfs restart
（4）安装 TFTP SERVER
yum install tftp-server
chkconfig --level 345 tftp on
（5）修改 TFTP 配置文件：
/tftpboot/linux-install/pxelinux.cfg/default
注意，其中的 kernel vmlinux-11.2.3.2.1-130109-DL360 就是上面我们生成的
（6）配置DHCP
yum install dhcp
mv /etc/dhcpd.conf /etc/dhcpd.orig
chkconfig --level 345 dhcpd on
检查 /etc/dhcpd.conf，例如：
option ip- # No IP forwarding
option mask- # Don't respond to ICMP Mask req
subnet 10.187.114.0 netmask 255.255.254.0 {
option routers 10.187.114.1;
next-server 10.187.115.250;
######这个是PXE SERVER
filename &linux-install/pxelinux.0&;
option root-path &10.187.115.250:/tftpboot/linux-install&;
host exadbmel02 {
hardware ethernet 00:21:28:A3:27:68;
######eth0的MAC地址
fixed-address 10.187.115.225;
######这个是需要做reimage的节点的eth0
这里确认eth0的信息，也可以通过ILOM的方式： System Information -> Components -> /SYS/MB/NET0
或者ssh到ILOM，执行： show /SYS/MB/NET0
（7）重启一下所有网络相关服务：
service dhcpd restart
service xinetd restart
service iptables stop
这样配置好了PXE，就可以使用PXE+NFS了，后面的过程类似于ISO image了。
上述4中reimage的方法和详细步骤，参见readme：

================================================================
Imaging install media options and imaging procedures for Exadata
================================================================
DO EVERYTHING AS root USER
|-------------------------------------------------------------------------|
FOR SUN Factory the process involves 2 rounds of PXE+NFS imaging |
Scroll all the way to the end of the document to see the overall |
steps in the process and sample pxe configuration files.
|-------------------------------------------------------------------------|
Creation of the installation USB or ISO:
Download the production ImageMaker.tar.zip files on some machine
with Oracle Enterprise Linux 64bit or RHEL 64 bit that has
grub 0.97 and has tar with bzip2 support
- grub --version will show the grub version
As root user extract the ImageMaker.tar.zip file
unzip ImageMaker.tar.zip
tar -pxvf ImageMaker.tar
Cell node image extracts to dl180
DB node image extracts to dl360
The makeImageMedia.sh script inside the above directories is used to
create the actual image installation media.
The installation media can be
1. USB flash thumb drive
2. ISO image that may be used on DVD or as remote virtual media using
LightsOut remote virtual media capabilities.
3. ISO+NFS - where a small iso file is used to boot the system and the
imaging payload is hosted on a NFS server.
4. PXE+NFS
---------------------------------------------------------------------
| Run all commands AS root from inside the dl180 or dl360 directory |
---------------------------------------------------------------------
./makeImageMedia.sh
[-preconf &prconf.csv file full pathname&]
&dvd iso file name&
| [-pxe [-pxeout &pxe output filename& ]]
| [&nfs iso filename& -nfs nfs_share -dir nfs_dir [-nfs_ip &ip addr for nfs server&]
[-logpath &[lognfs_ip:]/full path to writeable nfs share&]
Install media preparation
-------------------------
USB thumb drive - also known as the CELLINSTALL USB
---------------------------------------------------
NOTE: It is best to have no other external USB storage
devices connected to the machine on which you
prepare the installer USB s.
Insert empty USB thumb drives of size between 2GB and 32GB,
and follow prompts after executing:
./makeImageMedia.sh
ISO - That may be burnt on DVD and used for install
---------------------------------------------------
./makeImageMedia.sh &iso file name&
Example: ./makeImageMedia cell.iso
nfs iso is either created on the nfs server itself where the
nfs export path is nfs_share e.g. /exports/images and nfs_dir is the
subdirectory of nfs_share where image bits are copied by the iso creation
command e.g. dl180/11132.
The iso may be created anywhere using the nfsip option to supply the
ip address of the nfs server and then the contents of nfs_share directory
must be copied to nfs server at the EXACT same path as nfs_share
NOTE: nfs iso MUST either be built on the nfs server as root user
you must supply the ip address for nfs server with -nfsip
nfs iso built on the nfs server:
makeImageMedia.sh x.iso -nfs /exports/images -dir dl180/11132
Will create x.iso and copy image bits to /exports/images/dl180/11132
You can copy the preconf.csv file then to /exports/images/dl180/11132
You can of course embed the preconf.csv file in the iso itself with
makeImageMedia.sh x.iso -nfs /exports/images -dir dl180/11132 \
-preconf preconf.csv
nfs iso NOT built on nfs server:
makeImageMedia.sh x.iso -nfsip 123.123.123.123 -nfs /exports/images \
-dir dl180/11132
Will create x.iso and copy image bits to /exports/images/dl180/11132
You can copy the preconf.csv file then to /exports/images/dl180/11132
You must now copy the entire contents of /exports/images/dl180/11132
onto the real nfs server 123.123.123.123 exactly at path
/exports/images/dl180/11132 and the nfs server must export
/exports/images
-logpath option now may be passed to makeImageMedia.sh to extract the logs
from imaging and zero and first boot validations. See the logpath option
syntax in PXE support
-dhcp option now may be passed to makeImageMedia.sh to use dhcp to get
initial ip address during imaging.
-multiprof option will create multiprofile images
Optional command line options for USB / ISO / NFS+ISO installation media
--------------------------------------------------------------------------
print special [FACTORY_...] messages for use by factory.
-kerver &kernel_version&
overwrite default kernel. By defaut installing kernel version depends
on hardware type (system product name). List of kernels and hardware
dependencies defined in the &kernel_ver& line at the very top of
makeImageMedia.sh script.
-dualboot &yes|no&
overwtire default dual boot behaviour. It's only applicable for the
db node. By default dual boot feature (installing Linux image and
prereserving space for Solaris) depends on hardware type (system
product name). By default X4170 M2 and X4800 (G5) servers have dual
signals to force reimage even if installation exists on the machine
-reboot-on-success
Do not wait for operator to power off machine on successful image,
just reboot. Useful for mass unattended imaging using preconf option.
DO NOT use in factory process.
-nodisktests
do not run disktests at zero boot. They take 6-14 hours!
-notests &group for validations to be skipped, e.g. diskgroup&
skips all validations with given vldgroup name. For example, if
diskgroup is given as the group name, then each validation with
vldgroup set to diskgroup will be skipped. diskgroup today includes
disktests, calibration and diskhealth. This is one more way to skip
disktests in addition to the nodisktests option.
Do everything as root user
0. tar -pxvf the ImageMaker.tar file resulting in dl180 or dl360
directory. cd to the directory dl180 or dl360
1. You make PXE build using
./makeImageMedia.sh -pxe [-pxeout &ImageName&]
This will create 3 files in ./PXE directory
kernel - vmlinux-&version&-ImageName-&DL180 or DL360 cell or db respectively&
initrd - initrd-&version&-ImageName-&DL180 or DL360 cell or db respectively&.img
- nfsimg-&version&-ImageName-&DL180 or DL360 cell or db respectively&.tar
The kernel and initrd files are sent to the node being imaged by the PXE
The image tar file should be extracted in the nfs_share directory by root
user as shown in next step.
./makeImageMedia.sh -pxe -pxeout dl180
PXE nfs image: /dani/11132/dl180/./PXE/nfsimg-11.1.3.2.0-dl180-DL180.tar
PXE initrd: /dani/11132/dl180/./PXE/initrd-11.1.3.2.0-dl180-DL180.img
PXE kernel: /dani/11132/dl180/./PXE/vmlinux-11.1.3.2.0-dl180-DL180
2. Prepare nfs share
Copy the nfsimg tar and md5 files to nfs_share directory.
Using nfs_share from the following example, where the nfs server that holds
the image content is 123.45.67.189 and the nfs_share on it is
/vol/exadata/dl180, and assuming the image tar file was in /root.
cp /root/nfsimg-11.1.3.2.0-dl180-DL180.* /vol/exadata/dl180
Releases older than 11.2.1.3.0 should exptract the nfsimg files:
Extract nfsimg-11.1.3.2.0-dl180-DL180.tar to the nfs_share
&tar -x -p -v -C &nfs_share& -f nfsimg-11.1.3.2.0-dl180-DL180.tar&
Using nfs_share from the following example, where the nfs server that holds
the image content is 123.45.67.189 and the nfs_share on it is
/vol/exadata/dl180, and assuming the image tar file was in /root.
&tar -x -p -v -C /vol/exadata/dl180 -f /root/nfsimg-11.1.3.2.0-dl180-DL180.tar&
3. Configure the PXE server
Assume PXE server has both DHCP and TFTP daemons started on it.
Copy initrd and kernel into /tftpboot on the PXE server.
Create DHCP configuration in /tftpboot/pxelinux.cfg/&hexadecimal_ip_address_of_the_imaging_machine&.
You can also use the MAC address for the eth0 NIC for filename instead of
hexadecimal ip address.
For ip address 123.123.123.123 the filename based on ip address will be
If the MAC address is used, and it was 12:34:56:78:90:12, then the file will

Please check your specific PXE server requirements, the above names are what
were used in our testing and your PXE server may need slightly different names
or settings.

Explanation of command line options:
-----------------------------------
- signals this is pxe imaging
mandatory parameter
- print special [FACTORY_...] messages for use by factory.
optional parameter.
- signals to force reimage even if installation exists on the machine
optional parameter
- check hardware and firmware versions. Update firmware where applicable.
optional parameter.
kerver=&kernel_version&
overwrite default kernel. By defaut installing kernel version depends
on hardware type (system product name). List of kernels and hardware
dependencies defined in the &kernel_ver& line at the very top of
makeImageMedia.sh script.
dualboot=&yes|no&
overwtire default dual boot behaviour. It's only applicable for the
db node. By default dual boot feature (installing Linux image and
prereserving space for Solaris) depends on hardware type (system
product name). By default X4170 M2 and X4800 (G5) servers have dual
- dhcp is optional parameter and should NOT be given with eth0 option
If given, dhcp is used to obtain the initial dhcp address instead of
requiring to pass the eth0 information.
ethX=&ip&:&netmask&:&gateway&
- ethX is optional parameter. Do NOT give with dhcp above.
- where X is one of 0,1,2,3 on Sun and 0 on HP machines
If both dchp and ethX are absent imaging will enter
interactive mode and ask for Ethernet ip, netmask and
gateway information
sk=&nfsip&:&nfs_share&
- sk is mandatory parameter for the PXE boot. MUST
use IP address not the hostname for NFS server.
nfs_share is the full path to directory where the 3 files from
PXE directory are available
logpath=[nfsip:]&full path to writeable nfs share&
- logpath is optional parameter
If given it will copy the imaging, zero and first boots logs to the
writable nfs share location in single tar bzip2 file &serial_num&.tbz.
The serial_num is the serial number of the system obtained as
dmidecode -s system-serial-number
-----------------------------------------------
Development ONLY options NOT for use in Factory
-----------------------------------------------
reboot-on-success
- Do not wait for operator to power off machine on successful image, just
reboot. Useful for mass unattended imaging using preconf option.
DO NOT use in factory process.
optional parameter
- Image the node as multi profile enabled
This parameter is optional
NOTE: Do NOT build the images with -multiprof to makeImageMedia.sh
If you do that image can only be used to do multi profile nodes.
nodisktests
- do not run disktests at zero boot. They take 6-14 hours!
This parameter is optional
notests=&group for validations to be skipped, e.g. diskgroup&
- Skips all validations with given vldgroup name. For example, if
diskgroup is given as the group name, then each validation with
vldgroup set to diskgroup will be skipped. diskgroup today includes
disktests, calibration and diskhealth. This is one more way to skip
disktests in addition to the nodisktests option.
This parameter is optional
preconf=[&preconf_nfsip&:]&full path name of preconf_file on nfs server&
- preconf is optional parameter
The nfsip MUST be IP address of the NFS server not its hostname
The preconf_nfsip can be same or different than the nfsip in sk
option, allowing the preloaded configuration file to reside on different
subtree or entirely different nfs server from that of the imaging bits
on the nfsip nfs server.
Installation process
--------------------
Preinstall steps for HP DL180
-----------------------------
Imaging will stop and require you to confirm to continue if:
a) P400 Smart Array disk controller is not in PCIe x8 slot
b) There are additional USB s besides the CELLINSALL USB and the blank
USB for use as CELL boot USB
c) All drives are not identical model and make
On the target machine set up the BIOS boot sequence such that
- Hard disk drives is the first in the boot sequence
- Within the hard disk drives option the USB flash disk(s) are before the P400
disk controller
- Disable removable drives
Use the screen shots in the doc directory as guide.
Preinstall steps for HP DL360
-----------------------------
Imaging will FAIL if following are true:
a) Infiniband card is not in PCIe x8 slot
On the target machine set up the BIOS boot sequence such that
- USB flash is first in the boot sequence
Use the screen shots in the doc directory as guide.
Preinstall steps for SUN X4275
------------------------------
Imaging will stop and require you to confirm to continue if:
a) LSI 9261-8i disk controller is not in PCIe x8 slot
b) There are additional USB s besides the CELLINSALL USB and the blank
USB for use as CELL boot USB
c) All drives are not identical model and make
On the target machine set up the BIOS boot sequence such that
- The CELLINSTALL USB is first in boot order
- The internal CELLBOOT USB (UNIGEN) is the second after the CELLINSTALL
- The LSI disk controller is next
Use the screen shots in the doc directory as guide.
Preinstall steps for SUN X4170
------------------------------
Same as SUN X4275
- Ignore any messages as stated in the Things to ignore section
- If BIOS, Disk controller or disk firmware needs update the imaging
process will update the firmware and try to power cycle the machine
using ipmi.
ALERT: It is possible that the machine may not boot back after such power
cycle due to issues with BIOS boot order being reset or the ipmi
power cycle not properly able to complete. Please manually power
cycle the machine to continue imaging.
- After imaging and automatic creation of the internal CELL boot USB machine
will launch several health checks and long disk tests.
SAS 600GB drive disk tests will take up to 9 hours
SATA 2TB drive disk tests will take up to 14 hours
SAS 450GB drive disk tests will take up to 12 hours
MDL SAS 1TB (SATA 7200RPM 1TB drives) drive disk tests will take up to 48 hours
(A) When Success of validation tests
When all tests pass the machine will indicate the success of installation
on the console and wait for you to power off the machine.
In case of a reimage the machine may come to &localhost login:&
prompt. Login as root/welcome1 and reboot the machine.
(B) When failure of validation tests
When a validation fails the machine will prompt you to choose to rerun
the validations on reboot. You must choose to re-run the tests.
After you finish making the choice the machine will either present
&localhost login:& prompt or exit to a shell. You can logon as root and
password welcome1 if login prompt is presented. Please
1. Examine the log files in /var/log/cellos/validations/
to identify the cause of failure. Correct the problem and
reboot the machine. The machine will rerun the tests unless
you had chosen not to re-run them.
2. If you can not easily identify the cause, please reboot the machine
to see if the checks pass. If you get prompted for hostname and other
configuration information, you should poweroff the machine.
Install steps
-------------
Using CELLINSTALL USB:
----------------------
Insert the CELLINSTALL usb in any USB slot on target machine and boot the machine
- Assuming the machine is bare metal it will automatically boot from the USB and
the imaging process will start automatically
Using ISO:
Boot the system using the ISO and follow prompts. For bare metal imaging
will start automatically
Using ISO+NFS:
-------------
Boot the system with the iso and follow prompts. For bare metal imaging
will start automatically
Using PXE+NFS:
-------------
Boot the system using PXE by pressing F12 after during BIOS
initialization splash screens. For bare metal imaging
will start automatically.
You can also use &ipmitool chassis bootdev pxe& from already imaged
system, to force the system to boot one time on next reboot.
This is useful for mass re-imaging of systems.
Unattended first boot configuration:
-----------------------------------
There is now support for unattended first boot configuration as
long as you build it in the image.
The steps to use unattended first boot configuration need you
to build the image media with new option to makeImageMedia.sh
See the sample_preconf.csv file for example preconfiguration file.
This file can be
(A) passed to the makeImageMedia.sh, and/or
(B) it can be copied to the nfs_share location when using PXE and/or
(C) it can be copied to the nfs_share/nfs_dir location if using nfs iso.
(D) it can be copied to the / directory of the install USB
If the file is inserted in the install media using (A), and if it
is also passed with methods (B) to (D), then the file from (B) to
(D) takes precedence over the file passed using (A).
This allows you to update the file after creating the installer media
- USB or the iso+nfs or the pxe+nfs, so that you can image more
machines using the same media.
Preparing the preconf.csv file:
-------------------------------
1. First line with &Cell Preconfig version& is mandatory
2. Title line starting with &Hostname, Domain, ....& is mandatory
and format is fixed
3. You MUST NOT change these two lines.
4. The line started with &common& keyword in Hostname column is
optional, and provides a way of supplying common values.
4.1. The &common& line MUST not contain these
a. &eth0 mac address&
b. &eth0 ip&
c. &bond0 ip&
d. &hostname&
4.2. Multiple &common& lines are allowed. Each next common
line overwrites all previous common settings.
5. Any individual line for the host MUST have unique hostname, eth0
mac address, eth0 ip and bond0 ip values.
5.1. If individual column is empty the value from the common
column is used
5.2. All values are mandatory except nameservers and NTP servers
5.3. The full hostname is result of &$HOSTNAME.$DOMAIN&
5.4. Nameservers and NTP servers have to be separated by space.
6. Any line starting with # is treated as comment line.
NOTE: It's a good practice to validate syntax of .csv file. You can do it using
&dl180 or dl360&/initrd/opt/oracle.cellos/ipconf -verify -preconf &path_to_csv_file&
dl180 or dl360 are top level directories when you extract the ImageMaker
tar.zip files.
--------------------------------------------------------------------------------
SAMPLE of preconf.csv file - See csv files in /opt/oracle.SupportTools/firstconf
--------------------------------------------------------------------------------
Things to ignore safely during install:
--------------------------------------
1) &cciss/cXdYpZ Invalid partition table&
The above message will repeat several times with X,Y, and Z are some integers
- X is the P400 smart array disk controller slot number
- Y is the disk number starting with 0 for the slot
- Z is the partition number on the disk
Reason for this is unknown and the message is harmless
1) &RAID1 conf printout:...&
This is the software RAID printout we are not yet able to find a way to suppress
2) tar: &file&: &date stamp& is X s in future
Known Issues and work around:
-----------------------------
1) ONLY on HP DL180: With the install USB and a blank USB in the machine, you may get &Disk
error. Invalid disk press any key to continue...&
Please fix the BIOS boot sequence as indicated in various screen shots
(.gif files in ScreenShots directory)
2) Installer USB does not work from some USB slots:
Solution: Try different slots - if all else fails create fresh usb and try if that also
fails get a new machine.
Miscellaneous tips:
-------------------
NOTE: 1) The disk controller on the Exadata cell nodes
must be in PCIe x8 slot for optimal
performance (performance can degrade 50% if this is not the case).
2) The Infiniband card must be in PCIe x8 slot on compute aka database nodes
You can confirm the speed of the slot as follows:
as root run command lspci -vvv on freshly imaged box and check for the Link speed for disk
controller, the Infiniband cards.
Look at line marked ===& in the sample outputs of the lspci -vvv command below.
You should have matching lines for the disk controller and Infiniband
cards on your machines - If NOT then you will need to open the machine
and relocate the corresponding cards to correct slots

###########################
SUN FACTORY OVERALL PROCESS #################################################
As of Sep 27, 2009:
NOTE: ----------------------------
ALL steps below assume at most single DBM i.e. one full rack.
If more than one DBM are to be interconnected, then the below scheme needs
to be modified accordingly to avoid ip address conflicts.
NOTE: ----------------------------
The factory process at SUN will make 2 imaging passes using PXE+NFS.
The first successful imaging pass will leave the systems (X4170 and X4275)
configured with all the basic network information such as the hostname, ip
address, etc. Factory will do this using the preconf option to imaging to
feed the configuration information. The exact mandatory PXE options are
listed below. Once the nodes are fully up, factory can run various tests
on them. The mandatory tests are listed below.
Assuming all tests pass in the first round, the second round of imaging
will wipe out the first image and re-image the nodes. This round will use
different options to PXE. The list of options to use is listed below.
This second round will leave the systems configured with fixed private
hostnames, ip addresses as oulined in following sections.
To do this Factory will need to ensure that the MAC addresses for eth0
interfaces used in the first round are plugged in to the template preconf
file for second round in exact order as documented in the template file.
Factory will need to confirm at end of round 2 that the systems can come up
and carry the private ip addresses and hostnames.
Note that &pxe& and &sk& options are mandatory for PXE.
Out of optional parameters:
Round 1 image PXE options:
--------------------------
3. factory
4. reboot-on-success
5. preconf
Must NOT use:
1. notests=diskgroup
2. multiprof
Round 2 image PXE options:
--------------------------
3. factory
4. notests=diskgroup
5. preconf - based on second round template
6. reboot-on-success
Must NOT use:
1. multiprof
Distributed/Rack-wide tests to be run after successful image at Round 1:
-----------------------------------------------------------------------
Login to any one node as root/welcome1. Let us call this the master
test node (MTN).
0. Examine the validations success
a. cd /var/log/cellos
b. Examine the file vldrun.xx.log for any failures. If there are
failures, then examine for each failed validation the, suggested
remedy file &&validation name&.SuggestedRemedy& in the validations
subdirectory.
If no remedy file exists look for the corresponding log files to
track down the failure cause and correct it.
1. Check Infiniband Switch software and firmware versions
a. cd /opt/oracle.SupportTools
b. ./CheckSWProfile.sh -I &comma separated list of switch ips no spaces&
Follow prompts
2. Establish root user ssh equivalence between MTN and any other node:
a. ssh-keygen -t dsa
b. ssh-keygen -t rsa
Accept defaults so the ssh keys are created for root user
c. create a file called &nodes& listing one hostname (short hostname -
i.e. hostname -s output) per line for all nodes in the rack.
d. cd /opt/oracle.SupportTools
e. ./setup_ssh_eq.sh &full pathname to the nodes file& root welcome1
This pushes the ssh keys to all nodes establishing the ssh trust for root
user to all nodes from MTN.
3. Verify the Infiniband connectivity and topology:
a. cd /opt/oracle.SupportTools/ibdiagtools
b. ./verify-topology -factory [-t quarterrack]
Sample output of this for successful runs is in SampleOutputs.txt file in
same directory for a full rack.
4. Check that the Infiniband performance is acceptable. Failures indicate
problems with links, badly seated HCA s, wrong configuration on switch,
a. cd /opt/oracle.SupportTools/ibdiagtools
b. Create a file of DB nodes (Sun X4170 or HP DL360) one Infiniband IP
address per line. If there are less than 8 nodes in full DBM and less
than 4 in half DBM there is some problem in IB connectivity
ibhosts | awk '/S [0-9.]* / {print $8}' | tee dbips.ora
c. Create a file of Cell nodes (Sun X4275 or HP DL180) one Infiniband IP
address per line. If there are less than 8 nodes in full DBM and less
than 4 in half DBM there is some problem in IB connectivity
ibhosts | awk '/C [0-9.]* / {print $8}' | tee cellip.ora
d. Setup all to all root user ssh equivalence
d.1. Create a file allip.ora with one ip address per node
ibhosts | awk '/[SC] [0-9.]* HCA\-1/ {print $8}' | tee allip.ora
Now use the setup_ssh_eq.sh script to setup user equivalence from
current node to all other nodes without a password
../setup_ssh_eq.sh allip.ora root &root_password&
d.2 Now to setup user equivalence between all other nodes in the rack..
./infinicheck -b -g dbips.ora -c cellip.ora -u root -s
Respond to prompts or you can expect script this part and automate
e. Create a smaller file dbip.ora out of dbips.ora with just one ip per
compute node. So if there are 2 compute nodes with 4 HCAs,
then dbip.ora should just have 2 ip address from each node.
ibhosts | awk '/S [0-9.]* HCA\-1/ {print $8}' | tee dbip.ora
f. Run the check. Option -b for bare metal will suppress the warnings
about cellinit.ora and cellip.ora files not found.
./infinicheck -b -g dbip.ora -c cellip.ora
g. To view only performance run results
./infinicheck -d -p
h. To clean up after a run
./infinicheck -z
Details for Round 2:
-----------------------------------------------------------------------
1. Before starting reimage for round 2, copy the file somewhere
/opt/oracle.SupportTools/firstconf/factory_use_only.csv
2. Edit the copied file to add the MAC addresses for nodes. Pay
close attention to the order in which addresses are entered.
The nodes are organized in top to bottom ordering in the rack.
The existing MAC addresses are sample only and should be written
over with real MAC addresses.
Populate these only for the type of Database Machine (DBM) in
build. For example only fill up the half rack section for half
rack. Leave the rest alone.
Verify basic form and content of the file by
/opt/oracle.cellos/ipconf -preconf &the csv file& -verify
3. The above edited file should be used as the preconf.csv file
to reimage the nodes for Round 2.
4. Once the nodes are up, login to the console (root/welcome1) of
the bottommost DB node (X4170) in the rack. This should have
come up with hostname fdata01 or hdata01 or qdata01 or bdata01
corresponding to full, half or quarter DBM.
5. cd /opt/oracle.SupportTools
6. ./setup_ssh_eq.sh \
/opt/oracle.SupportTools/firstconf/&full | half | quarter& \
7. Check that root ssh equivalence was set up correctly in above step
by simply executing some simple ssh command:
/usr/local/bin/dcli \
-g /opt/oracle.SupportTools/firstconf/&full | half | quarter& \
&hostname -i&
8. Set the ILOM ip addresses as specified in
/opt/oracle.SupportTools/firstconf/factory_use_only.csv
9. Set the NM2 InfiniBand switch ip addresses as specified in
/opt/oracle.SupportTools/firstconf/factory_use_only.csv
10. Set the CISCO Ethernet switch ip addresses as specified in
/opt/oracle.SupportTools/firstconf/factory_use_only.csv
11. When the above step passed, power off the nodes. They are ready to ship.
Round 2 variation if Round 2 above does not work and there is time
----------------------------------------------------------------------------
This is the case where you ship the rack without setting up private IP
addresses.
Simply reimage the rack but this time use the options:
3. factory
4. notests=diskgroup
Must NOT use:
1. preconf - based on second round template
2. multiprof
3. reboot-on-success
What happens at customer site when machine ships with private ips
-----------------------------------------------------------------
At customer site, to apply real configuration the customer prepares the
preconf.csv file that has all the correct content.
0. Log in to the bottommost DB node as root/welcome1
1. cd /opt/oracle.SupportTools/firstconf
2. copy the customer preconf
3. ./applyconfig.sh \
&full | half | quarter& \
&full path to preconf.csv file e.g. /root/preconf.csv&
4. This will push the configuration to all nodes and reboot them.
Solaris installation
--------------------------------------------------------------------------
To install Solaris you have to install or reinstall Linux with dualboot option
first and make sure that the Linux installation succeed. You should use
ForFactorySolaris zip file to deploy PXE server. The README file in the factory
zip explains the details.
You also have the option to use the iso for Solaris installtion. ISO based
installation is completely unattended, thus you need only boot from the disk
and wait till the machine reboots after the sucessful installation. It may take
up to several hours. You can check status of the process:
0. Log in to the DB node as root/welcome
1. tail -f /tmp/install_log
