一.磁盘克隆安装操作系统。
1.操作系统环境。# oslevel -s
6100-04-10-1119
# bootlist -m normal -ocd0
hdisk0 pathid=0
ent0 speed=auto duplex=auto bserver=000.000.000.000 client=000.000.000.000 gateway=000.000.000.000
# lspv
hdisk0 00cc1ad4ef095bf0 rootvg active
hdisk1 00cc1ad46aff307f None
2.使用alt_disk_install工具克隆磁盘。
# alt_disk_install -OCB hdisk1
+-----------------------------------------------------------------------------+
ATTENTION: calling new module /usr/sbin/alt_disk_copy. Please see the alt_disk_copy man pageand documentation for more details.

执行这个命令需要bos.alt_disk_install.rte软件包。alt_disk_install -OCB hdisk1
这个命令克隆的盘，可以拿到不同硬件配置的服务器上使用，使用它进行引导时，会删除ODM库里的所有信息，根据硬件重新配置所有设备信息，相当于使用克隆盘重新安装新的系统。
alt_disk_install -CB hdisk1
如果是相同硬件配置的机器，则可以运行这个命令克隆磁盘，保持所有设备信息。
3.查看克隆情况。# lspv
hdisk0 00cc1ad4ef095bf0 rootvg active hdisk1 00cc1ad46aff307f altinst_rootvg #alt_disk_install -X #rmdev -dl hdisk1
hdisk1对应的卷组名为altinst_rootvg。
# bootlist -o -m normalcd0
hdisk0 pathid=0
ent0 speed=auto duplex=auto bserver=000.000.000.000 client=000.000.000.000 gateway=000.000.000.000
查看引导列表，未发生变化。
4.重启操作系统。# lspv
hdisk0 00cc1ad4ef095bf0 rootvg active hdisk1 00cc1ad46aff307f altinst_rootvg # bootlist -o -m normalcd0
hdisk0 pathid=0
ent0 speed=auto duplex=auto bserver=000.000.000.000 client=000.000.000.000 gateway=000.000.000.000卷组名和引导顺序未发生变化。
5.拔掉克隆磁盘。
关闭操作系统，拔掉hdisk1，重启源服务器，查看服务器情况：# lspv
hdisk0 00cc1ad4ef095bf0 rootvg active # lsdev -Cc disk
hdisk1 Defined 01-08-00 SAS Disk Drive
删除被拔掉的磁盘： # rmdev -dl hdisk1 hdisk1 deleted # lsdev -Cc disk
hdisk0 Available 01-08-00 SAS Disk Drive
6.将克隆磁盘移植到新服务器。
hdisk0 Available 01-08-00 SAS Disk Drive
将hdisk1插入新服务器，新插入的盘不会自动引导系统的启动，需要在分区启动时进入SMS菜单，手动指定磁盘启动。
1).进入SMS菜单，选择5：
2).选择1：
3).选择7：
4).选择3引导系统：
5).选择2：
6).选择1：
7).选择2：
7.检查系统：# lspv
hdisk0 00cc1ad46aff307f rootvg active # lsdev -Cc disk
hdisk0 Available 00-08-00 SAS Disk Drive# bootlist -o -m normalcd0-
ent0 speed=auto duplex=auto bserver=000.000.000.000 client=000.000.000.000 gateway=000.000.000.000
修改引导顺序：
# bosboot -a -d /dev/hdisk0
bosboot: Boot image is 53276 512 byte blocks.# bootlist -o -m normal hdisk0
# bootlist -o -m normal hdisk0 blv=hd5 pathid=0
hdisk0 blv=hd5 pathid=0自此，分区重启即可自动启动。
