IBM AIX alt_disk_install快速复制系统介绍

alt_disk_install 是aix中一个非常好用的工具，其中一个最经常用到的功能就是复制系统。尤其在多台服务器/分区环境要求一致，但是需要快速部署的情况下。

下面的例子就是把已经在服务器上在hdisk0部署好的系统复制到hdisk2上，具体过程如下，所用命令用加重字体显示：

# lspv

hdisk0 0001d2613c5c29e9 rootvg active

hdisk2 0001f0755343a7f3 None

hdisk3 0001fe75533b6410 None

# alt_disk_install -C -O hdisk2

Calling mkszfile to create new /image.data file.

Checking disk sizes.

Creating cloned rootvg volume group and associated logical volumes.

Creating logical volume alt_hd5

Creating logical volume alt_hd6

Creating logical volume alt_hd8

Creating logical volume alt_hd4

Creating logical volume alt_hd2

Creating logical volume alt_hd9var

Creating logical volume alt_hd3

Creating logical volume alt_hd1

Creating logical volume alt_hd10opt

Creating logical volume alt_fwdump

Creating /alt_inst/ file system.

Creating /alt_inst/home file system.

Creating /alt_inst/opt file system.

Creating /alt_inst/tmp file system.

Creating /alt_inst/usr file system.

Creating /alt_inst/var file system.

Creating /alt_inst/var/adm/ras/platform file system.

Generating a list of files

for backup and restore into the alternate file system...

Backing-up the rootvg files and restoring them to the

alternate file system...

Modifying ODM on cloned disk.

Building boot image on cloned disk.

Resetting all device attributes.

NOTE: The first boot from altinst_rootvg will prompt to define the new system

console.

forced unmount of /alt_inst/var/adm/ras/platform

forced unmount of /alt_inst/var

forced unmount of /alt_inst/usr

forced unmount of /alt_inst/tmp

forced unmount of /alt_inst/opt

forced unmount of /alt_inst/home

forced unmount of /alt_inst

Changing logical volume names in volume group descriptor area.

Fixing LV control blocks...

Fixing file system superblocks...

Bootlist is set to the boot disk: hdisk2

hdisk2 0001f0755343a7f3 altinst_rootvg

# alt_disk_install -X

Bootlist is set to the boot disk: hdisk0

# rmdev -dl hdisk2

hdisk2 deleted

把hdisk2拔下来，放到新的机器/分区中，启动就可以了，这样一台变两台，两台变四台，很快

1，第一台服务器的操作系统要安装完整，补丁打好，需要集群的机器可以把oracle等软件装好，补丁也打好（这个是NIM做不到的，当然，前提是把这些东西放到rootvg当中），一定要确定好整体环境，不然以后一台一台补装软件可不好玩，这个是NIM的强项，呵呵。

2，拔下硬盘或者用分区把硬盘装到别的服务器/分区的后，第一次启动的时候，可能提示找不到可供启动的硬盘，这时候可以进入sms设定一下启动顺序，设定启动顺序的时候sms可以扫描硬盘，发现上面的操作系统。(darkbug)
