详解使用磁盘克隆和U盘安装IBM AIX操作系统
通常我们都是通过CDROM的方式来安装IBM AIX操作系统，但如果服务器没有光驱，或者需要安装多台服务器的时候为了提高工作效率，可以考虑使用这里的方法。这篇文章将详细讨论使用磁盘克隆和U盘安装的方式安装AIX操作系统，这两种方法都需要有已经成功安装的AIX操作系统的支持。
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 -o
cd0
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 page
and documentation for more details.
Executing command: {/usr/sbin/alt_disk_copy -O -B -d "hdisk1"}
+-----------------------------------------------------------------------------+
Calling mkszfile to create new /image.data file.

Fixing file system superblocks...
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。
hdisk0 00cc1ad4ef095bf0 rootvg active
hdisk1 00cc1ad46aff307f altinst_rootvg
hdisk1对应的卷组名为altinst_rootvg。
# bootlist -o -m normal
cd0
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 normal
cd0
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
hdisk0 Available 01-08-00 SAS Disk Drive
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。
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 normal
cd0
-
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
hdisk0 blv=hd5 pathid=0
# bootlist -o -m normal
hdisk0 blv=hd5 pathid=0
自此，分区重启即可自动启动。
二.使用U盘安装操作系统。
使用U盘安装AIX的方法描述：
USB flash disk(U-disk)
IZ15299 6100-02
IZ20527 5300-09
add boot support for USB flash memory device.
These APAR announced Nov 2008,3 years ago.
3 type of U-disk are formally supported:
-Lenovo USB2.0 Essential Memory Key, part number 41U4944
-Kingston 4GB DataTraveler, USB2.0
-SanDisk 4GB Cruzer Micro Flash Drive, USB2.0
Procedure to create bootable U-Disk
1)plug U-disk in USB port
2)make sure below filesets installed.
devices.common.IBM.usb.rte
devices.usbif.08025002.rte
3)Configure U-disk
#cfgmgr -vl usb0
usbms0 Available 2.3 USB Mass Storage
#lscfg -vl usbms0
usbms0 U78C0.001.DBJA161-D1-T1-L1 USB Mass Storage
Manufacturer................San
Machine Type and Model......Cru
ROM Level.(alterable).......8.01
4)Copy ISO from DVD
#dd if=/dev/cd0 of=/images/AIX61.iso bs=4096k
make sure iso file is in a large file capable file system and has enough space
#dd if=/images/AIX61.iso of=/dev/usbms0 bs=4096k
Do not use U-disk with write protection switch.AIX will complain the U-disk
is write protected no matter it is write protected or not.(Bug)
Procedure to install from U-disk
1)insert U-disk created in Power computer node USB port
2)activate LPAR to SMS
3)Multiboot -> Select Install/Boot Device -> Select harddisk/USB

946+1 records out.
# dd if=/opt/AIX61.iso of=/dev/usbms0 bs=4096k
946+1 records in.
946+1 records out.
在现有AIX操作系统上完成以上步骤之后，将USB盘插入到新服务器或分区，启动分区或服务器，进入SMS菜单：
参考上面的内容选择USB引导启动，选择5：
成功通过USB引导：
之后的步骤跟CDROM安装是相同的。
