如何更改hdisk的号码

怎么将pdisk加到指定的hdisk？

两边都删除，重新自动认，终于一致了

再教你一个办法：

有的时候由于个种原因导致rootvg安装在了hdisk2上，往往会引起操作时的混淆。以前以为rootvg就没法改回来了，以前只能加块盘，mirror之后，使剩下hdisk0，系统导过去。现在可以用这个试下，IBM上看到的，注意先备份系统，以防万一。


重启系统后硬盘的名字顺序会根据设备配置过程中的顺序来决定，例如，在地址00-00-0S-00的硬盘编号将会在地址是00-00-0S-20 和 00-05-00-00的硬盘
之后。

lsdev -Cc disk | awk '{ print $1 }' | while read HDname; do
odmdelete -q "name = $HDname" -o CuAt
odmdelete -q "value = $HDname" -o CuAt
odmdelete -q "name = $HDname" -o CuDv
odmdelete -q "value3 = $HDname" -o CuDvDr
odmdelete -q "name = $HDname" -o CuVPD
done
rm -f /dev/hdisk*
rm -f /dev/rhdisk*
savebase

执行完后，用以下命令重启机器，之后硬盘顺序将变为有序状态：

貌似与楼主需求不符～

呵呵，参考下思路即可。

7133 service guide上写的很清楚啊。

1. Find the pdisk or hdisk number that you want to change, and select a new (unused)
name.
2. Give the command:
lsdev -Cl [disknumber] -Fconnwhere
where [disknumber] is the pdisk or hdisk number (for example, pdisk0) that you
want to change.
The command returns a ConnectionLocation number (for example,
004AC5119E000D).
3. Make a note of this number; you will need it later in this procedure.
4. Give the command:
lsdev -Cl [disknumber] -Ftype
where [disknumber] is the pdisk or hdisk number (for example, pdisk0) that you
want to change.
The command returns the device Type for the disk.
5. Make a note of this device type; you will need it later in this procedure.
6. Remove the existing pdisk or hdisk number from the configuration. Give the
command:
rmdev -l [disknumber] -d
where [disknumber] is the pdisk or hdisk number (for example, pdisk0) that you
want to remove.
7. Give the command:
mkdev -pssar -t [Type] -c [Class] -s ssar -w [ConnectionLocation] -l [NewDiskName]
where:
[Type] is the disk type that you noted in step 5.
[Class] is pdisk for a pdisk, or disk for an hdisk.
[ConnectionLocation] is the number that you noted in step 3.
[NewDiskName] is the pdisk or hdisk number (for example, pdisk0) that you want
for the disk.
For example:
mkdev -p ssar -t scsd -c pdisk -s ssar -w 004AC5119E000D -l pdisk50
