rootvg引导列表的pathid问题咨询

建议你还是不要搞了，你搞这些有啥意思不？只要系统能正常使用就行了收起

怎么改，还是没搞定啊收起

    想把hdisk0和hdisk1都改成pathid=0怎么改收起

   想改成hdisk0和hdisk1的pathid都是0，改不了啊
# bootlist -m normal -o
hdisk0 blv=hd5 pathid=1
hdisk1 blv=hd5 pathid=0

# bootlist -m normal hdisk0 blv=hd5 pathid=0
0514-232 bootlist: The device does not contain one or more of the paths provided
# lspath
Enabled hdisk0 sas2
Enabled hdisk1 sas2收起

对于rootvg的磁盘出现pathid，通常都是san boot方式，才会有这种情况！收起

专家正解:lol收起

lspath  -t hdisk0
lspath -t hdisk1
命令敲完，可以看到pathid了
至于pathid有啥意义呢
In AIX 6.1 TL 6 (6100-06-00) a new feature was added to allow a system administrator to specify which paths would be used to boot from in a multipath environment. This was added by APAR IZ72620 (PTF U838753). The feature was also added to AIX 7.
BOOTLIST OUTPUT
The bootlist will now print the path ID of each path on output:

      # bootlist -om normal
      hdisk0 blv=hd5 pathid=0
      hdisk0 blv=hd5 pathid=1

In this example there are two paths to the boot disk.


SETTING THE BOOTLIST
To set the bootlist to specific paths, list each path on the command line:

      # bootlist -m normal hdisk0 blv=hd5 pathid=0 pathid=1
or
      # bootlist -m normal hdisk0 blv=hd5 pathid=0,1

Using this method paths can be ignored or deleted from the boot list. This may be necessary if there are more than 5 paths to a boot device, as the Open Firmware for pSeries systems only allows 5 devices (or paths) maximum in the boot list.

Path ordering is also maintained in the bootlist. If a user wishes to have paths 2, then 1, then 0 searched or booted from, using "pathid=2,1,0" will follow this ordering during the boot
