    Steve -
     
    Interesting .. have only seen this on rare occasions.....
     
    Run the following command to see what the disk actually knows about the
    volume group:
     
    #>lqueryvg -Atvp hdisk0
     
    This will read the vgda on the disk .. look at the items under Physical
    .. this will tell you what PVIDs are in
    rootvg as seen by the disk... see if 00c0b84e228a7fcd is in the list...
     
    Run the next command to see if if ODM agrees with what you see on the
    disk.
     
    #>odmget -q "name=rootvg and attribute=pv" CuAt
     
    See if 00c0b84e228a7fcd is again on the list...
     
    1) if both agree... reducevg didn't work ..
     
       execute the reducevg command again and re-run both of the previous
    commands to see if they agree now
     
     
    2) Disk VGDA says hdisk1 is IN the volume group and ODM says the disk is
    NOT in the volume group..
     
         ODM is correct in your situation but the disk did not get updated
    correctly ...
     
         #resync the VGDA with the ODM information
         #>synclvodm -v rootvg
     
             Re-run the the two commands and see if everyone agrees
     
     
    3) Disk VGDA says hdisk1 is OUT of the volume group and ODM says is in
    the volume group..
     
          Highly unlikely....
     
          Match a odmdelete to remove the entry....
     
     
    Good hunting ..

    Subject: Can't remove hdisk from rootvg

    My new P5 550 came with AIX 5.3 preloaded onto hdisk1. I wanted to move
    everything onto hdisk0. I followed the following steps:

    migratepv -l hd5 hdisk1 hdisk0

    bosboot -a -d /dev/hdisk0

    bootlist -m normal hdisk0

    mkboot -c -d /dev/hdisk1

    smit migratepv

    reducevg rootvg hdisk1

    rmdev -l hdisk1 -d

     

    Everything worked great. The problem that I am having is when I run
    cfgmgr, hdisk1 gets added to rootvg. Although rootvg knows nothing
    about it.

    Any ideas?

     

    Thanks.
