    Hi All,

    Is there any steps to recover the VGDA? am getting "Unable to read the specified physical volume descriptor area" while performing triggering the AIX commands.

    1. lsvg -p rootvg
    0516-040 : Unable to read the specified physical volume
    descriptor area.
    Thanks,
    Karthik

    Take a look at errorlog first using the errpt command. Probably your rootvg disk has a problem.

    What kind of memory error ? I had a situation with an LPAR where several commands were failing. All I had to do was to increase the memory via DLPAR. Could that be your situation too ?

    If it because of Memory issue ,then none of the command will execute, while executing commands will encounter "fork error" right , but here we are getting error only when the commands read the data (VGDA) from Physical volume.

    In the issue I had, new processes were being forked successfully and I was able to run most AIX command normally.

    It were the LVM commands against rootvg that would fail : lsvg, lqueryvg,lquerypv, readvgda, etc ... were all reporting errors similar to yours. Your case could be different.

    Thanks for the Information provided, i thought VGDA might got corrupted, but when i read the VGDA information from PV , am able to do so there is no issue in VGDA as well as PV

    will increase the Memory for that LPAR & update the forum.

    Thanks,
