    The disk is from SAN. I can clear remove the disk using rmdev.But if i run cfgmgr , this disk apperas with PVID. Please suggets how to clear PVID.

    Try to rmdev -dl hdiskN, un-map it on your storage box, map it back, run the cfgmgr and try again.

    Ensure this disk is not part of any other servers like shared disk.

    chdev -l <hdisk#> -a pv=clear is right and enough command to clear the PV.

    If the PVID is setting back, then something is abnormal here.

    You can also check with the SAN team to verify this disk is mapped to any other servers / wwpns by providing the LUN ID.

    Even after verify the above steps, if still the disk is shows the PVID, then you clean the disk.

    dd if=/dev/zero of=/dev/rhdisk# bs=64k count=100
    rmdev -dl hdisk#
    cfgmgr -v
