    0516-792 extendvg: Unable to extend volume group.

    root@dmap1:/>oslevel -r
    5300-01

    And we are getting the 4 different disks with same  PVID.

    hdisk8          00c77e3b9b5d4ed6                    None
    hdisk9          00c77e3b9b5d4ed6                    None
    hdisk10         00c77e3b9b5d4ed6                    None

    Hi,

    Can you please send the all the error messages when you are running the extendvg** command? Please also refer to the below knowledge base article.

    Unable to add a new disk to a Volume Group due to mismatch in disk block size.

    Hi,

    your oslevel is a little bit old :-)

    I think what you see are the pathes of the disk. Make „rmdev -dl hdiskX (for each disk)", install the req. ODM fileset of Storage Vendor and run „cfgmgr". After that you should see only one Disk with 4 Pathes.

    Best regards
    Manfred
