  • 1.  V7000 - ghost drive removal

    Posted 05/11/23 04:22 AM

    Hi,
    I have, by mistake, swapped a V5000 drive into a V7000, after this replaced the V5000 drive with the correct V7000 drive.  Now I am stuck with a ghost drive which I cannot figure out to remove.

    Drive information:
    >lsdrive |grep -v online
    id  status  error_sequence_number use    tech_type     capacity mdisk_id mdisk_name member_id enclosure_id slot_id node_id node_name auto_manage drive_class_id
    178 offline                       failed unsupported   7.3TB                                                                         inactive

    Normal I remove these using chdrive, but that does not work here:
    >chdrive -use unused 178
    CMMVC6595E The command cannot be initiated because a drive that you have specified has a technology type that is not supported for the command.

    I have tried to reboot the active node to get rid of it, but it still hangs on.

    Any clues to how this can be removed?

    /John

    Hi John,

    what code level is the V7000 running at the moment?

    In fact there is an issue with unsupported "ghost drive" back at certain code levels.
    We can provide an ifix to remedy this.
    If need be, you might need to raise a support ticket to get hold of that ifix.

    Best regards, 
    Christian Schroeder

    Hi Christian,

    The system is a 2076-524 running code level 8.4.0.6, as the system is old it is no longer in IBM service, in this case is it still possible to raise a support ticket?

    I am afraid it is not possible to supply the ifix then.
    As I have learned in that context though, it's rather a cosmetical issue which can be safely ignored.
    Sorry for not being able to be more helpful on this.

    Hi Christian,
    I suspected so, yes I know it is cosmetic, however it is annoying (to me at least :-)), what I was looking for was some command that could fix it for me (a variation on chdrive for instance). :-)

    I do 100% believe this being an annoyance!
    Using chdrive command under normal circumstances is the way to go. 
    The misbehaviour of the sticky ghost drive only occurs with drives bearing a vendor_id which is not supported for this particular system. That's why a fix had to be created to resolve this.

    If it is a real problem, I am told by the team that a lot of fixes associated with this behaviour were delivered into 8.4.0.10 (where 8.4.0.11 is the latest).  Worth reaching out to see if you can negotiate getting the later levels of software supported on your hardware depending on support contract stuff.
