Thread: pSeries with generic or xSeries HDDs

  1. pSeries with generic or xSeries HDDs

    Hi ppl.

    We have an old p660 (7026-6H) machine, which cointains four dead 73Gb/
    10k U320 disks (07K9429). Disks installed in EXP710, and EXP710
    connected to server via SCSI cable. My local IBM dealer said - 07K9429
    are windtrawn product and out of ordering. Can I use any other
    TotalStorage or xSeries disks with same interface (u320/80 pin, e.g.
    40K1027) ?

    Thanks in advance!

    If you search most on-line vendors for either seagate or hitachi SCSI HDD's
    with the same 80 pin connector they should work just fine. lsdev -C will
    show them as "other disk device" but they will function and perform just
    perfectly and they will cost much, much, much less.

    Good luck.

    I have experience that Compaq's disk successfully replaced disk in
    pSeries 610. Just had to put it in pSeries' disk sled.

    Actually, they'll perform good if you enable tagged command queueing. On
    drives with non-RS6k firmware TCQ is disabled by default, mostly for
    historical reasons nowadays since SCSI drives has reliably supported TCQ
    for quite some time now.

    To enable TCQ, do something like:
    chdev -a queue_depth=8 -a q_type=simple -l hdiskX

    For more information, read the relevant IBM manual.
