Thread: Enterprise Storage Array/HSZ70 controller questions

  1. Enterprise Storage Array/HSZ70 controller questions

    Hi, we've still got an Enterprise Storage Array with HSZ70 controllers
    in use (not in production, thankfully), connected to an Alphaserver
    4100 running VMS.

    One of the drives in the array seems to have failed (the orange light
    started blinking). Reseating it resulted in no change. We were able
    to get our hands on "new old stock" of the same drive (I took the hot-
    plug container apart), and now when I plug it in with the new drive
    the green light along with the orange light come on for about 5-10
    seconds, then they both go out, then the orange light starts flashing
    again.

    As we don't have any manuals for the thing anymore and I can't find
    anything really helpful on HP's site, I'm just wondering if I'm doing
    everything correctly - eg, I'm assuming the array works like a modern
    array - if a drive fails, plug in a replacement of the same specs and
    it should rebuild that drive automatically.

    Otherwise, I guess I'm going to have to assume that particular slot on
    the array has gone bad..

    Thanks for all suggestions.

    You may have to delete the container(s) (unit, mirror/RAID/stripe-set) that
    drive was a member of, depending, then delete the device and add it back (RUN
    CONFIG), then add the container(s) back. See the HSZ CLI reference manual, if
    you have it.

    It's possible the HSZs won't realize the device was replaced until you do that.

    I don't know but I assume: that the HSZ set the drive at that position
    to be 'failed' means as a member of the FAILEDSET. You know, you have
    RAIDSETs or MIRRORSETs and (hopefully) one or more drive in the SPARESET.

    When the HSx detects a drive becoming bad, it moves it to the FAILEDSET
    and move a drive from the SPARESET to the MIRRORSET/RAIDSET with now
    a disk less and starts to rebuild this MIRRORSET/RAIDSET automatically.
    You can influence HOW the recovery happens (faster or not to influence
    the host).

    A manuals is not always up to date. Use HELP in the software.
    At least it corresponds to the sw version you run...

    Yes it does. As long as you did/do your job to help it.

    >Otherwise, I guess I'm going to have to assume that particular slot on

    No. The drive in the slot is still marked as failed. You need to tell
    that you replaced the drive. Means you need to remove the slot out of
    the FAILEDSET (and into the SPARESET again).

    Good luck
