  1. how to check status of mirror handled by BIOS?


    i have a dell 2950. the system disks are mirrored in hardware
    at the BIOS level. the OS thus only sees one disk.

    can i check the status of the mirror without rebooting?
    the lights are blue, not orange, but i'd like a way to
    confirm that the mirror is up and synced. the disk
    activity lights flash like they should, but.... i'd
    like a warm fuzzy.

    any way? thx in advance.

    Do you have a true hardware RAID controller, or are you using what's called
    BIOS RAID (aka ATARAID, fakeraid)? This is not true hardware RAID.

    What lights? Where are they? What are they connected to?

    AFAIK most hardware RAID controllers *do* have a way of letting you monitor
    the status of the mirror without rebooting. You will need to look up the
    exact model of your controller, but it should be possible.

    AFAIK most fakeraid controllers do not have such a facility. I could be
    wrong, but mine certainly needs a reboot in the BIOS to do any management or
    monitoring of the arrays (it's a Silicon Image SiI3112A).

    If you don't know which you have, capture the output of lspci and post it
    here.

    Iirc "dell 2950" sounds like a 19" rack server, so I guess it is
    a real hw raid controller. 'lspci' should tell more, usually Dell
    provides software for online checking. Some driver in addition
    log faults to the kernel, though not all.

    Checking which controller/driver is used and trying to find the
    app to check/configure it sounds like the best idea.
