    Hi all,
    I need some sage advice.

    I have a Sunfire system running Solaris 8 and a A1000 attached for storage

    I got some error messages from the Raid Manager as follows yesterday

    Jul 28 01:49:24 egsorc002 raid: [ID 702911 user.error] AEN event
    Host=egsorc002 Ctrl=1T030153

    00000000000

    And one of the drives now has a 'yellow' indicator instead of green
    I assume that means it is a problem?

    When I do a drivutil on the array I get this though

    # /usr/lib/osa/bin/drivutil -l LH_UltraII_001
     Logical Unit Information for LH_UltraII_001

     LUN Group Device RAID Capacity Status
                         Name Level (MB)

      0 1 c1t5d0 1 34692 Optimal
      1 1 c1t5d1 1 34692 Optimal
      2 1 c1t5d2 1 34692 Optimal
      3 2 c1t5d3 1 34692 Optimal
      4 3 c1t5d4 0 34692 Optimal
      5 4 c1t5d5 0 34692 Optimal

    drivutil succeeded!
    #

    Which would seem to indicate that is is 'ok' for now

    My question is this.
    I have a 'spare' drive as a backup. Should I go ahead and replace it?
    If so, since the drive is in the c1t5d3 device in a RAID1 config, can I just
    pull the drive with the yellow LED and it will rebuild automatically?
    Or is there something else I need to do first, next, last

    I would rather replace it now if it is going to ultimately fail, but I have
    an Oracle database on that device so don't know whether I
    should shut it down or what before replacing the drive.

    Any advice appreciated.

    Thanks
    alan
