Note –
If a disk drive is under an unusually heavy load (for example, if the drive is
being reformatted), the Disk Drive LED might be unlit for a long period of time,
even though the drive has not failed. You should see a message in your console
window telling you that the disk drive is offline if the disk drive has truly failed.

To Check the Binary SCSI ID LED Display
Check the binary SCSI LED display to confirm that the SCSI IDs are set correctly or
to determine which SCSI IDs are assigned to which disk drives.
1. Remove the front bezel by pressing the latches on both ends and pulling the bezel
away from the enclosure.
Flashing green A hard drive is present in that
slot and is active. No action is necessary.
Unlit No hard drive is present in that
slot, or the disk drive has
failed. If the power is on, a hard drive
is present in that slot, and the
hard drive LED is unlit, then
you must replace the hard
drive. See “Removing and
Replacing a Hard Disk Drive”
on page 62.
Binary SCSI LEDs Solid green (in
various
combinations) The position of the binary
display indicates the base
number (first number) of the
three drive sequence. See the
pull-out card or “To Check the
Binary SCSI ID LED Display”
on page 69. No action is necessary.
