Disk
icons indicate the disk’s type and state:
Disk not present
: A grayed out icon with a grayed out status bar indicates that no
drive is installed in that slot.
Disk not configured
: A gray status bar indicates that the drive is functioning, but is
not assigned to an array and is not designated as a spare.
Array disk, functioning normally
: A green status bar indicates that the drive is
functioning and is part of a RAID array (see
on page 63). The
text below it indicates which RAID array it belongs to and which RAID Controller
owns that array.
Spare disk
: A blue status bar indicates that the drive is functioning and is designated
as a spare, which will be used to rebuild RAID arrays when other drives fail (see
on page 128, and
on page 132). The text below it indicates whether it is a “Pool Spare” (which
can be used by any RAID array) or a dedicated spare (assigned to a specific RAID
array).
Disk idle
: A green “Zzz” on a disk icon indicates that the drive is in low-power mode
(see
on page 181). This does not apply to SSD disks.
Disk inaccessible
: A red status bar indicates that the drive is functioning, but the
RAID array to which it belongs is currently inaccessible.
Disk in critical array
: A status bar alternating amber and red indicates that the drive
is functioning, but is part of a RAID array that is in a critical state (see
Disk failed
: A red icon with a flashing red status bar indicates that the drive has
failed.
Spare added to array
: A “filling” green status bar indicates that this disk was a
spare, but is being added to the array. Data from the missing drive is being rebuilt and
saved onto this disk.
Disk being retired
: An “emptying” green status bar indicates that this disk is being
retired. Data from this drive is being rebuilt and saved onto a spare disk.
Disk retired
: A flashing red status bar indicates that the disk has been retired. A
retired disk cannot be added to an array or added as a spare disk.
Array rebuilding
: A status bar alternating green and amber indicates that the drive
is functioning and is part of a RAID array that is being rebuilt.
Disk locked
: An orange icon with a flashing red status bar indicates that the drive is
locked and cannot be used. Locked disks are disks that previously belonged to an
encrypted array (see
on page 120), but that were moved
from one unit to another without first being decrypted. Uploading the proper
encryption key unlocks the disks. Access to the drives can be restored by uploading
the exported encryption key file(s). See
