The drive has failed, or a predictive failure alert has
been received for this drive; it also has been selected
by a management application.
Alternating amber and blueOn, off, or flashing
The drive is operating normally, and it has been
selected by a management application.
Steadily blueOn, off, or flashing
A predictive failure alert has been received for this
drive.
Amber, flashing regularly (1 Hz)On
Replace the drive as soon as possible.
The drive is online, but it is not currently active.OffOn
CAUTION: Do not remove the drive. Removing a
drive may terminate the current operation and cause
data loss.
Amber, flashing regularly (1 Hz)Flashing regularly (1 Hz)
The drive is part of an array that is undergoing
capacity expansion or a stripe size migration, but a
predictive failure alert has been received for this
drive. To minimize the risk of data loss, do not replace
the drive until the expansion or migration is complete.
CAUTION: Do not remove the drive. Removing a
drive may terminate the current operation and cause
data loss.
OffFlashing regularly (1 Hz)
The drive is rebuilding, or it is part of an array that is
undergoing array expansion, logical drive extension,
a stripe size migration, or RAID migration.
The drive is active, but a predictive failure alert has
been received for this drive. Replace the drive as
soon as possible.
Amber, flashing regularly (1 Hz)Flashing irregularly
The drive is active and operating normally.OffFlashing irregularly
A critical fault condition has been identified for this
drive, and the controller has placed it offline. Replace
the drive as soon as possible.
