Meaning
Disk Enclosure Power 1

Disk Enclosure Fault
1
Amber On when any fault condition exists; if the fault is not obvious
from a disk module light, look at the back of the disk enclosure.
Disk Active
1 per disk module
Green
Off when the slot is empty or contains a filler module.
Also off when the disk is powered down by command; for
example, the result of a temperature fault.
Flashing
(mostly off) when the FC drive is powered up but not
spinning; this is a normal part of the spin
-
up sequence,
occurring during the spin-up delay of a slot.
Flashing
(at a constant rate)
FC drive: when the drive is spinning up or spinning down
normally.
ATA drive: when the module has received power but the disk
has not started spinning
On when the drive has power but is not handling any I/O activity
(the ready state). ATA modules also show the Disk Active LED
on while the disk spins up or down normally.
Flashing
(mostly on) when the drive is spinning and handling I/O
activity.
Flashing (constant fast rate) when an ATA LCC has forced
ownership of the drive.
Disk Fault
1 per disk module
Amber On when the disk module is faulty, or as an indication to remove
the drive.
