LEDs
0/A – 1/B – 2/C – 3/D – 4/E (between the 2nd and 3rd disk from left in front):
These LEDs match the position of the disks on the board, i.e:
0/A
RCTL 3/D
1/B
2/C 4/E
Disk LEDs
off the corresponding disk is not started (not spinning).
on, fast blinking
(green)
the corresponding disk is starting (spinning).
on, steady (green) the corresponding disk is started and used in the RAID
array.
on, slowly blinking
(green)
the corresponding disk is started but not used in the RAID
array.
TF (just behind the 5 disks LEDs) :
on (green) when data is transferred between the RAID array and the HCTX
board.
If the led is nearly permanently on, it means that data is
transferred almost all the time between the RAID array and the
HCTX board, thus being close to the max. bandwidth of the
system.
STS (between the 1st and 2nd disk from left in front) :
on (green) when RCTL RAID controller is properly booted.
ERR (next to STS) :
lights red when errors occur during the data transfer between the RAID
controller and the disks
