4.4.3 RTCL BOARD ON DISK ARRAY (WITH HCTX)
Disk Arrays on systems with HCTX Boards have a controller on the disk
array board.
4.4.3.1 LEDS
0/A – 1/B – 2/C – 3/D – 4/E (between the 2
nd
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
• 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 are transferred between the RAID array and the HCT-X board. If
the led is nearly permanently on, it means that data are transferred almost all the time
between the RAID array and the HCT-X board, thus being close to the max. bandwidth
of the system.
STS
(between the 1st and 2
nd
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.
