Drive Status LEDs

The Light-Emitting Diodes (LEDs) on the front of the disk drive section help you determine
disk drive status at a glance. There are two LEDs for each disk drive, making a total of eight
drive status LEDs. The eight drive status LEDs, which display through the window of the disk
drive door, indicate the activity or status for each of the installed drives.
For SCSI disk drives, only the left drive status LED of each drive status LED pair lights. The
left LED for each disk drive flashes to show disk activity.
RAID systems are equipped with a SCSI Activity Fault-Tolerant Enclosure (SAF-TE) card
which monitors the status of the RAID disk drives. The SAF-TE card provides an interface
between the SCSI backplane and the RAID controller, and causes the right drive status LED
of each LED pair to flash according to the drive status. The right drive status LED lights
differently depending on the RAID drive status, as shown in the following table:
Right LED Activity
Off
Steady On
Steady Blink (approx. 1 per second)
Steady Blink (approx. 3 per second)
4 Fast Blinks, Pause (repeats)
2 Fast Blinks, Pause (repeats)
To administer the RAID disk drives and the SAF-TE card, use the Mylex RAID configuration
utility as described in the Mylex RAID controller documentation delivered with the system.
