Compaq Hot-Plug Ultra2 and Ultra3 SCSI
Hard Drive LED Indicators
There are three LED indicators on the Ultra2 and Ultra3 SCSI hard drives.
During the shared storage area initial power up all the LED indicators (
, ,
and
) on the hard drives turn on. LED indicators and remain lit until the
Power-On Self-Test (POST) of the CR3500 RAID Controller completes.
During initialization, the activity LED of a drive will blink as being accessed
by the CR3500 RAID Controller. After the CR3500 RAID Controller
initializes, the LED indicators that remain lit on the hard drives is dependent
on the RAID configuration. If they are part of a RAID 0+1, 1, 4, or 5, then the
fault LED
turns Off and the online LED remains lit. If the hard drives are
not part of a RAID set (JBOD, spare, or unconfigured), then all the LED
indicators turn Off. If the fault LED remains lit after initialization, the drive
has failed. The following figure shows the location of the status LED
indicators on a Compaq hot-plug Ultra2 and Ultra3 SCSI hard drive.
