1.5Identifying Drives

Assuming there is a failed drive in the RAID 5 logical drive, make it a point to replace the failed drive with a new, healthy drive to keep the logical drive working.

If, when trying to remove a failed drive you mistakenly remove the wrong drive, you will no longer be able to access the logical drive because you have inadequately failed another drive.

To prevent this from happening, the controller provides an easy way to identify the faulty drive. By forcing certain drive LEDs to light for a configurable period of time, the faulty drive can be identified, and thus reducing the chance of removing the wrong drive. This function is especially helpful in an installation site operating with hundreds of drives.

R/W LED
	Flash Selected SCSI Drive
R/W LED	The Read/Write LED of the drive you selected will light steadily
	for a configurable period of time, from 1 to 999 seconds.
LED Steadily ON

R/W LED	Flash All SCSI Drives
	The Read/Write LEDs of all connected drives will	LED Steadily ON
R/W LED	light for a configurable period of time. If the LED of
	the defective drive did not light on the “Flash
	Selected SCSI Drive” function, use “Flash All SCSI	LED Steadily ON
	Drives” to verify the fault. If the “Flash All SCSI
	Drives” function is executed, and the defective drive’s	LED Steadily ON
	LED still does not respond, it can be a drive tray
	problem or the drive is dead.	LED Steadily ON
L E D
		LED Steadily ON
L E D	Flash All but Selected Drives
L E D	Except the selected drive, the Read/Write LEDs of all
	connected drives will light for a configurable period of time ranging
R /W
	from 1 to 999 seconds. If an administrator can not be sure of the
L E D	exact location of specific drive, this function will help to indicate
	where it is. This can prevent removal of the wrong drive when a
L E D	drive fails and is about to be replaced.
	The drive identifying function can be selected from “Main
	Menu”/”View and Edit SCSI Drives”/”Identify SCSI Drives.”
