7.11.3 Identifying Drives
Fig. 7.47 Identify Drive Page
Whenever there is a failed drive in a logical drive, make it a point to replace the failed drive
with a new, healthy drive to keep the logical drive working.
If you replaced the wrong drive when trying to replace a failed drive you will no longer be able
to access the logical drive because you have inadvertently 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 reduce the chance of removing the wrong drive. This function can
be especially helpful in an installation site operating with hundreds of drives.
Flash Selected Drive
The Read/Write LED of the drive you selected will light steadily for a configurable period of
time, from 1 to 999 seconds.
Fig. 7.48 Flash Selected Drive
Flash All Drives
The Read/Write LEDs of all connected drives will light for a configurable period of time. If the
LED of the defective drive did not light on the “Flash Selected Drive” function, use “Flash All
Drives” to verify the fault. If the “Flash All Drives” function is executed, and the defective
drive’s LED still does not respond, it can be a drive tray problem or the drive is dead.
