Identifying 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.
