The member drive can be physically identified, in its
enclosure, by right-clicking in the Attached Drives list
and selecting Locate (See
Exhibit 1.5.1--20 below).
The drive's Identify LED (or activity LED, in a non-SES
enclosure) should blink.
Sometimes the activity LED won't blink because of a
failure in the drive or enclosure electronics. One
possible action is to blink all the other LEDs, and find
the failed drive by process of elimination.

RAID Group goes OFFLINE
When a drive fails, but the wrong drive is replaced, a
rebuild will not initiate and the RAID Group will be
taken off line. The user should follow the procedure
described earlier in this section to identify the failed
drive, and ensure the correct drive is replaced.
The situation described above can be
corrected.Replace the erroneously replaced drive (3A)
with the original drive 3 in the above example; then
identify and replace the failed drive (4); and then start
a rebuild.
