Note: Your information might be different from that shown in
this screen.
The Logical Drive list contains the logical drive ID, the size in
megabytes of each logical drive, the RAID level you assigned to
that logical drive, and the date you created it.
The status of the logical drive is also shown. OKY means that
no problem conditions are associated with the drive; CRT
means that you must replace the hard disk drive and rebuild the
logical drive. (You will have received a message telling you
what has happened to the drive.) OFL means that the logical
drive is unrecoverable; the data in that drive is lost.
