RAID Technology
drive in Channel 2, Bay 1, has a drive status of ONL and is a
part of Array B. Selections are made from this list to determine
which bays (hard disk drives) are in your arrays.
Notes:
The Bay/Array area on the screen does not reflect the
physical configuration of the server. In your server,
the default numbering for the hard disk drive bays in
each bank is 1 through 6 (from left to right). See
“Installing Internal Drives” on page 212 to see the
physical location of the hard disk drives.
The IDs for the hot-swappable drives are set by the
backplanes. This allows you to define the IDs as low
(0 to 5) or high (8 to 13). See “Setting Backplane SCSI
ID Jumpers (J12)” on page 274 for information on
setting the jumpers on the backplanes.
One channel on the ServeRAID adapter can support
two daisy-chained banks of bays. The SCSI ID
jumpers on the backplanes must be set to avoid SCSI
ID conflicts.
The Bay Number corresponds to the SCSI ID of the
device plus 1. When the SCSI IDs are set to high, the
hard disk drive with SCSI ID 8 is installed in the
leftmost bay; its status displays in Bay Number 9.
4. The Array list indicates the array ID and the size (in megabytes)
of the array. When a drive is being rebuilt, this area, along with
the Logical Drive list area, shows the progression of the
rebuilding process.
5. The Logical Drive list identifies the logical drive (for example,
A1), including its size, the RAID level, date of creation, and its
write policy.
The status of the logical drive also is shown. OKY means that
no problem conditions are associated with the drive. CRT
means that you must replace the defunct drive and do a rebuild
operation. (You will have received a message telling you what
has happened to the drive.) OFL means that the logical drive is
irrecoverable; the data in that drive is lost.
