drive in Channel 1, Bay 1 has a drive state of online
(ONL) and is part of Array A.
Notes
1. The Array/Bay selection list does not reflect
the physical configuration of the server.
(See “Internal drive bays” on page 197 for
the physical location of the hard disk
drives.)
2. The SCSI IDs for the hot-swap hard disk
drives is set by the backplane. The
backplane allows you to define the IDs as
low (0 to 5) or high (8 to 13). See “SCSI
backplane option jumpers” on page 250 for
more information about setting jumpers on
the backplane.
3. The bay number corresponds to the SCSI
ID of the device plus 1. For example, the
ServeRAID controller (INI) uses SCSI ID 7
and its bay number is 8 (7
+
1).
4. Bay Number 8 (SCSI ID 7) is reserved for
the ServeRAID controller (also known as
the initiator, INI); therefore do not set the
SCSI ID of non-hot-swap device, such as a
tape drive, to 7.

The Array list indicates the array IDs and the sizes
(in megabytes) of the arrays. When a drive is being
rebuilt, this list and the Logical Drive list show the
progression of the rebuild process.
5
The Logical Drive list shows the size, RAID level,
status, and write policy for each logical drive. (See
“Logical drive states” on page 88 for more
information.)

This area provides information and instructions
about the actions you can perform on the current
screen or pop-up window.
Physical device states:
Descriptions of the physical
device states, which appear in the Array/Bay selection list,
are as follows:
State Meaning
CDR A CD-ROM drive is installed.
DDD The physical hard disk drive is defunct (DDD).
A drive in the Online (ONL) or Rebuild (RBL)
state has become defunct (DDD). It does not
respond to commands, which means that the
ServeRAID controller cannot communicate
properly with the drive.
A hard disk drive in the DDD state does not
necessarily mean that you need to replace the
