RIM and F-QIP Identifiers
RIMs and F-QIPs can be installed in any controller bay in the library. The
component identifier for a RIM or F-QIP is based on the drive bay assembly
(DBA) in which it is installed.
The component identifier for a RIM or F-QIP is shown as DBA
x
/F-QIP
n
,
where:
DBA
x
is the number of the DBA where the RIM or F-QIP is installed (see
Figure 20 on page 56).
F-QIP
n
is the interface type (Fibre Channel) of the RIM or F-QIP and the
number of the controller bay where it is installed. Because each DBA
contains only one controller bay, n is always 1.
Note: The component identifier for a RIM shows it as an F-QIP. For
example, Figure 21 shows the component identifier for the RIM
installed in DBA 1 DBA1/F-QIP1) on the Controllers screen. The
device descriptor (2-Gbps FC RIM) indicates that the controller is
a RIM.
Drive Identifiers
The firmware in the drive sled that houses each drive assigns an identifier
to the drive based on its location in the library. This identifier is shown in
the BlueScale user interface and is used in the XML command interface.
The identifier is also used to generate the World Wide Name (WWN) that
the library reports for the drive (see World Wide Names for Fibre Channel
Partitions on page 63). Because the identifier is location-based, it remains
constant even if the physical drive is replaced by a new drive. The new
drive assumes the location-based identifier.

component identifier for a RIM.
