Select the Robotic Control Path
Controllers in the library are used to provide the robotic control path for
the partition. The controller “exports” the partition to the hosts, receiving
and processing the robotic motion commands sent from the host to move
tapes. RIMs, F-QIPs, and LTO tape drives can act as controllers.
Notes:  A RIM is identified as an F-QIP in the Robotic Control Path
screen and other screens that reference controllers. See RIM
and F-QIP Identifiers on page 57 for additional information
about the RIM identifier.
 You can select multiple similar exporting controllers
(F-QIPs/RIMs, or drives), and export the same changer
interface over them to provide redundancy, as long as your
storage management software can support this. You cannot
use multiple paths at the same time.
 If a partition uses multiple exporting controllers, the
partition cannot use QuickScan.
 If you are using LTO-5 and later generation drives, you can
select multiple drives as controllers, and export the same
changer interface over the drives to provide redundancy, as
long as your software can support this. These multiple paths
cannot be used at the same time. Assigning multiple drive
exporters to one partition reduces the total number of
partitions that can be configured in the library.
 Starting with BlueScale12.7.05, the maximum number of
exporters supported by the library is six.
 Six drive exporters can be used for six different partitions,
or multiple exporters can be configured in the same
partition, reducing the maximum number of partitions.
 A single RIM can export up to eight partitions, but still
only count as one exporter; a single RIM2 can export up to
16 partitions, but still only count as one exporter.
 A TS11xx technology drive cannot provide the robotic
control path. TS11xx technology partitions must use a RIM.
 The library does not support selecting drives and a RIM or
F-QIP to export the partition.
Important
When you select a RIM as the controller, you must use direct-attached drives in the
partition. The RIM does not provide drive connectivity.
