Important
If you want to use the controller failover feature for RIMs or F-QIPs (see Configure
Controller Failover on page 128), keep the following requirements in mind:
 You must have two controllers (RIMs or F-QIPs) installed in the library.
 If the partition uses SCSI drives, you cannot use the F-QIP that provides
connectivity for the SCSI drives in the failover pair. A minimum of three
controllers are required for this type of configuration.
 If you configured controller failover before you configured the storage partition,
select the primary controller in the failover pair to provide the robotic control path.
Important
Do not select more than one drive to provide the robotic control path unless you
know the storage management software can support this.
Important
If you select two different generations of drives to provide the robotic control path,
then you are not able to assign a Global Spare to the partition because all of the
drives in a partition with a Global Spare must match the technology generation of
the Global Spare.
