Configure Controller Failover
Overview The library supports using two RIMs or F-QIPs to provide a
redundant connection to the robotics. A single controller can be configured
as the failover controller for multiple partitions. See Controller Failover on
page 70 for information about how controller failover functions.
To use the controller failover feature, you must assign a failover partner to
the controller you selected to provide the partition’s robotic control path to
the robotics.
Notes: RIMs and F-QIPs can be mixed in a failover pair; a RIM2 can
only be in a failover pair with another RIM2.
Drives used to provide the robotic control path cannot be
configured with controller failover, however, if you are using
LTO-5 and later generation tape drives, you can export the
same changer interface over multiple drives in the partition
to provide redundancy as long as your software can support
this. You cannot use multiple paths at the same time.
If desired, you can configure multiple RIMs for the same
partition and export the same changer interface over them to
provide redundancy as long as your software can support
this.
The Controller Failover feature is not supported for any
F-QIP that is connected to SCSI drives. The F-QIP pair
configured for Controller Failover can only be used to
provide the robotic control path.
Controller failover is not supported on 4 Gb/second F-QIPs.
If you have 4 Gb/second Fibre Channel F-QIPs, the Failover
button does not display on the Controllers screen.
Note: If you configure controller failover before you create storage
partitions, the secondary controller in the failover pair is not
available for use as the exporting controller for the partitions.
User Privilege Requirements Only a user with superuser or administrator
privileges can configure controller failover. See Understanding User
Groups and Security on page 96 for information about the three types of
user groups and what types of privileges each has.
