HSG80 Controller Failover Transitions
109Secure Path v3.0C for Linux and Linux Workgroup Edition Installation and Reference Guide
After both controllers have restarted, the controller pair will be bound in
Multiple-bus Failover mode with consistent views of all the RAID array
information.
5. Verify that the controllers are now in Multiple-bus Failover:
CLI> show this_controller
6. If the RAID array had connections prior to making this transition, examine the
connections by entering the following command:
CLI> show connections
7. Inspect the last column, offset value, by entering the following
command.
CLI> set connection
connection_name
unit_offset=0
Note: In Transparent Failover mode, the controller, by default, assigns an offset value
of 0 to the left-hand port and an offset value of 100 to the right-hand port. In
Multiple-bus Failover mode, the controller assigns an offset value of 0 to all ports,
unless existing connections have nonzero offset values.
