a. If the controllers are in Transparent Failover Mode (see line 6 of
example controller output) then they must be reconfigured for
multiple-bus failover. Configure the RAID system controllers for
multiple-bus failover mode, using the commands below.
HSG80> set nofailover
HSG80 > set multibus_failover copy = this_controller
The controllers will restart in multiple-bus mode. After the other
controller has restarted, verify that both controllers are configured for
multiple-bus mode by issuing the following commands:
HSG80 > show this_controller
HSG80> show other_controller
Line 6 of the controller output should be similar to the following
(ignoring the value of the serial number):
Configured for MULTIBUS_FAILOVER with ZG90811309
b. Set the Preferred Path for each storage unit to specify the controller
that the unit will use upon the RAID system boot time as follows:
First, enter the following command to obtain a list of all units defined in
the RAID system:
HSG80 > show units full
An example of the “show units” output follows:
