Changing from Multiple-bus Failover mode to no failover and

then to Transparent Failover mode

1. Check for connections on the storage system. For HSG80 controllers, enter

the following command:

CLI> show connections

2. Delete all connections by entering the following command for each

connection that is shown (if any):

CLI> delete

connection_name

Note: The connections will be regenerated later.

3. Check for units on the storage system:

CLI> show units

4. Delete all units by entering the following command for each unit (Dn) that is

shown (if any):

CLI> delete

Note: The UNITs will be restored after the controller state is changed. HP recommends

that you record Dn values and associated information, as well as the storageset

information, for later use. The controller state change will not affect the data on the

storagesets.

5. If the controllers are currently in a failover mode, enter the following

command to shut down the OTHER_CONTROLLER:

CLI> set nofailover

6. Verify the current state of the controller, by entering the following command:

CLI> show this_controller
