6.7.2Procedure to Convert from Transparent to Multiple-bus Failover Mode

To change from transparent failover to multiple-bus failover mode by resetting the unit offsets and modifying the systems’ view of the storage units, follow these steps:

1.Shut down the operating systems on all host systems that are accessing the HSG80 controllers you want to change from transparent failover to multiple-bus failover mode.

2.At the HSG80, set multiple-bus failover as follows. Note that before putting the controllers in multiple-bus failover mode, you must remove any previous failover mode:

HSG80> SET NOFAILOVER

HSG80> SET MULTIBUS_FAILOVER COPY=THIS

____________________ Note _____________________

Use the controller known to have the good configuration information.

3.Execute the SHOW CONNECTION command to determine which connections have a nonzero offset as follows:

HSG80> SHOW CONNECTION
Connection						Unit
