b.Set the bootdef_dev console environment variable to one reachable path (Yes in the connected column) to the member system boot disk (See Section 6.6.3):

P00>>> set bootdef_dev dga132.1002.0.1.0

c.Boot genvmunix on the newly added cluster member system.

5.After the new kernel is built, do not reboot the new cluster member system. Shut down the system and reset the bootdef_dev console environment variable to provide multiple boot paths to the member system boot disk before booting (see Section 6.8).

6.Repeat steps 4 and 5 for other cluster member systems.

6.11Changing the HSG80 from Transparent to Multiple-Bus Failover Mode

You may be are using transparent failover mode with Tru64 UNIX Version 5.0A and TruCluster Server Version 5.0A and want to take advantage of the ability to create a no-single-point-of-failure (NSPOF) configuration, and the availability that multiple-bus failover provides over transparent failover mode.

If you are upgrading from Tru64 UNIX Version 4.0F or Version 4.0G and TruCluster Software Products Version 1.6 to Tru64 UNIX Version 5.0A and TruCluster Server Version 5.0A you may want to change from transparent failover to multiple-bus failover to take advantage of multibus support in Tru64 UNIX Version 5.0A and multiple-bus failover mode and the ability to create a NSPOF cluster.

The change in failover modes cannot be accomplished with a simple SET MULTIBUS COPY=THIS HSG80 CLI command because:

•Unit offsets are not changed by the HSG80 SET MULTIBUS_FAILOVER COPY=THIS command.
