Compaq AA-RHGWC-TE manual P00 set bootdefdev dga132.1002.0.1.0

b.Set the bootdef_dev console environment variable to one reachable path (Yes in the connected column of Example 6–7) to the member system boot disk:

P00>>> set bootdef_dev dga132.1002.0.1.0

c.Boot genvmunix on the newly added cluster member system. Each installed subset will be configured and a new kernel will be built and installed. After the new kernel is built, do not reboot the new cluster member system.

2.Shut down the system and reset the bootdef_dev console environment variable to provide multiple boot paths to the member system boot disk as follows:

a.Obtain the device name and worldwide name for the Fibre Channel unit from where you will boot (see Table 6–2). Ensure that you choose the correct device name for the entity you are booting (cluster member system 2, cluster member system 3, and so on).

b.Check the reachability display (Example 6–7) provided by the wwidmgr -quicksetcommand for the device names that can access the storage unit from where you are booting. Check the show dev command output to ensure the device name may be assigned to the bootdef_dev console environment variable.

_________________ Notes __________________

You should choose device names that show up as both Yes and No in the reachability display connected column. Keep in mind, that for multiple-bus failover, only one controller is normally active for a storage unit. You must ensure that the unit is reachable if the controllers have failed over.

If you have multiple Fibre Channel host bus adapters, you should use device names for at least two host bus adapters.

For example, to ensure that you have a connected boot path in case of a failed host bus adapter or controller failover, choose device names for multiple host bus adapters and each controller port. For example, if you use the reachability display shown in Example 6–7, you could choose the following device names when setting the bootdef_dev console environment variable for the second cluster member system:
