Setting an ESS volume as a boot device
All cluster member boot partitions must exist on shared external storage.
Non-cluster boot partitions might also exist on external storage.
Perform the following steps to set an ESS volume as a boot device.
1. Determine which ESS volume you want to use as a boot device for each host
by decoding the serial number.
Use the -item form of the wwidmgr -quickset command to assign a device unit
number to an ESS volume.
See Figure 24 for an example of how to assign a device unit number.
Note: You cannot use the -UDID form of the command because you cannot
assign the UDID to an ESS volume.
The wwidn and nn values are defined automatically. There are multiple paths to
the ESS boot device.
2. Assign one of the paths to the bootdefdev AlphaServer console value.
3. For initial installations, install the operating system and clustering software and
register the operating system and clustering licenses.
