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 6–3, you could choose the following device names when setting the bootdef_dev console environment variable:

dga133.1001.0.1.0 1

dga133.1004.0.1.0 2

dgb133.1002.0.2.0 3

dgb133.1003.0.2.0 4

Path from host bus adapter A to controller B port 2

Path from host bus adapter A to controller A port 1

Path from host bus adapter B to controller A port 2

Path from host bus adapter B to controller B port 1

You can set units preferred to a specific controller, in which case both controllers will be active.

3.Set the bootdef_dev console environment variable to a comma separated list of several of the boot path(s) that show up as connected in the reachability display (wwidmgr -quicksetor wwidmgr -show reachability). You must initialize the system to use any of the device names in the bootdef_dev variable as follows:

•For the base operating system:

P00>>> set bootdef_dev \ dga133.1001.0.1.0,dga133.1002.0.2.0,\ dgb133.1001.0.1.0,dgb133.1002.0.2.0

POO>>> init

•For member system 1 boot disk:

P00>>> set bootdef_dev \ dga131.1001.0.1.0,dga131.1002.0.2.0,\ dgb131.1001.0.1.0,dgb131.1002.0.2.0
