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
dga133.1004.0.1.0
dgb133.1002.0.2.0
dgb133.1003.0.2.0
Path from host bus adapter A to controller B port 2
1
Path from host bus adapter A to controller A port 1
2
Path from host bus adapter B to controller A port 2
3
Path from host bus adapter B to controller B port 1
4
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 -quickset or 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
POO>>> init
