To set the bootdef_dev console environment variable for the Tru64 UNIX
installation when booting from a Fibre Channel device, follow these steps:
1. Obtain the device name for the Fibre Channel storage unit where you
will install the Tru64 UNIX operating system. The device name shows
up in the reachability display as shown in Example 6–5 with a Yes
under the connected column. You can also use the wwidmgr -show
reachability command to determine reachability. Example 6–6
provides the display for a show dev command, which shows the device
names of devices that may be assigned to the bootdef_dev console
environment variable. Example 6–5 and Example 6–6 show that the
following device names can be used in the bootdef_dev console
environment variable as possible boot devices:
• dga131.1002.0.1.0
• dga131.1004.0.1.0
• dga133.1002.0.1.0
• dga133.1004.0.1.0
• dgb131.1002.0.2.0
• dgb131.1004.0.2.0
• dgb133.1002.0.2.0
• dgb133.1004.0.2.0
Each of the storage units are reachable through four different paths,
two for each host bus adapter (the Yes in the connected column).
2. Set the bootdef_dev console environment variable to one of the boot
path(s) that show up as connected to the disk you will use for the Tru64
UNIX installation. For the example disk configuration on the system
where you are installing the Tru64 UNIX operating system (which will
eventually be the first cluster member), set bootdef_dev as follows:
P00>>> set bootdef_dev dga133.1002.0.1.0
3. You must initialize the system to use any of the device names in the
bootdef_dev variable:
P00>>> init
.
.
.
After the initialization, the bootdef_dev will show up as follows:
P00>>> show bootdef_dev
bootdef_dev dga133.1002.0.1.0
You are now ready to install the Tru64 UNIX operating system.
