Technical data

For more information on using the ffauto and ffnext
console environment variables, see the wwidmgr User’s
Manual.
2. Set the bootdef_dev console environment variable for the base
operating system boot disk to a comma-separated list of several of the
boot paths that show up in the reachability display (wwidmgr -show
reachability). You must initialize the system to use any of the device
names in the bootdef_dev variable as follows:
P00>>> set bootdef_dev \
dga101.1001.0.7.0, dga101.1002.0.7.0, \
dgb101.1001.0.8.0, dgb101.1002.0.8.0
POO>>> init
______________________ Note _______________________
The console SystemReference Manual (SRM) software guarantees
that you can set the bootdef_dev console environment variable
to a minimum of four device names. You may be able to set it to
five, but only four are guaranteed.
4.10.3 Determining /dev/disk/dskn to Use for a Cluster Installation
Before installing the TruCluster Server software, you must determine which
/dev/disk/dskn to use for the various TruCluster Server disks.
To determine the /dev/disk/dskn to use for the cluster disks, follow these
steps:
1. On the system where you installed the Tru64 UNIX operating system, if
you have not already done so, boot the system. With the Tru64 UNIX
operating system at single-user or multi-user mode, use the hardware
manager utility (hwmgr) with the view devices option to display all
devices on the system. Pipe the command through the grep utility to
search for any items with the IDENTIFIER or MSA1000 qualifiers, as
shown in Example 4-21 or Example 4-22.
