Determining /Dev/Disk/Dskn To Use For A Cluster Installation - Compaq TruCluster Server AA-RHGWB-TE Manual

• For member system 2 boot disk:
P00>>> set bootdef_dev \
dga132.1001.0.1.0,dga132.1002.0.2.0,\

POO>>> init
______________________
The console system reference 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 four is all that is guaranteed.
6.9 Determining /dev/disk/dskn to Use for a Cluster
Installation
Before you can install 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. With the Tru64 UNIX Version 5.0A operating system at single-user or
multi-user mode, use the hardware manager (hwmgr) utility with the
-view devices option to display all devices on the system. Use the
grep utility to search for any items with the IDENTIFIER qualifier.
# hwmgr -view dev | grep IDENTIFIER
HWID: Device Name
-----------------------------------------------------------------------
62: /dev/disk/dsk15c
63: /dev/disk/dsk16c
64: /dev/disk/dsk17c
65: /dev/disk/dsk18c
66: /dev/disk/dsk19c
67: /dev/disk/dsk20c
68: /dev/disk/dsk21c
____________________
If you know that you have set the UDID for a large number
of disks, you can also grep for the UDID:
# hwmgr -view dev | grep IDENTIFIER | grep 131
If you have not set the UDID, you can use hwmgr to determine
the /dev/disk/dskn name by using the hardware manager
to display device attributes and searching for the storage
unit worldwide name as follows:
