6.6.2 Install the Tru64 UNIX Operating System
After reading the TruCluster Server Software Installation manual, and
using the Tru64 UNIX Installation Guide as a reference, boot from the
CD-ROM and install the Tru64 UNIX Version 5.1 operating system.
When the installation procedure displays the list of disks available for
operating system installation as shown here, look for the identifier in
the Location column. Verify the identifier from the table you have been
preparing (see Table 6–2).
To visually locate a disk, enter "ping <disk>",
where <disk> is the device name (for example, dsk0) of the disk you
want to locate. If that disk has a visible indicator light, it will
blink until you are ready to continue.
Device Size Controller Disk
Name in GB Type Model Location
1) dsk0 4.0 SCSI RZ2CA-LA bus-0-targ-0-lun-0
2) dsk15 1.0 SCSI HSG80 IDENTIFIER=133
3) dsk17 2.0 SCSI HSG80 IDENTIFIER=131
If you flash the light on a storage unit (logical disk) that is a mirrorset,
stripeset, or RAIDset, the lights on all disks in the storageset will blink.
Record the /dev/disk/dskn value (dsk15) for the Tru64 UNIX disk that
matches the UDID (133) (Table 6–2).
Complete the installation, following the instructions in the Tru64 UNIX
Installation Guide.
6.6.3 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 5.1 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. Pipe the
command through the grep utility to search for any items with the
IDENTIFIER qualifier.
# hwmgr -view dev | grep IDENTIFIER
HWID: Device Name Mfg Model Location
