Building an HA Cluster Configuration

Preparing Your Systems

Chapter 5216

Step 1. Use a text editor to create a file that contains the partition information.

You need to create at least three partitions, for example:

EFI 100MB

HPUX 1MB

HPUX 100%

This defines:

• A 100 MB EFI (Extensible Firmware Interface) partition (this is

required)

• A 1 MB partition that can be used for the lock LUN

• A third partition that consumes the remainder of the disk is and can

be used for whatever purpose you like.

Step 2. Save the file; for example you might call it partition.txt.

Step 3. Create the partition; for example (using partition.txt as input):

/usr/sbin/idisk -w -p -f partition.txt /dev/rdsk/c1t4d0

Or, on an HP-UX 11i v3 system using agile addressing (see “About

Device File Names (Device Special Files)” on page 111:

/usr/sbin/idisk -w -p -f partition.txt /dev/rdisk/disk12

This will create three device files, for example

/dev/dsk/c1t4d0s1, /dev/dsk/c1t4d0s2, and /dev/dsk/c1t4d0s3

or:

/dev/disk/disk12_p1, /dev/disk/disk12_p2, and

/dev/disk/disk12_p3

NOTE The first partition, identified by the device file /dev/dsk/c1t4d0s1 or

/dev/disk/disk12_p1 in this example, is reserved by EFI and cannot be

used for any other purpose.

Step 4. Create the device files on the other cluster nodes.
