Mirroring the Root Volume on Integrity Servers

The procedure to mirror the root disk on Integrity servers is similar to the procedure for PA-RISC

servers. The difference is that Integrity server boot disks are partitioned; you must set up the partitions,

copy utilities to the EFI partition, and use the HP-UX partition device files for LVM commands.

For this example, the disk is at hardware path 0/1/1/0.1.0, with a device special file named

/dev/rdsk/c2t1d0.

1. Partition the disk by using the idisk command and a partition description file.

First, clear the previous partition configuration on the disk:

# idisk –Rw /dev/rdsk/c2t1d0

a. Create a partition description file. For example:

# vi /tmp/pdf

In this example, the partition description file contains:

EFI 500MB

HPUX 100%

HPSP 400MB

b. Partition the disk using idisk and the partition description file created in step 1a:

# idisk -f /tmp/pdf -w /dev/rdsk/c2t1d0

To verify that your partitions are correctly laid out, enter the following command:

# idisk /dev/rdsk/c2t1d0

2. Enter the insf command with the -e option to create the legacy device files for all the partitions:

# insf -e -H 0/1/1/0.1.0

You now have the following device files for this disk:

/dev/dsk/c2t1d0

The entire disk (block access)

/dev/rdsk/c2t1d0

The entire disk (character access)

/dev/dsk/c2t1d0s1

The EFI partition (block access)

/dev/rdsk/c2t1d0s1

The EFI partition (character access)

/dev/dsk/c2t1d0s2

The HP-UX partition (block access)

/dev/rdsk/c2t1d0s2

The HP-UX partition (character access)

/dev/dsk/c2t1d0s3

The Service partition (block access)

/dev/rdsk/c2t1d0s3

The Service partition (character access)

Starting with the HP-UX 11i v3 release, you must have the persistent device special files. To

achieve this, use the insf command with the –e option or -eC disk option. If you are running

insf –e –H <hw_path>, you must run the insf command for both the legacy and new style

lun hardware path. For example:

# insf -e -H 0/5/1/0.5.14.0.0.0.1
