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 using the idisk command and a partition description file.

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, run the following command:

# idisk /dev/rdsk/c2t1d0

2. Use the insf command with the -e option to create the device files for all the partitions. For example:

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

You should 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)

3. Create a physical volume using pvcreate with the -B option. Be sure to use the device file denoting the HP-

UX partition.

# pvcreate -B /dev/rdsk/c2t1d0s2

4. Add the physical volume to your existing root volume group using vgextend:

# vgextend /dev/vg00 /dev/dsk/c2t1d0s2

5. Use the mkboot command to set up the boot area. Specify the -e and -l options to copy EFI utilities to the

EFI partition, and use the device special file for the entire disk:

1 2 ... 21 22 23 24 25 26 27 28 29 30 31 ... 35 36
