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:
3
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:
The entire disk (block access)
The entire disk (character access)
The EFI partition (block access)
The EFI partition (character access)
The HP-UX partition (block access)
The HP-UX partition (character access)
The Service partition (block access)
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
