How to mirror a HP-UX 11i VxVM 4.1 or 5.0.1 boot disk
From Wiki-UX.info
Abstract
This article demostrates the usage of the vxboot_mirr command to create a Veritas Volume Manager boot mirror, using either VxVM version 4.1 or 5.0.1.
This article is useful to aid engineers handling the task for the first time to complemented the examples provided by the corresponding Administration Guides.

Use vxboot_mirr script to build the VxVM boot mirror
The VxVM boot mirror creation is automate using the vxboot_mirr script. The command accepts both legacy and agile addressing device special files.
# /etc/vx/bin/vxrootmir -v [legacy | agile]
For example:
# /etc/vx/bin/vxrootmir -v c0t1d0

NOTE: For each volume there are two plexes and two subdisks, backed by the two disks holding the boot volume.
Use setboot command to set the alternate and high availability boot disks
The setboot command is used to define the alternate boot disk. On Integrity system, there are two alternate boot disk pointers available, High Availability and Alternate. The High Availability is tried next after the primary boot path fails.
HP-UX 11i v2:
# setboot
Primary bootpath : 0/0/2/0.0.0
HA Alternate bootpath : <none>
Alternate bootpath : <none>
Autoboot is ON (enabled)
# setboot -a 0/0/2/0.1.0
# setboot -h 0/0/2/0.1.0
# setboot
Primary bootpath : 0/0/2/0.0.0
HA Alternate bootpath : 0/0/2/0.1.0
Alternate bootpath : 0/0/2/0.1.0
HP-UX 11i v3:
# setboot
Primary bootpath : 0/0/2/0.0x0.0x0 (/dev/rdisk/disk0)
HA Alternate bootpath :
Alternate bootpath :
Autoboot is ON (enabled)
# setboot -a 0/0/2/0.0x1.0x0
# setboot -h 0/0/2/0.0x1.0x0
# setboot
Primary bootpath : 0/0/2/0.0x0.0x0 (/dev/rdisk/disk0)
HA Alternate bootpath : 0/0/2/0.0x1.0x0 (/dev/rdisk/disk1)
Alternate bootpath : 0/0/2/0.0x1.0x0 (/dev/rdisk/disk1)
