HP 3PAR Upgrade Pre-Planning Guide

9 HP-UX Guidelines
IMPORTANT: To preserve the boot from SAN (BFS) setup for HP-UX PA-RISC servers running any
supported OS version, the following steps must be completed before rebooting the server and after
the HP 3PAR OS on the arrays is upgraded.
After the HP 3PAR OS on the array is upgraded, run the following commands before rebooting
the server:
1. Run the insf -e command.
2. Run the ioscan command.
3. Use the setboot command to reset the primary and alternate boot paths as well as HA if it
is available.
For example, on 11i v3 (11.31):
Using the lvlnboot -v command and the setboot -v | head -5 command on the HP-UX
server.
#lvlnboot -v
Boot Definitions for Volume Group / dev/vg00:
Physical Volumes belonging in Root Volume Group: /dev/disk/disk8 -- Boot Disk
Boot: lvol1 on: /dev/disk/disk8
Root: 1vol3 on: /dev/disk/disk8
Swap: lvol2 on: /dev/disk/disk8
Dump: lvol2 on: /dev/disk/disk8, 0
#setboot -v
Primary bootpath: 1/0/14/1/0.0x21120002ac0010e6.0x4001000000000000(/dev/rdisk/disk8) <= BFS Boot LUN
HA Alternate bootpath: 1/0/4/1/0/4/0.0x21110002ac0010e6.0x4001000000000000
Alternate bootpath: 1/0/0/2/0.0x6.0x0 (/dev/rdisk/disk5) <= Internal Boot LUN
In this particular example, the setboot command would be:
setboot -p /dev/rdisk/disk8 -a /dev/rdisk/disk5 -h /dev/rdisk/disk8
For example, on 11i v2 (11.23):
Using the lvlnboot -v command and the setboot -v | head -5 command on the HP-UX
server.
#lvlnboot -v
Current path "/dev/dsk/c10t0d2" is an alternate link, skip.
Boot Definitions for Volume Group /dev/vg00:
Physical Volumes belonging in Root Volume Group: /dev/dsk/c8t0d2 (0/5/1/0/4/0.8.0.0.0.0.2) -- Boot Disk /dev/dsk/c10t0d2
(0/5/2/0.8.0.0.0.0.2)
Boot: lvol1 on: /dev/dsk/c8t0d2/dev/dsk/c10t0d2
Root: lvol3 on: /dev/dsk/c8t0d2/dev/dsk/c10t0d2
Swap: lvol2 on: /dev/dsk/c8t0d2/dev/dsk/c10t0d2
Dump: lvol2 on: /dev/dsk/c8t0d2, 0
#setboot -v
Primary bootpath: 0/5/1/0/4/0.8.0.0.0.0.2 <= BFS Boot LUN
Alternate bootpath: 0/1/1/0.1.0 <= Internal Boot LUN
In this particular example, the setboot command would be:
setboot -p 0/5/1/0/4/0.8.0.0.0.0.2 -a 0/1/1/0.1.0
NOTE: The following HP 3PAR OS online upgrades have been determined to cause HP-UX servers
to report device discovery problems until the upgrade is complete:
• HP 3PAR OS 3.1.1 (including all MUs) to 3.1.2 MU1, 3.1.2 MU2, or 3.1.2 MU3
• HP 3PAR OS 3.1.2 GA to 3.1.2 MU1, 3.1.2 MU2, or 3.1.2 MU3
