HP-UX Virtual Partitions Administrator Guide - Hewlett Packard

Using Primary and Alternate Paths with nPartitions
The vPars database and the nPartition complex profile are entirely separate. Therefore, a change
in the vPars database does not change any complex profile data.
A change in the primary or alternate paths in the vPars database does not change the primary
or alternate paths in the complex profile. To change the primary or alternate paths for both a
virtual partition and its nPartition, you must change the paths for each separately.
NOTE: For an EFI system, the above is true even if you use parmodify to change the paths.
parstatus will show them as set; however, once the system is booted into nPars mode, those
changes by parmodify are not retained.
Example
Original Status:
Suppose a vparstatus output of keira1 showed the alternate boot path to be 0/0/6/0/0.6.0
(irrelevant output omitted):
keira2# vparstatus -p keira1 -v
[Virtual Partition Details]
Name: keira1
State: Down
Attributes: Dynamic,Autoboot
.
.
.
[IO Details]
0.0.6
0.0.6.0.0.5
0.0.0
0.0.4
0.0.2
0.0.6.0.0.5.0 BOOT
0.0.6.0.0.6.0 ALTBOOT
and its nPartition showed the nPartition’s alternate path to be 2/0/14/0/0.6.0:
keira2# parstatus -p0 -V
[Partition]
Partition Number : 0
Partition Name : npar0
Status : active
IP address : 0.0.0.0
PrimaryBoot Path : 0/0/6/0/0.5.0
Alternate Boot Path : 2/0/14/0/0.6.0
HA Alternate Boot Path : 0/0/6/0/0.5.0
.

Changing the Virtual Partition’s Path (vPars Partition Database)
To change keira1’s alternate boot path to the boot disk at 0/0/6/0/0.4.0, run the command:
keira2# vparmodify -p keira1 -a io:0.0.6.0.0.4.0:ALTBOOT
vparstatus now shows:
keira2# vparstatus -p keira1 -v
[Virtual Partition Details]
Name: keira1
State: Down
Attributes: Dynamic,Autoboot
Kernel Path: /stand/vmunix
