HP-UX Virtual Partitions Administrator's Guide (includes A.05.02)

Planning Your System for Virtual Partitions

Mixed HP-UX 11i v2/v3 vPars Environments in vPars A.05.xx

Chapter 3

Note that this only applies to performing these operations on other virtual partitions. Operations where

the source and target virtual partition are the same are always supported, regardless of whether you are

in a mixed HP-UX 11i v2/v3 vPars environment or not.

When the ﬂexible administrative capability is ON, setting the vPars A.04.xx/11.23-OS virtual partitions

as the only designated-admin virtual partitions is not recommended. If all the designated-admin virtual

partitions are vPars A.04.xx/11.23-OS virtual partitions, no partitions will be able to perform

vparmodify, vparremove, or vparcreate operations on other partitions.

The following features work

only between

the vPars-A.05.01/11.31-OS virtual partitions:

• dynamic memory migration

In a mixed HP-UX 11i v2/v3 vPars environment, dynamic memory migration is only supported on the

vPars versions that support dynamic memory migration. In other words, the source and target virtual

partitions must be running vPars A.05.xx.

It is possible to perform add/delete memory operations on virtual partitions running A.04.xx, as long as

the target virtual partition is in the down state. Note that the vparmodify command must be executed on

a virtual partition running vPars A.05.xx.

The following features are

not allowed

in a mixed HP-UX 11i v2/v3 vPars environment:

• HT ON

Because hyperthreading is an 11.31 feature, when hyperthreading is enabled (HT is ON), only the vPar

A.05.01/11.31 virtual partitions will boot; the vPars A.04.xx/11.23 virtual partitions will not boot.

Version Requirements:

• Only the vPars A.05.01 Monitor supports a mixed HP-UX 11i v2/v3 vPars environment; therefore, for

both 11.31 and 11.23 OS instances to be running, the vPars A.05.01 Monitor must be booted.

Note that this implies there must always be at least one vPars A.05.01 virtual partition in a given mixed

HP-UX 11i v2/v3 vPars conﬁguration. The vPars A.05.01 virtual partition need not be up and running.

However, when running only vPars A.04.xx virtual partitions on a vPars A.05.01 Monitor, keep in mind

the administrative restrictions on the vPars A.04.xx virtual partitions described in this section.

If a vPars A.04.02 Monitor is booted, the vPars A.05.01 virtual partitions will not boot.

• The 11.23 OS instances must be running vPars A.04.02 or later; vPars A.04.01 is not supported. The

11.31 OS instances must be running A.05.01 or later. HP-UX 11.11 OS/vPars A.03.xx instances are not

supported.

• The ﬁrmware requirements for the system will follow that of vPars A.05.01.
