HP-UX Virtual Partitions Administrator Guide (includes A.05.07) (5900-1229, September 2010)

The following features can be executed only from the vPars-A.05.01/11.31-OS virtual partitions:
• creation, removal, and modification of a target virtual partition.
The vparcreate and vparremove operations can only be performed from the vPars
A.05.01/11.31-OS virtual partitions; vparmodify operations affecting other virtual partitions
can only be performed from the vPars A.05.01/11.31-OS virtual partitions.
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.

The following table highlights the above rules for having a mixed HP-UX 11i v2/v3 vPars
environment.
