HP-UX Virtual Partitions Release Notes (A.05.01)

Read Before Installing
Mixed HP-UX 11i v2/v3 vPars Environments in vPars A.05.xx
Chapter 216
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. 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.
