HP-UX Virtual Partitions Administrator Guide (includes A.05.09) (5900-2188, March 2012)

• HP-UX 11i v1 virtual partitions (running vPars A.03.05) can use vparmodify on itself only,
and cannot use the vparcreate and vparremove commands. Thus, in a mixed HP-UX 11i
v1/v2 vPars environment, an HP-UX 11i v1 virtual partition cannot remove virtual partitions,
cannot create new virtual partitions, and can modify only itself.
• HP-UX 11i v2 virtual partitions (running vPars A.04.05) have no vPars command restrictions
as compared with a pure HP-UX 11i v2 vPars environment.
• The status details reported by vparstatus are determined by the target virtual partition
version and the vPars software version of the virtual partition issuing the command:
◦ When vparstatus is run from an HP-UX 11i v2 virtual partition targeting an HP-UX 11i
v1 virtual partition, the result is shown in HP-UX 11i v2 (vPars A.04.05) format.
◦ The vparstatus command run from an HP-UX 11i v1 virtual partition does not report
cell local memory (CLM) and cell local processor (CLP) details for HP-UX 11i v2 virtual
partitions, even if they have CLM or CLP configured.
Likewise, the vparstatus -A command run from an HP-UX 11i v1 virtual partition does
not display CLP information.
◦ HP-UX 11i v1 bound processors are shown only when the HP-UX 11i v1 virtual partition
is in an “up” state.
◦ The vparstatus command run from an HP-UX 11i v1 virtual partition reports an HP-UX
11i v1 virtual partition's bound and float CPUs in legacy format.
The vparstatus command run from an HP-UX 11i v1 virtual partition reports that an
HP-UX 11i v2 virtual partition's monarch CPU is “bound” and all other CPUs are shown
as unbound (floater).
• The vparstatus -P command option is provided to display the HP-UX version running on
virtual partitions in a mixed HP-UX 11i v1/v2 vPars environment.
• When the vPars Flexible Administrative Capability feature is enabled, a vPars A.04.05 virtual
partition should be the designated-admin virtual partition. Because of HP-UX 11i v1 virtual
partition command restrictions in mixed HP-UX 11i v1/v2 vPars environments, if only vPars
A.03.05 virtual partitions are configured to be designated-admin, then no virtual partitions
will be able to perform vparmodify, vparremove, or vparcreate operations on other
virtual partitions.
• HP Global Workload Manager (gWLM) is supported in mixed HP-UX 11i v1/v2 vPars
environments with the following restrictions:
◦ Do not nest processor sets (Psets) under vPars A.03.05.
◦ Do not assign CLPs to any of the virtual partitions.
For details about these restrictions for using gWLM in a mixed HP-UX 11i v1/v2 vPars
environment see the HP-UX Virtual Partitions Release Notes (A.03.05).
• The Virtual Partition Manager (vparmgr) GUI is supported only on HP-UX 11i v1 virtual
partitions in mixed HP-UX 11i v1/v2 vPars environments.
