Mixed HP-UX 11i v1/v2 vPars Environments in vPars A.04.05

Beginning with vPars A.04.05, you can have a mixed HP-UX 11i v1/v2 vPars environment on PA-RISC systems only. A mixed HP-UX 11i v1/v2 vPars environment enables you to have a vPars A.04.05 Monitor and database that supports both virtual partitions running vPars A.04.05 on HP-UX 11i v2 (11.23) and virtual partitions running vPars A.03.05 on HP-UX 11i v1 (11.11).

An example mixed HP-UX 11i v1/v2 vPars environment looks like the following:

Table 3-1 Mixed HP-UX 11i v1/v2 vPars Environment

HP-UX 11i v2 (11.23) running vPars A.04.05	HP-UX 11i v1 (11.11) running vPars A.03.05	HP-UX 11i v1 (11.11) running vPars A.03.05	HP-UX 11i v2 (11.23) running vPars A.04.05	HP-UX 11i v1 (11.11) running vPars A.03.05
vPars A.04.05 Monitor

Mixed HP-UX 11i v1/v2 vPars does not refer to mixing hardware (PA and Integrity) platforms. Additionally, virtual partitions running vPars A.05.xx on HP-UX 11i v3 (11.31), vPars A.04.04 and earlier on HP-UX 11i v2 (11.23), or vPars A.03.04 and earlier on HP-UX 11i v1 (11.11) are not supported in a mixed HP-UX 11i v1/v2 vPars environment.

Features of Mixed HP-UX 11i v1/v2 vPars Environments

The following are notable features of mixed HP-UX 11i v1/v2 vPars environments:

The vPars A.04.05 Monitor or later is required for a mixed HP-UX 11i v1/v2 vPars environment.
The vPars A.04.05 Monitor supports both virtual partitions running vPars A.04.05 on HP-UX 11i v2 (11.23) and virtual partitions running vPars A.03.05 on HP-UX 11i v1 (11.11).
The vPars A.03.05 Monitor supports booting only the HP-UX 11i v1 vPars A.03.05 environment.
The vPars A.03.05 Monitor does not support booting HP-UX 11i v2 environments and does not support Ignite-UX installation of HP-UX 11i v2 vPars using the vparboot -I command.
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.
