For best performance, the VMS821I_IPMI-V0100 OpenVMS patch kit should be applied to OpenVMS running on
cell-based servers, such as HP Superdome servers, that are configured with more than one nPartition, regardless of
whether in a hybrid configuration. This patch kit is available from the HP website at http://www.itrc.hp.com/service/

Any of the supported operating systems listed in Table 1-2 can be used on a Superdome hybrid
server. If you are running the HP-UX 11i v1 December 2003 Release or HP-UX 11i v1 June 2004
Release, you must upgrade to the HP-UX 11i v1 December 2004 Release (or later HP-UX 11i v1
releases) for mixing support.
NOTE: In Superdome hybrid servers, there are some limitations and restrictions with Instant
Capacity (iCAP), Workload Manager (WLM), Global Workload Manager (gWLM), and Partition
Manager on HP-UX 11i v1.
Firmware and application updates can resolve these limitations.
WLM and gWLM Limitation in All Mixing Scenarios
Workload Manager (WLM) version A.03.00 and lower uses the uname -i command to ensure
that all the nPartitions it is managing are on the same Superdome server. WLM verifies that all
the managed nPartitions have uname -i values that match. The Intel Itanium 2 nPartitions and
PA-RISC nPartitions on the same Superdome hybrid server do not return the same uname -i
values. This prevents WLM from properly managing all the nPartitions on a Superdome hybrid
server with iCAP. This issue is fixed in WLM A.03.00.01 (released with HP-UX 11i v1 September
2005 Release). To use WLM in a Superdome hybrid server with iCAP, you must install/upgrade
to WLM A.03.00.01. On a Superdome hybrid server with no iCAP components, using WLM
A.02.x or WLM A.03.x does not require an upgrade.
Global Workload Manager (gWLM) v1.1.1 was first released with the HP-UX 11i v2 May 2005
Release. It has the same issue with the uname -i command as WLM. This only affects gWLM
iCAP shared resource domains (SRDs). Other gWLM shared resource domains (vPAR SRDs,
