HP PRM Version C.03.02.xx Release Notes for HP-UX 11i v1, HP-UX 11i v2, and HP-UX 11i v3

PRM Release Notes
Compatibility information and installation requirements
Chapter 116
Compatibility with HP Integrity Virtual Machines
HP Integrity Virtual Machines (Integrity VM) is a robust soft partitioning and virtualization
technology that provides operating systems isolation, shared CPU (with sub-CPU
granularity), shared I/O, and automatic, dynamic resource allocation. It is available for
HP-UX 11i v2 running on HP Integrity servers.
Given a system with Integrity VM installed, you can run PRM inside any of the virtual
machines; however, you cannot run PRM on the VM host as the vm_fssagt already controls
FSS groups on behalf of Integrity VM.
NOTE Do not specify disk bandwidth records for configurations used inside virtual
machines.
Compatibility with processor sets (PSETs)
PRM allows you to define PRM groups based on PSETs.
NOTE When you have PRM groups based on PSETs enabled:
• Do not modify the PSETs manually using the psrset command
• Do not adjust CPU counts in virtual partitions using the vparmodify
command
• Do not adjust Instant Capacity (iCAP), Temporary Instant Capacity
(TiCAP), or Pay Per Use resources using the icapmodify or ppuconfig
commands
• Do not perform online cell operations, using parolrad or any other
interface, while PRM is managing the system (For more information, see
the WARNINGS section in the prmconfig(1) manpage.)
Compatibility with WLM
You can use PRM with HP-UX Workload Manager (WLM) under certain conditions—as
explained in the WLM Release Notes.
When upgrading WLM, be careful of the order of upgrades, as explained in “Upgrading or
installing PRM before upgrading WLM from C.03.00 or earlier can cause WLM to fail swverify
checks” on page 26.
