PRM Release Notes
Compatibility information and installation requirements
Chapter 1 15
Compatibility with processor sets (PSETs)
PRM allows you to define PRM groups based on PSETs.
NOTE When you have PRM groups based on PSETs, disable PRM to perform any of
the following operations:
• Modify the PSETs manually using the psrset command
• Adjust core (CPU) counts in virtual partitions using the vparmodify
command
• Adjust Instant Capacity (iCAP), Temporary Instant Capacity (TiCAP), or
Pay Per Use resources using the icapmodify or ppuconfig commands
• 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 have distinct PRM and WLM configurations in use at the same time. For example, the
WLM configuration could be managing only the migration of CPU resources across virtual
partitions or nPartitions. For more information, see 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 24.
Compatibility with gWLM
PRM and HP Global Workload Manager (gWLM) should not be used to manage the same
system at the same time. Using these products to control resources at the same time may
cause inconsistent behavior and undesirable performance.
Compatibility with long hostnames
PRM supports long hostnames. You must install the bundle NodeHostNameXpnd and
configure the feature first though. For more information, see the section “Installation
procedure for B3835DA” on page 8.
