HP PRM Version C.03.05 Release Notes for HP-UX 11i v1, HP-UX 11i v2, and HP-UX 11i v3

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 prmconfig(1).)
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” (page 21).
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” (page 12).
Compatibility with online cell operations
If you want to perform online cell operations, and:
• Your PRM configuration contains memory records
Stop memory management (prmconfig -d MEM), then after the online cell operation has
completed, restart memory management (prmconfig -e MEM).
• Your PRM configuration uses PSETs
Reset PRM (prmconfig -r), then after the online cell operation has completed, restart
PRM management (prmconfig -ie [-f file]).
For more information on online cell operations, see parolrad(1M).
Compatibility with VERITAS File System (VxFS)
PRM can manage disk bandwidth for disks that are mounted and under the control of VERITAS
Volume Manager. However, PRM’s management does not work with VERITAS File System 4.0
and later.
Compatibility with Trusted Systems
PRM is supported on Trusted Systems.
