HP-UX Virtual Partitions Administrator Guide (includes A.05.08) (5900-1312, March 2011)

• HP-UX 11i v1 virtual partitions (vPars A.03.05) does not support CLM or CLP resources.
It is possible—but not supported—to add CLM or CLP resources to an HP-UX 11i v1 virtual
partition when it is in a “down” state. However, booting an HP-UX 11i v1 virtual partition will
be halted if it has CLM or CLP resources assigned to it.
• The system firmware must match the vPars A.05.03 firmware requirements.

LORA Support
Starting with vPars A.05.05, LORA is enabled on multi-cell Integrity systems. LORA support provides
the vPars processor core selection algorithms to enable CPU allocation based on memory proximity
to the partition. This enables vPar systems to produce better data transfer rate and reduce time to
