What is new in this version?
vPars A.05.xx Releases
vPars A.05.01:
 Dynamic Memory Migration: You can add memory to or delete memory from a
virtual partition while it is up (online). When memory is assigned to a virtual
partition, it can be categorized as “float” (i.e., can be added or deleted while the
virtual partition is up), or “base” (i.e., cannot be deleted while the virtual partition is
up). By default, all memory assigned to a virtual partition during the vPar creation or
memory addition, is considered base memory. For more information, see the A.05.01
resources chapter in the “HP-UX Virtual Partitions Administrator's Guide”.
 Hyperthreading can be enabled in a vPars environment, if the processor hardware
supports it. Each vPar operating system and applications will be able to take
advantage of CPU threading, just as in an nPar environment. Processor assignments
and migration will continue to be supported at the CPU core level though. For more
