HP-UX Virtual Partitions Ordering and Configuration Guide (March 2012)

vPars A.05.01
vPars A.05.01 adds support for the following:
• 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 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 Guide.
• Hyperthreading
Hyperthreading can be enabled in a vPars environment if the processor hardware supports
it. Each vPar OS and applications will be able to take advantage of CPU-threading, just as
in an nPartitions environment. Processor assignments and migration will continue to be
supported at the CPU-core level though. For more information, see the “A.05.01 Resources”
chapter in the HP-UX Virtual Partitions Administrator Guide.
• Mixed HP-UX 11i v2/v3 vPars Environments
You can now have a vPars A.05.01 monitor and database that simultaneously supports virtual
partitions running vPars A.05.01 on HP-UX 11i v3 (11.31) and virtual partitions running vPars
A.04.02 or above on HP-UX 11i v2 (11.23). For detailed information, see the “Mixed HP-UX
11i v2/v3 vPars” section in the “Planning” chapter of the HP-UX Virtual Partitions Administrator
Guide.
• Obsolescence Notes
vPars A.03.02 is no longer supported. See “Obsolescence of vPars Releases” (page 20).
Servers that are not nPartitionable are not supported under A.05.01. These servers are the
rp5470/L3000, rp5405, and rp7400/N4000. See “Servers” (page 25). These servers
remain supported for A.03.xx and A.04.xx.
2.3.2 vPars A.04.xx Releases
vPars A.04.07
There are no new or changed features in the vPars A.04.07 release.
vPars A.04.06
The following features are new with the vPars A.04.06 release:
• Enhanced dynamic vPars support with Oracle Real Application Clusters (RAC) on HP 9000
PA-RISC servers
NOTE: This functionality is already available on vPars A.04.04 for Integrity servers.
• PCIe SAS support and tape recovery feature on Integrity servers
vPars A.04.06 on HP Integrity platforms enables you to use SAS disks as boot devices in vPars
environment.
