HP-UX Virtual Partitions Release Notes (A.05.01)

vPars Release Notes

What’s New in this Version of vPars (A.05.01)

Chapter 16

For a primer on setting hyperthreading, see the A.05.01 Resources chapter in the HP-UX

Virtual Partitions Administrator’s Guide. For complete information on hyperthreading,

see the nPartitions Administrator’s Guide.

NOTE In order to work in a vPars environment, hyperthreading requires the

ﬁrmware revisions indicated in the HP-UX Virtual Partitions Ordering and

Conﬁguration Guide.

• Pending CPU and Memory Migration Operations

After dynamically adding CPUs or Memory to a virtual partition, you can cancel the

operation if it is pending by using vparmodify -C

sequenceID

, where sequenceID is the

corresponding sequenceID number shown in the vparstatus output.

For more information, see the A.05.01 Resources chapter in the HP-UX Virtual Partitions

Administrator’s Guide.

• Mixed HP-UX 11i v2/v3 vPars Environments

Beginning with vPars A.05.01, you can use a mixed HP-UX 11i v2/v3 vPars environment.

A mixed HP-UX 11i v2/v3 vPars environment allows you to 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 later on HP-UX 11i

v2 (11.23). Virtual partitions running vPars A.03.xx on HP-UX 11iv1 (11.11) are not

supported in a mixed HP-UX 11i v2/v3 vPars environment. Please note that mixed does

not refer to mixing PA and Integrity platforms.

For detailed information, see the Mixed HP-UX 11i v2/v3 vPars section in the Planning

chapter of the HP-UX Virtual Partitions Administrator’s Guide.

• Updating from vPars A.04.xx to A.05.01

Updating directly from vPars A.04.xx to A.05.01 is supported.

Updating directly from vPars A.03.xx to A.05.01 is not supported, because updating

directly from an 11.11 OE to an 11.31 OE is not supported,

For instructions on updating, see the Installation chapter in the HP-UX Virtual Partitions

Administrator’s Guide.

• PCI OL* 11.31 Features

The PCI OL* error recovery features that are supported in 11.31 are also supported

within a vPars environment. For complete information on PCI OL* error recovery, see the
