HP-UX Virtual Partitions

HP-UX Virtual Partitions (vPars) A.04.01 enables multiple instances of a selected

HP-UX 11i v2 OE to run simultaneously on one server or within one nPartition, with

each OE instance hosting its own set of applications in an isolated environment.

When vPars A.04.01 is available, you can purchase it at the HP-UX Virtual Partitions at

the HP Software Depot at http://software.hp.com.

Prior to or while installing vPars A.04.01, you must cold-install or update to the HP-UX

11i v2 May 2005 Operating Environments (OE) Update Release, which is delivered by

the OE media. The OE media delivers updated components for the full support of vPars,

including the FEATURE11i patch bundle, which contains the core patches required for

vPars installation and support. (See “Feature Enablement Patch Bundle (Feature11i)” on

page 98.)

The vPars product for HP-UX 11i v2 May 2005 will require an update of System and/or

Manageability Firmware. See the HP-UX Virtual Partitions Ordering and Configuration

Guide at http://docs.hp.com/hpux/os/11i/index.html#Virtual%20Partitions.
