HP-UX Virtual Partitions Release Notes (A.05.04)

vPars A.05.04 Release Notes
This document provides information about the HP-UX Virtual Partitions (vPars) A.05.04 release.
vPars Overview
The HP-UX Virtual Partitions (vPars) product runs multiple instances of HP-UX simultaneously
on one server, or nPartition, by dividing it into virtual partitions. Each virtual partition is assigned
its own subset of hardware, runs a separate instance of HP-UX, and hosts its own set of
applications. vPars provides application and operating system fault isolation.

New Features
The following features are new with the vPars A.05.04 release:
• Support for Directed LAN Boot feature on HP Integrity systems based on the sx1000 and

Directed Lan Boot (Direct Boot) capability allows a system administrator or a user to specify
boot server information in vparboot command, which is typically obtained through the
BootP or DHCP protocols. With this feature, you can install to a virtual partition from an
Ignite Server which can be in a different subnet. For more information, see the vparboot(1M)
and vpardbprofile(1M) manpages.

of 8 KB, 16 KB, and 64 KB are available. This enhancement is available in Update 3 (the
