Partitions Administrator’s 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 24). These servers remain
supported for A.03.xx and A.04.xx.
2.3.2 vPars A.04.xx Releases
vPars A.04.06 vPars A.04.06 adds support for the following: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.
IMPORTANT: In certain situations while using vPars with SAS disks as boot disk on HP
Integrity platforms, the vparstatus -v and setboot commands may show different
boot disk paths in vPars mode. This behavior is normal, and is due to the disks being scanned
in a different sequence at boot time. This behavior also occurs when you boot into nPars
mode and then boot back in vPars mode.
For example:
1. A virtual partition is ignited from a SAS disk and booted in vPars mode, and the
vparstatus -v command displays the boot disk path as A.
2. If the system is booted back to nPars mode, the boot path may change to B, which is
different from A due to a different scan order. This would also change the boot path to
B in the vPars database (/stand/vpdb).
3. After booting back to vPars mode, the vparstatus -v command for this virtual
partition shows B as the boot path and the setboot command still shows A. Both boot
paths (A and B) refer to the same SAS disk path.
vPars A.04.05 vPars A.04.05 adds support for the following:
• Support for mixed HP-UX 11i v1/v2 vPars environments.
Beginning with vPars A.04.05, you can can have a mixed HP-UX 11i v1/v2 vPars environment.
A mixed HP-UX 11i v1/v2 vPars environment enables you to have a vPars A.04.05 Monitor
and database that supports both virtual partitions running vPars A.04.05 on HP-UX 11i v2
(11.23) and virtual partitions running vPars A.03.05 on HP-UX 11i v1 (11.11). For detailed
information, see the “Mixed HP-UX 11i v1/v2 vPars Environments in vPars A.04.05” section
in the “Planning” chapter of the HP-UX Virtual Partitions Administrator’s Guide.
• Support for boot and recovery from DVD (HP Integrity servers only).
vPars A.04.05 supports booting from CD/DVD media on HP Integrity servers.
vPars A.04.04 vPars A.04.04 adds support for the following:
