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

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 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:
• Support for PA-RISC Servers Using the HP sx2000 Chipset
Support for the following PA-RISC servers using the HP sx2000 chipset: rp7440, rp8440, and
HP 9000 Superdome.
• Pre-enablement of SCSI Tape Boot and Recovery for Integrity Servers
On Integrity servers running vPars A.04.04, you are pre-enabled to use tape devices from
within the vPars environment—this includes recovery using tape devices. Note that you are
pre-enabled to use only the tape devices that are already supported with Integrity servers in
stand alone mode. vPars does not support devices beyond those that are supported by the
server itself.
vPars A.04.03
vPars A.04.03 adds support for the following:
• Tape Devices on PA-RISC Servers
On PA-RISC servers, you can use tape as boot devices from within the vPars environment; this
includes recovery using tape devices. For more information, see the recovery chapter in the
HP-UX Virtual Partitions Administrator Guide
