vPars A.05.05 Release Notes This document provides information about the HP-UX Virtual Partitions (vPars) A.05.05 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.
vPars Checklist This section is a brief checklist of common but significant items you should check while setting up vPars. Firmware Checklist • Check Server Firmware: Check the HP-UX Virtual Partitions Ordering and Configuration Guide for the required server firmware. For the non-nPartition-able systems, firmware upgrades must be done outside of the vPars environment (in standalone mode). For nPartition-able systems, call your HP Support Representative.
OS-Prompt> reboot /* to reboot the system into vPars mode */ • If you are at the Monitor prompt, use the following Monitor command to switch to nPars mode: MON> reboot nPars /* sets the mode and reboots the system */ • If you are at the EFI shell prompt, use the following EFI utility to switch to either nPars or vPars mode: Shell:> fsN: fsN:> vparconfig reboot nPars|vPars Since vparconfig is not a built-in EFI shell command, you must go to the disk to execute vparconfig.
Known Problems and Workarounds This section provides a list of problems and limitations known to HP at the time of publication. If workarounds are available, they are included.

• On PA-RISC Servers, Booting a Fibre Channel Tape Device May Cause the Target Virtual Partition to Hang Related Defect ID and Patch Number JAGaf09885 Applicable On — vPars A.05.xx on PA-RISC — vPars A.04.03 on PA-RISC Description If you attempt to boot a virtual partition using a Fibre Channel tape device that has been configured using the :TAPE attribute, the target virtual partition may hang.
winona1# vparreset -p winona2 -h 2. When the target partition is in the down state, attempt booting the partition using vparboot.

Description Initiating a Transfer of Control (TC) at the Guardian Service Processor GSP, while the vPars Monitor is booted, may cause the hard partition or system to hang. Symptoms If the vPars Monitor is booted and a TC is issued via the GSP, the hard partition or system may hang. Workaround • If the hard partition or system hangs, issue an RS (hard reset) at the GSP.
