HP vPars and Integrity Virtual Machines V6.1 Administrator Guide

4.1.6 Verifying vPars/VM after installing layered products
Follow these steps after installing layered products:
1. Start and stop each guest, one at a time, and make sure that they boot to their OS.
2. Use the guest troubleshooting section, Chapter 13 (page 215), to resolve guest booting problems.
3. Upgrade each guest with the new guest kit.
4. Make sure there are no network issues
5. If the guest OS is no longer supported, upgrade the guest OS.
NOTE: When Integrity VM is stopped either with the /sbin/init.d/hpvm stop command
or as a result of removing or updating the version of Integrity VM on the VSP, messages of the
following form might be logged in the /var/opt/hpvm/common/command.log file:
ERROR|host|root|Unable to communicate with the FSS agent
The messages, which are a result of interactions with the performance metrics processes scopeux
and perfd, are normally transient and stop after about a minute. Approximately 60-70 messages
might be generated in that time. You can clear this condition by either rebooting the VSP or by
stopping and restarting the metrics collection processes.
To stop and restart the perfd process, use the following commands:
# /sbin/init.d/pctl stop
# /sbin/init.d/pctl start
To stop and restart the scopeux process, use the following commands:
# /sbin/init.d/ovpa stop
# /sbin/init.d/ovpa start
4.1.7 Upgrade troubleshooting issues
After you upgrade to 11i v3, examine the following issues:
• Mass storage issues
The Integrity VM V6.1 release supports the use of both legacy and agile devices in guests. It
is not necessary to convert guests to use strictly agile devices. If, however, problems occur
with guests using multipath solutions that are based on legacy devices, change the backing
device to use the equivalent agile device. For information about mass storage compatibility
issues, see the documentation on the BSC website:
HP-UX 11i v3 Manuals.
• Platform issues
For 11i v3 platform support, see the following matrix:
HP-UX Integrity Server Support Matrix
• Serviceguard issues
For information about the Storage Multi-Pathing choices in HP-UX Serviceguard environments,
see the Serviceguard website:
HP Serviceguard Solutions
• Other issues
4.2 Updating previous versions of the VSP to Integrity VM V6.1
This section describes the process of updating a previous version of the VSP to Integrity VM V6.1.
Once you have read the product release notes and verified that you have met the system
requirements, install the Integrity VM software as described in this section.
