HP Integrity Virtual Machines Version 4.2 Release Notes

6.13 How to Stop Guests
To stop a guest, HP recommends that you perform an operating system shutdown from a
privileged account on the guest. If the guest is not responding, use the hpvmstop -g command
on the VM Host. Do not stop a guest by killing the hpvmapp process.
6.14 The hpvmconsole pc –cycle Command Occasionally Does not
Complete
If the guest hpvmconsole pc –cycle command doesn’t complete and restart the guest, enter
Ctrl/B to interrupt the command and then press Enter to return to the virtual console. Exit the
virtual console by entering the X command. At the VM Host command prompt, enter the following
command to start the guest:
# hpvmstart –P guestname
6.15 How to Recover from a Guest Hang
If a guest hangs, attach to the guest's virtual console using the hpvmconsole command, then
use Ctrl/B to enter the virtual console. Enter the tc command to reset the guest. The guest
captures a memory dump of the machine state, which can be used later for offline diagnosis. Do
not kill the guest from the VM Host or use the virtual console to power down a hung guest.
Doing so can corrupt the guest file system.
6.16 Using HP Serviceguard to Manage Guests
This section lists release notes specific to using Serviceguard in the Integrity VM environment.
Do not attempt to use guests as Serviceguard packages and guests as Serviceguard nodes at the
same time on the same VM Host system.
You can install HP Serviceguard A.11.16 or 11.17 on the VM Host or on the HP-UX guest. You
can install HP Serviceguard 11.18 only on guests running HP-UX 11i v3.
6.16.1 Serviceguard 11.18 No Longer Supported
Starting with HP Integrity Virtual Machines, Version 4.2, Serviceguard 11.18 is no longer
supported with Integrity VM.
6.16.2 Packaging VM Guest with CFS/CVM Backing Stores as Serviceguard
Packages
When creating a Serviceguard cluster with virtual machines acting as packages, the
hpvmsg_package script correctly identifies CVM logical volumes and CFS files backing stores
used by guests but requires users to verify or provide activation modes and package dependencies
for the backing stores.
The hpvmsg_package script creates the package configuration in the package directory:
/etc/cmcluster/hpvm-name/hpvm-name.conf. Inside the configuration file are instructions,
examples, and default and assigned named-values pairs describing the resources used by the
virtual machines and controlled and monitored by Serviceguard.
For information about selecting the appropriate values for these items, see the templates files in
the Managing Servicguard manual and the Veritas Storage Foundation 5.0 Cluster File System
Administration Guide Extracts for HP Serviceguard Storage Management Suite.
