HP Integrity Virtual Machines Release Notes Version A.03.50

6.7 HP-UX 11i v3 Guests Might Panic with a NaT_hndler: kernel NaT
Consumption Fault
Under certain situations, an HP-UX 11i v3 guest might panic with a NaT_hndler: kernel
NaT Consumption fault when using Logical Volume Manager (LVM) software.
To avoid this situation, install the BaseLVM (B.11.31.0712) software from the HP-UX 11i v3 0712
AR media.
6.8 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.
6.9 The hpvmconsole pc –cycle Command Occasionally Doesn’t
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
6.10 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.
6.11 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.
6.11.1 The hpvmsg_package Does Not Add Appropriate Entries
The hpvmsg_package does not add appropriate entries to the package configuration and control
script files. After running the /opt/cmcluster/toolkit/hpvmsg_package script to package
a guest that contains CVM or CFS backing stores, review and modify the package configuration
and control scripts for each cluster member. As part of this process, add CVM and/or CFS backing
store entries to these files.
The package configuration and control scripts can be found at: /etc/cluster/guest-name/
6.11.2 Using AVIO lan Device in a Serviceguard Configured Guest
When using AVIO networking devices for guests that are configured as Serviceguard Packages,
be sure that all Serviceguard standby lans are configured using PPA devices supported by
AVIO. Failure to do so causes network connectivity to be lost even if the standby link is up.
