HP Integrity Virtual Machines Version 4.2 Release Notes

6.16.3 File Permission Errors When Checking or Applying Integrity VM Serviceguard
Packages to the Cluster Configuration
Depending on the system configuration, you might see an error similar to the following when
running cmcheckconf or cmapplyconf to the virtual machine packages:
# cmapplyconf -P /etc/cmcluster/hpvm-sg1-g4/hpvm-sg1-g4.conf
Incorrect permissions for /etc/cmcluster/hpvm-sg1-g4 (40777). Directory must be executable for owner, and not
writable by group and others on node hpvm-sg1-h1.
cmapplyconf: Error found in package file: /etc/cmcluster/hpvm-sg1-g4/hpvm-sg1-g4.conf.
To correct this issue, use a chmod command similar to the following to correct the permission
of the package directory on each of the cluster members:
# chmod go-w /etc/cmcluster/hpvm-name
6.16.4 Status of Serviceguard Controlled Distributed Guests can Lag
When Integrity VM guests are configured as packages in a Serviceguard (SG) cluster, hpvmstatus
displays which VM Host is running the distributed guests as an SG package. Because this
information comes from SG, it can be delayed by as much as 10 seconds. This delay does not
cause any risk of starting the same guest on two different Integrity VM Hosts, because SG is
controlling the start of these guests and allows only a single instance to run at any one time.
6.16.5 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/
6.16.6 Problem Displaying Truncated IPv6 Address for AVIO LAN with hpvmstatus
and hpvmnet Commands
For a guest configured with the AVIO adapter as a network device (avio_lan) and also configured
with an IPv6 address, the IPv6 address displayed by hpvmstatus -V and hpvmnet -V may
be truncated.
6.16.7 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.
6.16.8 Required HP Serviceguard Patches
To use Serviceguard to manage HP-UX guests, make sure the required patches are installed. For
more information, see Section 2.4 (page 28).
6.16.9 Reenter Command to Start Packages
The procedure for configuring and starting guest packages includes the cmrunpkg command.
This command does not always work the first time you enter it. If the command does not start
the package, re-enter the command.
6.16.10 Do not Use Integrity VM Commands to Manage Distributed Guests
Guests configured as Serviceguard packages should only be stopped and started using
Serviceguard package control commands. Do not use the Integrity VM commands (hpvmstart,
