2.2.2 Compatibility of VSE V4.1 with Integrity VM V4.2
You can use Version 4.1 of the VSE Suite with Integrity VM Version 4.2, but this version of the
VSE Suite does not support the new features in Integrity VM Version 4.2.
2.3 Known Issues and Information
The following sections describe known issues and information from previous releases that still
apply to V4.2.
2.3.1 Warning Messages That Can be Ignored
During the installation or update of Integrity VM along with the HostAvioLan and/or the
HostAVIOStor products, you might see the following warning messages in the /var/adm/
syslog/syslog.log file:
WARNING: mod_uninstall: Attempt to uninstall hvsd module: Module is not installed
WARNING: mod_uninstall: Attempt to uninstall hssn module: Module is not installed
These warning messages can be safely ignored.
2.3.2 Large Page Defects in HP-UX 11i v3 on the VM Host
With patch PHSS_39784, Integrity VM Version 4.1 supports both 64KB and 4KB settings for the
base_pagesize tunable, but the installation of Integrity VM automatically configures the
base_pagesize tunable (see the kctune(1m) manpage), so that the VM Host's operating system
uses 64K memory pages. This significantly improves the efficiency of Integrity VM's memory
management on behalf of the virtual machines. Unfortunately, there are several defects that can
significantly hamper software installation and operation when HP-UX is configured with 64K
base_pagesize (BPS).
NOTE: Using a 64KB base_pagesize instead of 4KB saves approximately 700 MB on a 2 GB
system.
This section highlights some of the more common and severe problems. For the latest issues
related to 64K BPS, see the Integrity Virtual Machines Platform Manager section of the white
paper Tunable Base Page Size, the latest version of which is available from Tunable Base Page Size.
To avoid these problems, you can change the base_pagesize on the VM Host to 4K.
NOTE: In Integrity VM V4.2, the 64KB base_pagesize is no longer set by default during
installation.
2.3.2.1 HP-UX Installation and Update Failures When Using Physical Installation Media
The update from 0903 OE media might fail on VM Host (physical) systems, leaving the operating
system in an unusable state. This is caused by a defect in HP-UX when running with a
base_pagesize of 64K. Installation of Integrity VM sets the base_pagesize (BPS) to 64K, and
Integrity VM Version 4.1 requires HP-UX 0903 on the VM Host system. The failure manifests in
at least two ways:
