HP Integrity Virtual Machines 4.3: Installation, Configuration, Administration

NOTE: Dynamic Root Disk (DRD), an HP-UX system administration toolset, is available to
clone an HP-UX system image to an inactive disk for software maintenance or recovery. The
bundle name is DynRootDisk and the product name is DRD. Administrators can use DRD to
reduce downtime for system maintenance by creating an inactive clone of the booted system,
then applying patches and products to the clone. The modified clone can then be booted at a
convenient time. DRD is available for download from a software depot. For information about
HP-UX Dynamic Root Disk, see HP-UX 11i v3 Documentation.
2.3.2 Analyze HP-UX 11i v2 based Integrity VM Server
Analyzing HP-UX 11i v2 based Integrity VM server is the most important stage of the Integrity
VM server upgrade. During this analysis, it is important to discover any incompatible hardware
and software subsystems. You can use the HP-UX 11i v2 to 11i v3 Mass Storage Check Utility
(msv2v3check ) and the Integrity VM hpvmupgrade tool to assist in the analysis.
The msv2v3check tool is free software provided on the http://software.hp.com website. Go to
this website, search for msv2v3check, and download this free tool.
The hpvmupgrade tool is provided with Integrity VM V4.3. Use one of the following ways to
obtain this tool:
• Download VMGuestLib from the http://software.hp.com website and follow the instructions
documented there.
• Install VMGuestLib from HP-UX 11i v2 AR media, September 2008 or later.
These analysis utilities are aimed primarily at mass storage problems and problems that are
specific to existing virtual machines. In most cases, you can take actions to resolve these
incompatibilities before doing the upgrade, such as loading new firmware. Other solutions might
require waiting until after the upgrade, such as substituting agile devices for an 11i v2 multipath
solution. Another area of particular concern is the layered products running on your 11i v2 based
Integrity VM server. Analyze each layered product to determine its upgrade impact:
• No change - Layered product is compatible.
• Delete/reinstall - Layered product requires a new version to work on 11i v3.
• Delay upgrade – Layered product needs a new version that has not yet released.
For more information, see the HP-UX 11i v3 documentation on the BSC website at: HP-UX 11i
v3 Manuals.
2.3.2.1 Run the HP-UX msv2v3check Tool
The HP-UX msv2v3check command reviews all mass storage controllers and devices on your
system for HP-UX 11i v3 compatibility and support. In addition, msv2v3check attempts to
verify that your system meets other 11i v3 system requirements, particularly the minimum
memory required and supported platforms. For more information , see the getconf (1M) and
model (1M) HP-UX commands.
The msv2v3check command looks at only mass storage controllers (host bus adapters) and
devices for HP-UX 11i v3 compatibility and support. This includes the following:
• Ultra0 SCSI (C8xx) host bus adapters and attached HP supported SCSI devices
• Ultra320 SCSI (MPT) host bus adapters and attached HP supported SCSI devices
• Serial Attached SCSI (SAS) host bus adapters and attached HP supported SAS devices
• Smart Array RAID (CISS) host bus adapters and attached HP supported RAID devices
• Fibre Channel (FCD/TD) host bus adapters and attached HP supported Fibre Channel devices
• HP supported SCSI disk enclosures and arrays
• HP supported Fibre Channel disk enclosures and arrays
The msv2v3check command creates the following log file in the /var/adm/msv2v3check/
directory:
