HP Integrity Virtual Machines 4.3: Installation, Configuration, Administration

/var/adm/msv2v3check/mmddyy_hhmm is the full log file that contains all
notes, warnings, and error messages from an invocation of msv2v3check,
where mmddyy_hhmm represents the month, day, year, hours and minutes
at the time the msv2v3check utility was started.
Once the msv2v3check utility has completed, a validation result is displayed that indicates the
number of errors and warnings detected on your system configuration:
• An error is a critical message that indicates that your system does not support HP-UX 11i
v3 in its current configuration. Do not ignore this message.
• A warning indicates a task that might require user action, for example, upgrading the
firmware on a disk device, or manually reviewing the firmware of a Fibre Channel disk
array.
Review all warnings and make the necessary corrections before upgrading to HP-UX 11i v3.
For supported I/O drivers, devices, adapters; see the documentation on the BSC website:HP
Manuals.
2.3.2.2 Run the Integrity VM Upgrade Tool
The Integrity VM upgrade tool, hpvmupgrade, can be run on either an 11i v2 or an 11i v3 system.
This tool focuses on analyzing guest configurations for problems that might cause the guest not
to boot when running on an 11i v3 Integrity VM server. Run this utility during the upgrade
analysis stage.
To run this utility, use the following command:
# hpvmupgrade –e
It produces the following log file:
/var/opt/hpvm/common/hpvmupgrade.current_date_and_time
This log file contains a section for each guest configured on the server and displays the following
message types:
• Warning messages indicate problems that can cause a guest booting problem.
• Error messages indicate problems that can cause a guest problem. For example, if a guest’s
virtual disk is backed by a file or device that does not exist on the 11i v2 system, a warning
is issued because the problem is likely to be the same on the 11i v3 system. If, however, a
guest is using a device associated with a multipath solution that is no longer supported on
11i v3, an error is issued.
The Integrity VM upgrade tool is focused on the devices that are used to back guest virtual
devices. Each guest configuration is queried for its virtual backing storage. The guests device
list is then compared to known multipath solutions, AutoPath, Secure Path, PowerPath PVLinks,
or Veritas DMP devices to detect any dependencies.
Because the 11i v3 storage stack supports native multipath access to devices through the agile
device names, the common solution for old 11i v2 multipath solutions is to remove them and
change the applications to reference the new agile devices.
The upgrade tool also examines guest devices for volume backing storage that was used with
multipath devices for physical storage. If this dependency is found, it is flagged in the log file.
This tool also verifies that the 11i v2 Integrity VM server is at V3.0 or V3.5.
2.3.2.3 Determine HP-UX 11i v3 Memory and System Disk Requirements
Integrity VM V4.3 memory requirements vary depending on the number and size of virtual
machines supported by the Integrity VM server. When upgrading from an 11i v2 Integrity VM
server, use the following steps to determine the amount of memory required for the 11i v3
Integrity VM server:
