4.1.2 Analyzing 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 incompatible hardware and software

subsystems, if any.

HP-UX 11i v3 uses a mass storage model called the agile device reference model, for naming and

identifying devices. The 11i v2 model is called the legacy device reference model. The agile device

model uses worldwide device identifiers (WWIDs) to identify devices. The WWID is a device

attribute that is independent of the location of the device in a SAN or in an adapter or controller

access path. Therefore, the agile device names are persistent with respect to changes in the access

path, and can utilize multiple paths through a single device name.

The legacy devices require multiple device names to access the same device through multiple paths.

Many Integrity VM customers use multipath solutions such as SecurePath, which allows them to use

a single device name to access all paths. Some of these 11i v2 multipath solutions continue to

work, while others must be removed. After the upgrade is completed, replace the existing multipath

device with the agile device name, with the inherent multipath support.

NOTE: If you are using EMC PowerPath (that supports legacy DSFs alone) for whole disk backing

store, you must migrate to using Native MultiPathing that comes built-in with HP-UX 11.31.

Analyze each layered product to determine the upgrade impact:

• No change - Layered product is compatible.

• Delete or reinstall - Layered product requires a new version to work on 11i v3.

• Delay upgrade – Layered product needs a new version that is not yet released.

For more information about the layered product, see the HP-UX 11i v3 documentation available

at http://www.hp.com/go/hpux-core-docs-11iv3.

4.1.2.1 Running 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. The msv2v3check tool is free software

available on the http://software.hp.com website. Go to this website, search for msv2v3check,

and download this free tool.

The msv2v3check command examines only mass storage controllers (host bus adapters) and

devices for HP-UX 11i v3 compatibility and support. This includes the following:

• Ultra160 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.
