HP Serviceguard Storage Management Suite Version A.02.00 for HP-UX 11i v3 Release Notes, 2nd Edition, September 2008

HP-UX Operating Environment Upgrade Limitations
When you purchase an HP Serviceguard Storage Management Suite (SG SMS) Operating
Environment (OE) bundle, the SG SMS software is provided on one DVD and the HP-UX OE
(Mission Critical - MCOE, Data Center - DCOE, or High Availability - HAOE) is provided on a
separate DVD.
The software provided on the SG SMS DVD relies on products and filesets that are provided on
the OE DVD, including HP Serviceguard and the Veritas Storage Foundation products. Each SG
SMS version relies on specific versions of HP Serviceguard and the Veritas Storage Foundation
products that can change with new OE releases.
The software on the SG SMS DVD is installed using swinstall. If an HP-UX OE is installed on
your system and you attempt to install a SG SMS version that is not supported with the versions
of Serviceguard and Veritas Storage Foundation included with the OE, swinstall will detect
the incompatible software and the installation will fail.
The software on the OE DVD is installed using update-ux. If a SG SMS bundle is installed on
your system and you attempt to install or upgrade to an OE version that includes Serviceguard
and Veritas Storage Foundation versions that are not supported with the SG SMS bundle,
update-ux will not detect the incompatible software. The installation will complete, but the
Serviceguard cluster will not start, or you will not be able to access the Veritas volumes.
update-ux does not check for software dependencies.
If the OE upgrade you want to install is not supported with the Serviceguard and Veritas Storage
Foundation versions in the SG SMS bundle that is installed on your system, you must upgrade
to an SG SMS bundle that is supported with the OE version you want to install.
See “Compatibility Information and Installation Requirements” (page 23) for more information
on bundle upgrades.

When systems in a SG cluster are under a heavy I/O load, if the CVM master node becomes
I/O bottle necked while processing a reconfiguration request, a pingable hang may occur.
• What is the workaround?
There is no workaround. If a pingable hang occurs, all of the nodes in the cluster will need
