HP Serviceguard Storage Management Suite Version A.02.01 for HP-UX 11iv3 Release Notes, Edition 2 (May 2010)

The recovery operation is I/O intensive and can be time consuming, depending on the number
of volumes and how large they are. In a clustered environment the IO performance of multiple
nodes using the same volume will be impacted during recovery.
HP strongly recommends that you use DRL with mirrored data volumes in a clustered
environment to enable faster volume recovery. However, Oracle database volumes should be
configured without DRL, because the Oracle database application keeps its own logs and does
not require VxVM to maintain logs. For information on DRL and the Veritas™ SmartSync Recovery
Accelerator, see the Veritas™ Volume Manager Administrator’s Guide, HP-UX 11i v3, 5.0.
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
(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 OE version relies on specific versions of HP Serviceguard and Enterprise Cluster Master
Toolkit (ECMT) that can change with new HP-UX 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 OE version that is not supported with the
versions of Serviceguard and ECMT included with the HP-UX OE, swinstall will detect the
incompatible software and the installation will fail.
The software on the HP-UX OE DVD is installed using update-ux. If a SG SMS OE bundle is
installed on your system and you attempt to install or upgrade to an HP-UX OE version that
includes Serviceguard and ECMT versions that are not supported with the SG SMS OE bundle,
update-ux will detect the incompatible software.
To avoid these potential installation conflicts, always upgrade the HP-UX OE and the SG SMS
OE bundle simultaneously as described in “Updating HP-UX and SG SMS Simultaneously”
(page 34).
If the HP-UX OE upgrade you want to install is not supported with the Serviceguard and ECMT
versions in the SG SMS bundle that is installed on your system, you must upgrade to an SG SMS
OE bundle that is supported with the HP-UX OE version you want to install.
See “Compatibility Information and Installation Requirements” (page 24) for more information
on bundle upgrades.
