Serviceguard Extension for RAC Version A.11.19 Release Notes (May 2010)

Support for the SGeRAC Toolkit
The SGeRAC Toolkit provides documentation and scripts to simplify the integration of SGeRAC and
the Oracle 10gR2/11gR1/11gR2 RAC stack. It also manages the dependency between Oracle
Clusterware and Oracle RAC instances with a full range of storage management options (CFS, SLVM,
CVM, ASM over SLVM).
• The README file that accompanies the SGeRAC Toolkit, which will be on your system after the
installation as /opt/cmcluster/SGeRAC/toolkit/README.
• Use of Serviceguard Extension for RAC Toolkit with Oracle RAC 10g Release 2 or later at http:/
/www.hp.com/go/hpux-serviceguard-docs —> HP Serviceguard Extension for
RAC —> General reference.
See also “Dependencies and Limitations” on page 3.
Support for toolkit maintenance mode
This feature allows you to perform Oracle OC/ASMDG/RAC maintenance while OC/ASMDG/RAC
multi-node packages are running in the cluster. It is implemented in the SGeRAC Toolkit by means of
the MAINTENANCE_FLAG parameter. See the white paper Use of Serviceguard Extension for RAC
Toolkit with Oracle RAC 10g Release 2 or later, at the address given above, and the SGeRAC Toolkit
README.
NOTE:
This feature is distinct from Serviceguard's package maintenance mode, described in the latest version
of the Serviceguard Version A.11.19 Release Notes , which you can find at the address given under
“Documentation for This Version ” on page 13.
Support for new ASM DG Packages (included in the April 2010 patches)
If you are using ASM over SLVM in a metrocluster environment or in a non-metrocluster environment,
this feature allows you to decouple the ASM disk groups from your OC package, and provides
flexibility to maintain your ASM disk groups independently.
For more information on how to configure and use the ASM DG package, see the README file
included with the SGeRAC Toolkit. After the SGeRAC Toolkit is installed on the system, you can find
the file here: /opt/cmcluster/SGeRAC/toolkit/README.
GMS authorization
GMS prevents unauthorized users from accessing cluster information and registering or de-registering
group memberships. GMS is disabled by default—use the GMS_USER[] parameter in /etc/opt/
nmapi/nmutils.conf to configure it.
Upgrade Using DRD
DRD stands for Dynamic Root Disk. Using a Dynamic Root Disk on HP-UX 11i v3 allows you to perform
the update on a clone of the root disk, then halt the node and reboot it from the updated clone root
disk.
