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

NOTE:
MORE is available only for LVM Version 2.1 volume groups. For earlier versions, you can still use
the Single-Node Online Reconfiguration (SNOR) method. This method works on all LVM versions and
requires the deactivation of the volume group on all but one node in a cluster. For more information,
see the white paper SLVM Online Volume Reconfiguration at http://www.hp.com/go/
hpux-core-docs —> HP-UX 11i v3 —> white papers.
Support for Cluster Interconnect Subnet Monitoring
Cluster Interconnect Subnet Monitoring can be used to monitor SGeRAC cluster communication subnets
that are configured into Serviceguard multi-node packages. You configure it by means of the
Serviceguard package configuration parameter CLUSTER_INTERCONNECT_SUBNET. Note the
following restrictions:
• Cluster Interconnect subnet monitoring can support up to 4 nodes.
• Only one CLUSTER_INTERCONNECT_SUBNET can be specified per multi-node package.
The CLUSTER_INTERCONNECT_SUBNET parameter works similarly to the SUBNET parameter, which
is still supported for legacy packages. See Chapter 6 of the latest version of Managing Serviceguard
at www.hp.com/go/hpux-serviceguard-docs —> HP Serviceguard —> User guide
for a discussion of legacy versus modular packages.
NOTE:
CLUSTER_INTERCONNECT_SUBNET is available for both modular and legacy packages.
The major difference is that the failure of a subnet being monitored via SUBNET halts the instance of
the package on the node where the subnet has failed. If a subnet fails when it is being monitored via
CLUSTER_INTERCONNECT_SUBNET, SGeRAC simply ensures that at least one instance of the
package remains running in the cluster.
NOTE:
SGeRAC supports both IPv4 and IPv6 for an CLUSTER_INTERCONNECT_SUBNET, but you need to
make sure that your version of Oracle RAC also supports IPv6 for this type of subnet.
Support for Veritas CFS and CVM Versions 5.0 and 5.0.1
SGeRAC A.11.18 and A.11.19 on HP-UX 11i v2 and 11i v3 support Veritas VxVM, CVM and CFS
