Serviceguard Extension for RAC Version A.11.18 Release Notes, 2nd Edition, December 2007

Serviceguard Extension for RAC Version A.11.18 Release Notes
What’s in this Version
Chapter 110
• Starting with version A.11.17, all log messages from cmgmsd will log
to /var/adm/syslog/syslog.log by default.
• All nodes in the cluster must be either SGeRAC nodes or
Serviceguard nodes. Also, SGeRAC cluster must have SGeRAC
software installed on all nodes. SGeRAC version A.11.17 and later
will enforce this homogeneity requirement at cluster creation and
formation.
NOTE The enhancement in version A.11.17 or later will perform the
homogeneity check to verify the nodes are either all SGeRAC or
Serviceguard nodes without any manual intervention.
For versions prior to A.11.17, there is no homogeneity check during a
rolling upgrade to A.11.17.
• Rolling upgrade is not supported from releases prior to version
A.11.15
• SGeRAC does not support a rolling upgrade from Cluster Volume
Manager (CVM) version 3.5 to either Cluster Volume Manager
(CVM) version 4.1 or 5.0.
• SGeRAC does not support a rolling upgrade from Cluster Volume
Manager (CVM) version 4.1 to Cluster Volume Manager (CVM)
version 5.0.
• Serviceguard Extension for RAC does not support Mixed Clusters.
All cluster nodes must be either HP 9000 or HP Integrity servers, but
not both in the same cluster.
•Fixes
NOTE Cross-subnet, a new Serviceguard feature introduced in PHSS_37094 on
11i v2 and PHSS_37095 on 11i v3, is currently not supported with
SGeRAC.
