Serviceguard Extension for RAC Version A.11.18 Release Notes, 1st Edition, June 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 a cluster running SGeRAC must have SGeRAC
installed. Mixed clusters of Serviceguard/SGeRAC are not supported.
Starting with Serviceguard/SGeRAC version A.11.17 this
homogeneity requirement is enforced 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.
Mixed clusters. All cluster nodes must be either HP 9000 or HP
Integrity servers, but not both in the same cluster.
