Serviceguard Extension for RAC Version A.11.17 Release Notes, December 2005

Serviceguard Extension for RAC Version A.11.17 Release Notes
What’s in this Version
Chapter 18
• Support for Cluster File System (CFS) version 4.1 and Cluster
Volume Manager (CVM) version 4.1 in clusters up to 4 nodes.
• Support for Cluster Volume Manager (CVM) version 3.5 in clusters
up to 8 nodes.
• Support for a maximum of 16-nodes in a cluster when Shared LVM is
used.
• When using HP Serviceguard Cluster File System for RAC,
(T2777BA) or HP Serviceguard Cluster File System for RAC with
MCOE (T2797BA), single instance Oracle is not supported if instance
startup and shutdown is outside of Serviceguard package control.
• 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 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 Cluster Volume Manager (CVM)
version 4.1.
• SGeRAC does not support mixed clusters. All cluster nodes must be
either HP 9000 or HP Integrity servers, but not both in the same
cluster.
