Serviceguard Extension for RAC Version A.11.18 Release Notes, 3rd Edition, April 2008

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.
