-> High Availability -> Serviceguard
• There are operating-system dependencies; see “Operating-System Dependencies”
(page 8) and“Announcements for HP-UX 11i v3”.
• Serviceguard version A.11.19 must be installed as a prerequisite product for
SGeRAC version A.11.19. (See the latest version of the Serviceguard Version A.11.19
Release Notes at the address given above for more information about Serviceguard.)
• Version A.11.19 of SGeRAC permits a maximum of 16 HP 9000 or HP Integrity
servers configured as a high availability cluster. Multiple Oracle databases on the
same node are supported.
• All nodes in the cluster must be either SGeRAC nodes or Serviceguard nodes. An
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: Version A.11.17 or later will perform the homogeneity check without any
manual intervention.
There is no homogeneity check during a rolling upgrade to A.11.17.
• Rolling upgrade restrictions:
— Rolling upgrade is not supported from releases prior to version A.11.15.
— SGeRAC does not support a rolling upgrade from Cluster Volume Manager
from Symantec (CVM) in any of the following cases:
◦ CVM version 3.5 to CVM version 4.1, 5.0, or 5.0.1
◦ CVM version 4.1 to CVM version 5.0 or 5.0.1
◦ CVM version 5.0 to CVM version 5.0.1
• Online package reconfiguration restriction:
SGeRAC does not support online configuration changes to any SGeRAC Toolkit
parameters in an SGeRAC Toolkit package. It does support online changes to
Serviceguard parameters in all cases that Serviceguard itself supports.
See also “Support for the SGeRAC Toolkit ” (page 15).
