Serviceguard version A.11.20 must be installed as a prerequisite product for SGeRAC version
A.11.20. Or, if the correct version of Serviceguard is not installed on the system, but present
on the media from which SGeRAC is going to be installed, Serviceguard will be selected for
the installation as well. (See the latest version of the Serviceguard Version A.11.20 Release
Notes at the address given above for more information about Serviceguard.)
Version A.11.20 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.
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.
Requirements for Rolling Upgrade to A.11.20.
To perform a rolling upgrade to SGeRAC A.11.20, you must be running the following:
HP-UX 11i v3
SGeRAC A.11.19
If you are not already running A.11.19, you may be able to do a rolling upgrade to A.11.19,
and from A.11.19 to A.11.20.
IMPORTANT: You can upgrade to SGeRAC A.11.19 while using HP-UX 11i v2. But, to
upgrade to SGeRAC A.11.20, you must upgrade to HP-UX 11i v3 first.
Other Rolling upgrade restrictions:
Rolling upgrade is only supported on HP-UX 11i v3.
Refer to Oracle documentation if the rolling upgrade involves an Oracle RAC version
upgrade.
For more information, see the HP-UX 11i v3 version of the HP Serviceguard Storage
Management Suite Release Notes at www.hp.com/go/hpux-serviceguard-docs
> HP Serviceguard Storage Management Suite > Getting started.
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 13).
Operating-System Dependencies
The A.11.20 version of SGeRAC is supported on HP-UX 11i v3.
