What’s In this Version
HP SGeSAP/LX IPF A.01.01 is the initial release certified on HP Integrity Servers. This
version provides support for the following Serviceguard package types:
• db packages: This package type provides HA failover capabilities for single-instance
ORACLE RDBMS technology. It is usually enhanced with a HA NFS service.
• ci packages: This package type provides HA failover capabilities for SAP WAS Central
Instances and associated SAP processes.
• dbci packages: This package type is a combination of a db package and a ci package and
provides HA failover capabilities for SAP Central System installations based on ORACLE
RDBMS technology. This package type is usually enhanced with HA NFS services.
Supported configurations include:
• Mutual failover solutions using a multinode cluster with multiple db and ci packages. The
cluster node limitation for HP SGeSAP/LX IPF is equal to the current node limitation
given by Serviceguard for Linux for Integrity.
• Idle standby solutions using a dbci package that may fail over to an idle host.
• Failover of a dbci package to a host that has one or more additional SAP Application
Servers installed that need to be shut down during failover to free up resources to the
failing application.
• Failover of a dbci package to a host that has one or more additional SAP components
installed that need to be shut down during failover to free up resources for the failing
application. This includes scenarios that shut down SAP consolidation and/or
development systems.
• A separate Serviceguard package that exclusively provides HA NFS services in a
multi-instance cluster setup.
• Restart of all redundant, non-packaged SAP application servers can optionally be
configured as part of the package startup.
• Consolidation of more than one HA SAP component within a single cluster.
