Serviceguard Extension for SAP Version B.06.00.20 Release Notes for Linux, March 2014

SAP-specific node-local cluster verification
SGeSAP maintains a list of rules that specify local configuration requirements on potential secondary
nodes. These requirements are checked with every execution of the cmcheckconf(1m) or
cmapplyconf(1m) commands on a modular-style SGeSAP package. Use of cmcheckconf(1m)
command for a SGeSAP package that is in a running condition helps to detect erroneous local
configurations that negatively impacts the capability to failover a SGeSAP package to a certain
node.
SAP HANA scale-up system replication
SGeSAP supports scale-up HANA system replication High Availability and Disaster Recovery
clusters with synchronous or asynchronous replication. The cluster automates HANA instance
startup, shutdown, monitoring, restart, re-initialization of corrupted replications, takeover, and
role-reversal operations. The failover node can be utilized with additional non-production HANA
instances that will be halted as part of a takeover operation. To support HANA database clusters,
SGeSAP provides new cluster modules sgesap/hdbinstance, sgesap/hdbprimary, and
sgesap/hdbdualpurpose, the HANA service monitor saphdbsys.mon, extended versions of
the SAP cluster easy deployment tool deploysappkgs(1), and SAP cluster API library
saphpsghalib.so.1.
Changed features
Modular-style HP SGeSAP/LX provides a superset of the functionality of legacy-style HP SGeSAP/LX
and is recommended to be used as its substitute. The modular-style HP SGeSAP/LX package logic
is a new implementation. It varies from the legacy-style package in the logging behavior and
functionality. Modular-style package has extended functionality compared to its legacy-style
equivalent.
The changes maintain compliance with SAP’s Netweaver 7.30/7.40 recommendations.
Legacy-style packages created with HP SGeSAP/LX A.03.00 continue to operate after upgrade
to HP SGeSAP/LX A.6.00. However, new packages must be created as modular-style packages
and the existing packages have to be replaced by modular-style packages as soon as possible.
Deprecated or obsolete features
Serviceguard legacy packaging is not supported in combination with Serviceguard for Linux
A.12.00.00 or higher. Existing legacy SGeSAP/LX configurations must be migrated to modular-style
SGeSAP/LX packages before upgrading to Serviceguard for Linux A.12.00.00.
The deploysappkgs(1) tool can be used to create modular-style package configuration files
for existing HP SGeSAP/LX A.03.00 legacy clusters. The command can be used in place of a
formal SGeSAP package migration tool for the mandatory software cluster components.
SGeSAP Livecache and SAP infrastructure package functionality needs to be manually recreated
in modular style using the guided package creation or the package edit dialog screens of HP
Serviceguard Manager.
Discontinued releases of SGeSAP on Linux
