Serviceguard Extension for SAP Versions B.04.02 and B.04.51 Release Notes
Compatibility Information and Installation Requirements
Chapter 112
A combination of CFS and HA NFS is possible. CFS simplifies the filesystem layout within
the cluster, NFS provides access to shared filesystems to SAP instances running on servers
outside of the cluster.
SGeSAP supports storage layouts of (S)LVM or VxVM volume managers.
Optionally, SGeSAP is supported in combination with SGeRAC, as well as with Metrocluster
and Continentalcluster.
Hot standby liveCache installations require a combination of LVM volumes and CVM
volumes. They have further software requirements. Hot standby liveCache requires the HP
Serviceguard Cluster Filesystem product to be installed as a mandatory product.
Furthermore the cost-free software HP Storageworks RAIDManager XP Version 1.19.04
(T1610) needs to be downloaded and installed. It can be found on http://software.hp.com.
Compatibility Issues
To achieve a supported SGeSAP integration, perform all installation steps described in the
most recent version of the Managing Serviceguard Extension for SAP manual, part number
T2803-900011. Installation steps might differ slightly from what is described there if a
software component is involved that became supported after the print date of the manual. In
these cases, additional or changed installation instructions can be found in this document.
NOTE Always use the latest SAP kernel patch that is available from SAP.
