Managing Serviceguard Extension for SAP on Integrity Linux, December 2005

Understanding Serviceguard Extension for SAP on Integrity Linux
Planning the LVM Layout for Clustered SAP Environments
Chapter 130
Database and SAP instances depend on the availability of
/sapdb/programs. To minimize dependencies between otherwise
unrelated systems, it is strongly recommended to use a dedicated
SAPNFS package, especially in case that the cluster has additional SAP
application servers installed, more than one SAPDB is installed or the
database is based on the two package concept with DB and CI for mutual
failover. Keeping local copies is possible, though not recommended
because of the fact that there are no administration tools that keep track
of the consistency between the local copies of these files on all the
systems. For more detailed information on LVM setup and distribution
refer to the Managing HP Serviceguard for Linux manual.
