Managing Serviceguard Extension for SAP Version B.05.10, September 2010

file system can only be mounted exclusively and accessed from the cluster node running
the Serviceguard package though.
• NFS client: All cluster nodes mount the file system as NFS clients at the same time.

/home/mo7adm
In this configuration the /home/mo7adm directory is local on each cluster node and will not
relocate. It contains environment profiles for the MDM administrator user. Note that if desired
/home/mo7adm could also have been setup as a Serviceguard NFS service, but for this installation
a local configuration was chosen.
/usr/sap
Contains SAP directories and files for the different SAP instances.
/usr/sap/MO7/SYS
Contains the SAP directories exe, gen, global, profile and src for SAP system MO7.
/usr/sap/MO7/MDS01
/usr/sap/MO7/MDIS02
/usr/sap/MO7/MDSS03
These directories are on local and relocatable storage and contain log and working directories
for the MDM server components.
/sapmnt/MO7
/export/sapmnt/MO7
The /sapmnt/MO7 directory is required on every cluster node a MDS, MDIS or MDSS component
can run on. It is configured on all cluster nodes as an NFS client mount point and shared by
these. The NFS server in the cluster exports it under the directory /export/sapmnt/MO7. The
directory /export/sapmnt/MO7 is based on local and relocateable storage. It contains the MDM
executables and the SAP MDM instance profiles.
/oracle/client
/export/oracle/client
The MDS component can be configured to run in a separate Serviceguard package or an combined
package with the MDM database. If it is configured as a separate package, MDS requires the
Oracle client libraries for accessing the database. The directory /oracle/client is configured
as a NFS client point and shared by all cluster nodes. The NFS server in the cluster exports it
under the directory /export/oracle/client.
