/export/sapmnt/MO7"
nfs/hanfs_export/XFS " -o root=clundode1:clunode2 \
/export/oracle/client"
Register the Serviceguard nfsMO7 package in the cluster and run it:
clunode1
cmapplyconf -P /etc/cmcluster/NFSMO7/nfsMO7.config
cmrunpkg nfsMO7
Setup Step: MDM110
Add /sapmnt/MO7 and /oracle/client to the automounter configuration.
The NFS exported directory will be mounted as a NFS client directory. Edit the file
/etc/auto.direct and add the directories.
vi /etc/auto.direct
/sapmnt/MO7 -proto=udp nfsMO7reloc:/export/sapmnt/MO7
/oracle/client -proto=udp nfsMO7reloc:/export/oracle/client
Distribute /etc/auto.direct to all cluster members with scp.
scp -p /etc/auto.direct clunode2:/etc/auto.direct
Restart nfs subsystem on all cluster members.
/sbin/init.d/autofs stop
/sbin/init.d/autofs start
/sbin/init.d/nfs.client stop
/sbin/init.d/nfs.client start
Creating initial Serviceguard packages for the MDM installation
In this section the goal is to setup an environment to allow the installation of the MDM server
and the database components. The environment is such that initially only the storage volumes,
the file systems and the virtual IP address will be enabled when the Serviceguard package is
started, no SGeSAP functions will executed. So the basic goal is just to provide the file system
space and virtual IP address required by the installation.
The following steps will depend if the MDM Database will be configured as "Single/Central
System" or "Multiple/Distributed" MDM Serviceguard package configuration as described earlier.
• (a) = Single MDM Serviceguard package—create a mcsMO7 package.
• (b) = Multiple MDM Serviceguard packages—create mdbMO7, mdsMO7, mdssMO7, and
mdisMO7 packages.
Setup Step:
Level: MDM200
(a) Single MDM Serviceguard package - create a mcsMO7 package.
