Using Easy Deployment in Serviceguard and Metrocluster environments on HP-UX 11i v3

Automatic Package Dependency configuration for Oracle Clusterware storage

If there are no disk group (DG-MNP) and mount point (MP-MNP) packages already configured for the

storage being used by the Oracle Clusterware files, the packages will be configured automatically.

The dependency between the Oracle Clusterware package and the mount point and disk group

packages will also be established. The following illustration in Figure 15 provides more details on the

dependency structure for Oracle Clusterware, Oracle RAC database, and mount point and disk group

packages:

Figure 15: SGeRAC dependency structure

The CFS-DG-MP-MNP1 package manages the mount points and disk groups associated with the

Oracle Clusterware package. The Oracle Clusterware package needs its associated storage to be up,

and for this reason it needs to be dependent on the CFS-DG-MP-MNP1 package.

Similarly, the CFS-DG-MP-MNP2 package manages the mount points and disk groups associated with

the Oracle RAC DB package. The RAC DB package again needs its associated storage to be up, and

for this reason it needs to be dependent on the CFS-DG-MP-MNP2 package.

The SG-CFS-pkg (SMNP) is responsible for configuring and starting the CVM/CFS stack. The CFS-DG-

MP-MNP1 and the CFS-DG-MP-MNP2 packages need CVM to be configured and running, and for

this reason these packages need to be dependent on the SG-CFS-pkg (SMNP).

If a separate storage has been used for Oracle Clusterware software, then the storage information

will be populated in the package configuration, so that the user is freed from having to activate the

volumes, mount the file system, etc. This will be taken care of as part of the Oracle Clusterware

package Easy Deployment.

Parameter discovery and default parameters

By way of automatic package parameter discovery by the Easy Deployment operation, the following

Oracle Clusterware package attributes are automatically populated in the corresponding

configuration file:

• Cluster nodes

• Oracle Clusterware Home path
