Configuring Oracle Solaris Cluster HA for NFS for Use With HA for Oracle Grid Engine

You must use NFS to export the Oracle Grid Engine file system to the noncluster nodes. The NFS server that exports this file system must also be protected against failure. To protect the NFS server against failure, use the Oracle Solaris Cluster HA for NFS data service.

The procedure that follows explains only the special requirements for using Oracle Solaris Cluster HA for NFS with HA for Oracle Grid Engine. For complete information about installing and configuring Oracle Solaris Cluster HA for NFS, see Oracle Solaris Cluster Data Service for Network File System (NFS) Guide.

How to Configure Oracle Solaris Cluster HA for NFS for Use With HA for Oracle Grid Engine

Note - Commands in this procedure assume that you have set the $SGE_ROOT environment variable to specify the root of the Oracle Grid Engine file system.

Register the SUNW.nfs resource type.
```
# clresourcetype register SUNW.nfs
```
From any cluster node, create a directory for NFS configuration files.
Create the directory under root of the Oracle Grid Engine file system. Name the directory SUNW.nfs.
```
# mkdir -p $SGE_ROOT/SUNW.nfs
```
In the directory that you created in Step 2, create a file that contains the share command for the root of the Oracle Grid Engine file system.
Name the file the dfstab.sge-nfs-rs, where sge-nfs-rs is the name of the NFS resource that you will create in Step 4.
```
# echo "share -F nfs -o rw sge-root" \
 > $SGE_ROOT/SUNW.nfs/dfstab.sge-nfs-rs
```
Add a SUNW.nfs resource to the failover resource group that you created in How to Enable Oracle Grid Engine to Run in a Cluster.
```
# clresource create \
-g sge-rg \
-t SUNW.nfs \
-p Resource_dependencies=sge-hasp-rs \
sge-nfs-rs
```

Example 1-2 Creating a dfstab File for the Root of the Oracle Grid Engine File System

This example shows the command for creating a dfstab file for the root of the Oracle Grid Engine file system.

The root of the Oracle Grid Engine file system is /global/gridmaster.
The name of the NFS resource for which this file is created is sge-nfs-rs.

# echo "share -F nfs -o rw /global/gridmaster" \
 > /global/gridmaster/SUNW.nfs/dfstab.sge-nfs-rs
