### How to Create an NFS Application Resource Group on the Secondary Cluster

Before You Begin

- Complete the procedure How to Create an NFS Application Resource Group on the Primary Cluster.

- Ensure that the `/etc/netmasks` file has IP-address subnet and netmask entries for all logical hostnames. If necessary, edit the `/etc/netmasks` file to add any missing entries.

1. Access `nodeC` as the role that provides `solaris.cluster.modify`, `solaris.cluster.admin`, and `solaris.cluster.read` RBAC authorization.
2. Register `SUNW.nfs` as a resource type.

       nodeC# clresourcetype register SUNW.nfs

3. If `SUNW.HAStoragePlus` has not been registered as a resource type, register it.

       nodeC# clresourcetype register SUNW.HAStoragePlus

4. Create an application resource group for the device group.

       nodeC# clresourcegroup create \
       -p Pathprefix=/global/etc \
       -p Auto_start_on_new_cluster=False \
       -p RG_affinities=+++devgrp-stor-rg \
       nfs-rg

   `create`

     Creates the resource group.

   `-p`

     Specifies a property of the resource group.

   `Pathprefix=/global/etc`

     Specifies a directory into which the resources in the group can write administrative files.

   `Auto_start_on_new_cluster=False`

     Specifies that the application resource group is not started automatically.

   `RG_affinities=+++devgrp-stor-rg`

     Specifies the resource group where the application resource group must be collocated. In this example, the application resource group must be collocated with the replication resource group `devgrp-stor-rg`.

     If the replication resource group is switched over to a new primary node, the application resource group is automatically switched over. However, attempts to switch over the application resource group to a new primary node are blocked because that breaks the collocation requirement.

   `nfs-rg`

     The name of the application resource group.

5. Add a `SUNW.HAStoragePlus` resource to the application resource group.

       nodeC# clresource create -g nfs-rg \
       -t SUNW.HAStoragePlus \
       -p FileSystemMountPoints=/global/mountpoint \
       -p AffinityOn=True \
       nfs-dg-rs

   `create`

     Creates the resource.

   `-g`

     Specifies the resource group to which the resource is added.

   `-t SUNW.HAStoragePlus`

     Specifies that the resource is of the type `SUNW.HAStoragePlus`.

   `-p`

     Specifies a property of the resource.

   `FileSystemMountPoints=/global/mountpoint`

     Specifies that the mount point for the file system is global.

   `AffinityOn=True`

     Specifies that the application resource must perform an affinity switchover for the global devices and cluster file systems defined by `-p FileSystemMountPoints=`. Therefore, when the application resource group fails over or is switched over, the associated device group is switched over.

   `nfs-dg-rs`

     The name of the HAStoragePlus resource for the NFS application.

6. Add a logical hostname resource to the application resource group.

       nodeC# clreslogicalhostname create -g nfs-rg \
       lhost-nfsrg-sec

   The logical hostname of the application resource group on the secondary cluster is named `lhost-nfsrg-sec`.

7. Add an NFS resource to the application resource group.

       nodeC# clresource create -g nfs-rg \
       -t SUNW.nfs -p Resource_dependencies=nfs-dg-rs nfs-rg

8. If the global volume is mounted on the primary cluster, unmount the global volume from the secondary cluster.

       nodeC# umount /global/mountpoint

   If the volume is mounted on a secondary cluster, the synchronization fails.

### Example of How to Enable Data Replication

This section describes how data replication is enabled for the example configuration. This section uses the Availability Suite software commands `sndradm` and `iiadm`. For more information about these commands, see the Availability Suite documentation.
