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.
nodeC# clresourcetype register SUNW.nfs
nodeC# clresourcetype register SUNW.HAStoragePlus
nodeC# clresourcegroup create \ -p Pathprefix=/global/etc \ -p Auto_start_on_new_cluster=False \ -p RG_affinities=+++devgrp-stor-rg \ nfs-rg
Creates the resource group.
Specifies a property of the resource group.
Specifies a directory into which the resources in the group can write administrative files.
Specifies that the application resource group is not started automatically.
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.
The name of the application resource group.
nodeC# clresource create -g nfs-rg \ -t SUNW.HAStoragePlus \ -p FileSystemMountPoints=/global/mountpoint \ -p AffinityOn=True \ nfs-dg-rs
Creates the resource.
Specifies the resource group to which the resource is added.
Specifies that the resource is of the type SUNW.HAStoragePlus.
Specifies a property of the resource.
Specifies that the mount point for the file system is global.
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.
The name of the HAStoragePlus resource for the NFS application.
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.
nodeC# clresource create -g nfs-rg \ -t SUNW.nfs -p Resource_dependencies=nfs-dg-rs nfs-rg
nodeC# umount /global/mountpoint
If the volume is mounted on a secondary cluster, the synchronization fails.
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.
