This procedure describes how application resource groups are created for NFS. This procedure is specific to this application and cannot be used for another type of application.
Before You Begin
Complete the procedure How to Create a Replication Resource Group on the Secondary 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.
nodeA# clresourcetype register SUNW.nfs
nodeA# clresourcetype register SUNW.HAStoragePlus
nodeA# clresourcegroup create \ -p Pathprefix=/global/etc \ -p Auto_start_on_new_cluster=False \ -p RG_affinities=+++devgrp-stor-rg \ nfs-rg
Specifies the 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 with which 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 action breaks the collocation requirement.
The name of the application resource group.
nodeA# 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 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.
For more information about these extension properties, see the SUNW.HAStoragePlus(5) man page.
nodeA# clreslogicalhostname create -g nfs-rg \ lhost-nfsrg-prim
The logical hostname of the application resource group on the primary cluster is named lhost-nfsrg-prim.
nodeA# clresourcegroup online -M -n nodeA nfs-rg
Brings the resource group online.
Enables the associated resources.
Manages the resource group.
Specifies the node on which to bring the resource group online.
The name of the resource group.
nodeA# clresourcegroup status
Examine the resource group state field to determine whether the application resource group is online for nodeA and nodeB.
