The NFS Lock Failover feature is available for local file systems. If you configure NFS Lock Failover for a file system and the file system subsequently fails, then both the file system and its NFS locks will failover to the same node.
The following preliminary settings are necessary before using this feature:
You must have a shared disk accessible to all the nodes in the cluster.
You must prepare a dedicated directory to operate NFS Lock Failover. Do not specify an existing directory. The dedicated directory is used for NFS Lock Failover only. Therefore, if an existing directory is specified, they cannot be used in other applications.
You must reserve one IP address for each application that uses NFS Lock Failover. You will specify this IP address when you configure the local file system for NFS Lock Failover. You will also configure this address in an Ip Address subapplication so it switches with the application that contains the file system.
Note
Only one file system per userApplication object can be selected for NFS Lock Failover.
