Configuring an HAStoragePlus Resource for Cluster File Systems

When an HAStoragePlus resource is configured for cluster file systems and brought online, it ensures that these file systems are available. The cluster file system is supported on a root ZFS file system and a nonroot UNIX File System (UFS). The instructions in this section apply to HAStoragePlus resources with UFS. Use HAStoragePlus with local file systems if the data service is I/O intensive. See How to Change the Cluster File System to Local File System in an HAStoragePlus Resource for information about how to change the file system of an HAStoragePlus resource.

The cluster file systems can be configured for zone clusters in the HAStoragePlus resources using the loopback mount mechanism. The SUNW.HAStoragePlus resource type makes the cluster file system available to a zone cluster by mounting the file system in the global cluster. The resource type then performs a loopback mount on the zone cluster nodes where the resource group is online.

Note -  If you have a failover resource group, the resource group will be online on only one node. If you use a scalable resource group, the Desired_primaries property defines the number of nodes the resource group will have online.

The cluster file systems configured in the HAStoragePlus resource type for zone clusters should be authorized for use in zone clusters using the clzonecluster command. For more information, see the clzonecluster(1CL) man page and How to Add a Cluster File System to a Zone Cluster (clsetup) in Oracle Solaris Cluster Software Installation Guide .
