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 UFS and ZFS. 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.
The cluster file systems configured in the HAStoragePlus resource type for zone clusters should be authorized for use in zone clusters by using the clzonecluster command. For more information, see the clzonecluster(8CL) man page and How to Add a Cluster File System to a Zone Cluster (clsetup) in Installing and Configuring an Oracle Solaris Cluster 4.4 Environment.
