How to Configure SUNW.HAStoragePlus Resource Type

The SUNW.HAStoragePlus resource type was introduced in Sun Cluster 3.0 5/02. This new resource type performs the same functions as SUNW.HAStorage, and synchronizes actions between HA storage and Sun Cluster HA for NFS. SUNW.HAStoragePlus also has an additional feature to make a local file system highly available. Sun Cluster HA for NFS is both failover and disk-intensive, and therefore, you should set up the SUNW.HAStoragePlus resource type.

See the SUNW.HAStoragePlus(5) man page and “Relationship Between Resource Groups and Disk Device Groups” in Sun Cluster 3.1 Data Service Planning and Administration Guide for background information. See “Synchronizing the Startups Between Resource Groups and Disk Device Groups” in Sun Cluster 3.1 Data Service Planning and Administration Guide for the procedure. (If you are using a Sun Cluster 3.0 version prior to 5/02, you must set up SUNW.HAStorage instead of SUNW.HAStoragePlus. See “Synchronizing the Startups Between Resource Groups and Disk Device Groups” in Sun Cluster 3.1 Data Service Planning and Administration Guide for the procedure.)
