Sun Cluster Data Service for Sun Java System Message Queue Guide for Solaris OS

Configuring the 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 the data service.

SUNW.HAStoragePlus also has an additional feature to make a local file system highly available. Sun Cluster HA for Sun Java System Message Queue is not disk intensive and not scalable, and therefore setting up the SUNW.HAStoragePlus resource type is optional.

See the SUNW.HAStoragePlus(5) man page and “Relationship Between Resource Groups and Disk Device Groups” in Sun Cluster Data Services Planning and Administration Guide for Solaris OS for background information. See “Synchronizing the Startups Between Resource Groups and Disk Device Groups” in Sun Cluster Data Services Planning and Administration Guide for Solaris OS 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.
