Enabling Highly Available Local File Systems (5/02)

The following feature was introduced in the Sun Cluster 3.0 5/02 update release and applies to this update and all subsequent updates to Sun Cluster 3.0 software.

The HAStoragePlus resource type can be used to make a local file system highly available within a Sun Cluster environment. The local file system partitions must reside on global disk groups with affinity switchovers enabled and the Sun Cluster environment must be configured for failover. This enables the user to make any file system on multi-host disks accessible from any host directly connected to those multi-host disks. Using a highly available local file system is strongly recommended for some I/O intensive data services, and configuring the HAStoragePlus resource type has been added to the Registration and Configuration procedures in the Sun Cluster Data Services Installation and Configuration Guide.
