Enabling Highly Available Local File Systems

You can use the HAStoragePlus resource type to make a local file system highly available within a Sun Cluster environment. The local file system partitions must be located on global disk groups. Affinity switchovers must be enabled and the Sun Cluster environment must be configured for failover. This set up 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. “Enabling Highly Available Local File Systems” in Sun Cluster Data Services Planning and Administration Guide for Solaris OS contains information about configuring the HAStoragePlus resource type.
