Enabling Highly Available Local File Systems

You can use the HAStoragePlus resource type to make a local file system highly available within an Oracle Solaris Cluster environment.

Note - Local file systems include the UNIX File System (UFS) and Oracle Solaris ZFS.

The local file system partitions must be located on global disk groups. Affinity switchovers must be enabled, and the Oracle Solaris Cluster environment must be configured for failover. This setup enables the cluster administrator to make any file system that is located on multihost disks accessible from any host that is directly connected to those multihost disks. You use a highly available local file system for selected I/O intensive data services. Enabling Highly Available Local File Systems in Oracle Solaris Cluster Data Services Planning and Administration Guide contains information about configuring the HAStoragePlus resource type.
