Enabling Highly Available Local File Systems

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

Note - Local file systems include UFS, QFS, and 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 Planning and Administering Data Services for Oracle Solaris Cluster 4.4 contains information about configuring the SUNW.HAStoragePlus resource type.
