The HAStoragePlus resource type is designed to make local and global file system configurations highly available. You can use the HAStoragePlus resource type to integrate your shared local or global file system into the Oracle Solaris Cluster environment and make the file system highly available.
Oracle Solaris Cluster systems support the following cluster file system:
UNIX File System (UFS) – Uses Oracle Solaris Cluster Proxy File System (PxFS)
Oracle Solaris Cluster software supports the following as highly available failover local file systems:
Oracle Solaris ZFS (default file system)
Sun QFS Shared file system
Oracle Automatic Storage Management Cluster File System (Oracle ACFS) - Integrates with Oracle ASM and Oracle Clusterware (also referred to collectively as Oracle Grid Infrastructure)
The HAStoragePlus resource type provides additional file system capabilities such as checks, mounts, and forced unmounts. These capabilities enable Oracle Solaris Cluster to fail over local file systems. In order to fail over, the local file system must reside on global disk groups with affinity switchovers enabled.
See Enabling Highly Available Local File Systems in Oracle Solaris Cluster Data Services Planning and Administration Guide for information about how to use the HAStoragePlus resource type.
You can also use the HAStoragePlus resource type to synchronize the startup of resources and device groups on which the resources depend. For more information, see Resources, Resource Groups, and Resource Types.
