Solaris I/O Multipathing Features

FSPM consists of a daemon that runs on the host system along with the Solaris Input/Output (I/O) multipathing features. These features prevent multiple paths from being presented as multiple drives. Every Oracle FS System LUN that is configured with multipath access is presented to the operating system as a single drive.

The Solaris I/O multipathing features driver supports failover and failback across redundant paths. The FSPM daemon uses the control path to send and receive information about the hosts. The daemon runs at the user level as a background process to perform management tasks. The daemon sends host attributes to the Pilot. The Solaris I/O multipathing features take control of the paths, hide the actual paths from the operating system, and present a single virtual path to each LUN.

Note: For more information on the Solaris I/O multipathing features, refer to the documentation that corresponds to your Oracle Solaris version. The documentation is listed in the following table.
