Overview of Solaris I/O Multipathing

The Solaris I/O multipathing features enable multiple access paths for systems that are running the Oracle Solaris OS. Multipathing provides higher availability for storage devices through the use of multipathed connections.

The Solaris I/O multipathing features identify the storage devices on your SAN or SAS Domain. The software enables you to attach Fibre Channel storage devices in either loop, fabric, or point-to-point mode. The software provides a common interface for managing both Fibre Channel and SAS storage.

For information on how to configure targets and initiators in preparation for multipathing, see Chapter 14, Configuring Storage Devices With COMSTAR, in Oracle Solaris Administration: Devices and File Systems.
