Multipathing
Multipathing is the process of providing a server more than one path to a storage system, so that in
the case of an emergency, the server will have continuous access to the storage system.
Multipathing can be done many ways. For example, you can provide redundant switches for a host
to access a storage system. Another example of multipathing is providing redundant paths from the
host to the switch. To determine if your multipathing software is supported, refer to the release notes.

server to obtain RDAC information.
