Auto Path with MC/ServiceGuard for Linux
HP SureStore Auto Path software lets you define storage units that include redundant storage links. This is
an alternative to the use of the md driver to build mirrored storage. One advantage of Auto Path is the
ability to define load-balancing for performance improvement among the links you have defined.
Auto Path, when installed, provide multiple pathways to the LUNS in your disk arrays. The disk arrays are
cabled to each cluster node using two separate FibreChannel interface cards to provide redundant links to
the data from the node.
