After installation of NEC Storage PathManager is complete and connection is established between the
server and NEC Storage, NEC Storage PathManager automatically recognizes disk subsystems and paths.
Then operation starts. From then on, NEC Storage PathManager automatically starts up when the system
starts up, and it automatically stops when the system stops. When the system starts up, NEC Storage
PathManager automatically groups paths for each logical unit and conceals the paths in applications (to make
only one path visible).
Use an spscmd to check current NEC Storage PathManager operation status such as path state display and
path control. Refer to "Chapter 3 Functions of NEC Storage PathMana ger" for the spscmd.
