The present invention is a system, method, and apparatus for configuring a
host computer to cooperatively operate with a data storage system in a
data storage environment, and includes selective ability to configure a
host adapter globally or specifically according to its topology and/or
connections. This invention provides particular advantages when
configuring a Unix-based host, such as a Sun Solaris computer available
from Sun Microsystems of Santa Clara, Calif., USA in connection with a
data storage system.
