Figure 45 shows a representative multiple-bus failover configuration. Restricting
the access of unit D101 to host BLUE can be done by enabling only the
connections to host BLUE. At least two connections must be enabled for
multiple-bus failover to work. For most operating systems, it is desirable to have
all connections to the host enabled. The example system, shown in Figure 45,
contains three non-clustered HP hosts. Port 1 link is separate from port 2 link
(that is, ports 1 of both controllers are on one loop or fabric, and port 2 of both
controllers are on another). Therefore, each adapter has two connections. The
target numbers represent what the third number of the disk number is. For
example, if the disk number is disk10200, 2 is the target number.
