Figure 7–1. Example storage map
The example system shown in Figure 7–2, contains three non-clustered TRU64_UNIX
hosts. The port 1 link is separate from the 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.
From the hosts’ point of view, each host will have four paths to its own virtual disks.The
figure 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.
