Table 10: SHOW CONNECTIONS Command Analysis
Notice the port usage for each connection. In multiple-bus failover mode with remote copy
enabled (that is, a DRM configuration), port 1 on each controller is connected only to HBAs.
Port 2 on each controller is connected only to other controllers. Ports 1 and 2 are reserved ports
for DRM configurations.
Make a note of each adapter’s WWID. The controller adds a new connection entry when any
of the following keys change:
■ Host WWID
■ Adapter WWID
■ Controller host port number
■ Controller WWID
There will be four connections through port 2, labeled A, B, C, and D. In the example in
Table 10, they are BUILDNGBA, BUILDNGBB, BUILDNGBC, and BUILDNGBD. In most
cases, only two of these connections are online: A and B at the initiator site; C and D at the
target site. A and B are used to write to the target site, and C and D receive write requests from
the initiator site. Thus, initiator A writes to target C and initiator B writes to target D.
