4 Direct target attachment Direct target attachment FCP targets can directly connect to an AG module instead of through a fabric connection, as illustrated in Figure 14.

Considerations for direct target attachment Consider the following points for direct target attachment: • Direct target attachment to AG is only supported if the AG module is also connected to a core fabric. A switch module running in AG mode does not provide Name Services on its own, and routing to the target devices must be established by the core fabric. • Hosts and targets cannot be mapped to the same N_Port. • Redundant configurations should be maintained so that when hosts and targets fail over or fail back, they do not get mapped to a single N_Port. 74 Access Gateway Administrator's Guide 53-1002743-01
