Direct target attachment

FCP targets can directly connect to an AG module instead of through a fabric connection, as

illustrated in Figure 13.

FIGURE 13 Direct target attachment to switch operating in AG mode

Although target devices can be connected directly to AG ports, it is recommend that the switch

operating in AG mode be connected to the core fabric.

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.

• Hosts and targets should be in separate port groups.

• Direct target attachment configurations are not enforced.
