Direct target attachment
FCP targets can directly connect to an AG module instead of through a fabric connection, as
illustrated in
Figure 14 .
FIGURE 14 Direct target attachment to switch operating in AG mode
Although target devices can be connected directly to AG ports, it is recommended 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.
