D__Port must be configured on the AG, fabric switch, cascaded AG switch, or HBA before enabling
D_Ports on both sides of the link. Otherwise, the port will be persistently disabled.
After configuring D_Port for an AG switch port, mapping will be not be retained. Static D_Port
configuration cannot be made unless mappings are removed from the port. This includes F_Port-to-
N_Port, static, preferred, and device (WWN) mapping. Therefore, all mappings must be manually
removed on the Access Gateway port before configuring the port as a D_Port.
Saving port mappings
Before configuring static D_Ports, you must remove all mappings between the subject ports and
devices as they will not be retained. This includes port (N_Port-to-F_Port), device (WWN), static, and
dynamic mapping. You can save N_Port mappings using Fabric OS commands. Once you save the
mappings, you can display them so that you can manually reconfigure them after the D_Port is
disabled. A command is also available to delete saved N_Port mappings. The following are available
backup mapping commands. For more details, refer to the Fabric OS Command Reference .
To save configured N_Port mappings, enter the following command:
ag --backupmappingsave N_Port
To display saved N__Port mappings so that you can reconfigure them on the switch, enter the
following command:
ag --backupmappingshow N_Port
Following is an example of command output:
sw0:root>ag --backupmappingshow 44
