Setup Guide

For details on configuring D_Ports, using D_Ports, and D_Port limitations and considerations, refer to the Fabric OS Administrator's
Guide . For details on D_Port-related commands, refer to the Fabric OS Command Reference .
Saving port mappings
Before configuring static D_Ports, you must remove all mappings between the ports and devices because mappings are not retained on
D_Ports. This includes port (N_Port-to-F_Port), device (WWN), static, and dynamic mapping. You can use Fabric OS commands to save
N_Port mappings and to delete saved N_Port mappings. When you disable the D_Ports, use the saved mapping information to assist
manual reconfiguration of the deleted port mappings. Refer to the Fabric OS Command Reference for more details on the backup
mapping commands.
Save port mappings
The following steps show how to save configured N_port mappings.
1. Use the ag --backupmappingsave command with the N_Port variable. The following example saves mappings on N_port 44.
switch:admin>ag --backupmappingsave 44
Display port mappings
The following steps show how to display saved N_port mappings.
1. Use the ag --backupmappingshow command with the N_Port variable to display saved N_Port mappings. You can use the
displayed information to reconfigure the ports. The following example displays mappings on N_port 44.
switch:admin>ag --backupmappingshow 44

Backed-up Static F_Ports 23:24
Backed-up Preferred F_Ports 26:27:28:29
Delete port mappings
The following steps show how to delete configured N_Port mappings.
1. Use the ag --backupmappingdel command with the
N_Port variable to delete configured N_Port mappings. The following
example deletes mappings on N_port 44.
switch:admin>ag --backupmappingdel 44
Limitations and considerations
Consider the following limits and conditions when using D_Ports in AG device configurations:
∙ Any D_Port must be configured on the AG device, fabric switch, or HBA before enabling D_Ports on both sides of the link.
Otherwise, the port will be persistently disabled.
∙ After configuring a D_Port for an AG device port, mapping is not 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.
