Configuring additional F_Ports
4
The prefset command sets the preferred N_Port for one or more F_Ports. Preferred mapping is
optional. Preferred F_Port to N_Port Mapping provides an alternate N_Port for F_Ports to come
online for predictable failover and failback. An F_Port must have primary N_Port mapping before a
secondary N_Port can be configured. The list of F_Ports to mapped must be enclosed in quotation
marks. Port numbers must be separated by a semicolon.
You delete these same F_Ports using the prefdel command, for example:
--prefdel "F_Port [;F_Port2;...]" N_Port
The prefdel command deletes the preferred N_Port for the specified F_Port(s). The list of F_Ports to
delete from the secondary mapping must be enclosed in quotation marks. Port numbers must be
separated by a semicolon.
To add a Preferred Secondary F_Ports 3 and 9 to N_Port 4
1. Connect and log in to the switch.
2. Enter the ag
--
prefset command with the
<F_Port1;F_Port2; ...> <N_Port>
operands to add
the Preferred Secondary F_Ports to the specified N_Port.
switch:admin>
ag --prefset "3;9" 4
Preferred N_Port is set successfully for the F_Port[s]
To remove the Preferred Secondary F_Ports 3 and 9 from N_Port 4
1. Connect and log in to the switch.
2. Enter the ag
--
prefdel command with the
<F_Port1;F_Port2; ...> <N_Port>
operands to delete
the preferred F_Port mapping from the specified N_Port.
switch:admin>
ag --prefdel "3;9" 4
Preferred N_Port is deleted successfully for the F_Port[s]
Configuring additional F_Ports
By default, on embedded switches, only the internal ports of Brocade Access Gateway are
configured as F_Ports. All external ports are configured (locked) as N_Ports. For more information
on which ports are mapped by default, refer to
Appendix A, “Default Port Mapping”
. The internal
ports connect hosts in the bladed server and external ports connect to the fabric.
To connect an additional FCP initiator to an external port and reconfigure an N_Port as an F_Port
1. Remap any F_Ports on the N_Port being converted. See
“Adding F_Ports”
on page 28.
2. Unlock the N_Port mode to change the port type to an F_Port. See
“Unlocking N_Port mode”
on page 31.
3. Map the newly configured F_Port to an N_Port. See
“Adding F_Ports”
on page 28.
4. Connect the HBA, host, or other FCP initiator to the F_Port.
NOTE
A switch in Access Gateway mode must have at least one port configured as an N_Port.
Therefore, the maximum number of F_Ports that can be mapped to an N_Port is the number of
ports on the switch minus one.
