Managing the failover and failback policies

4. Enter the ag --mapshow command with the n_portnumber operand to display a list of

mapped F_Ports. Verify that the F_Ports you added appear in the list.

switch:admin> ag --mapshow 13

N_Port : 13

Failover(1=enabled/0=disabled) : 1

Failback(1=enabled/0=disabled) : 1

Current F_Ports : None

Configured F_Ports : 6;7

REMOVING F_PORTS

Removing an F_Port from an N_Port unassigns the F_Port. The F_Port status changes to Disabled

(No mapping for F-Port).

To remove an F_Port from an N_Port

1. Connect and log in to the switch.

2. Enter the ag

--mapdel command with the <n_portnumber> “<f_port1;f_port2;...>” operands

to remove the list of F_Ports from the N_Port.

switch:admin> ag --mapdel 13 “5;6”

F-Port to N-Port mapping has been updated successfully

3. Enter the ag --mapshow command with the n_portnumber operand to display a list of

mapped F_Ports. Verify that the F_Ports you removed are not in the list.

switch:admin> ag --mapshow 13

N_Port : 13

Failover(1=enabled/0=disabled) : 1

Failback(1=enabled/0=disabled) : 1

Current F_Ports : None

Configured F_Ports : 7

Managing the failover and failback policies

The failover and failback policies determine the behavior of the F_Port if the N_Port they are

mapped to goes OFFLINE or is disabled. By default, the failover and failback policies are enabled.

This section explains how to change the policy settings.

Both the failover and failback processes are disruptive. When a host connection fails over and fails

back to another online N_Port, the F_Port connection is disabled and then re-enabled on the new

N_Port. Each time the host changes N_Ports, it receives a new PID. The host must establish a new

session to the fabric

CAUTION

If the failback policy is enabled and autofailback occurs, this will interrupt traffic because the ports

need to relogin to their original mapped port thus causing a disruption in traffic.
