Managing the failover and failback policies

ENABLING THE FAILOVER POLICY

A switch in Access Gateway mode supports automatic N_Port failover to other N_Ports connected

to the same fabric. When a port is first configured as an N_Port, the failover policy is enabled by

default.

If the N_Port goes offline, the F_Ports mapped to that N_Port are automatically failed over to other

online N_Ports connected to the same fabric. If there are multiple online N_Ports connected to the

same fabric, the mapped F_Ports are distributed evenly between the N_Ports.

Failover generates an error message.

To enable failover

1. Connect and log in to the switch.

2. Enter the ag command with the

--failovershow <n_portnumber> operand to display the

failover setting.

switch:admin> ag --failovershow 13

Failover on N_Port 13 is not supported

3. Enter the ag command with the --failoverenable <n_portnumber> operand to enable failover.

switch:admin> ag --failoverenable 13

Failover policy is enabled for port 13

To disable failover

1. Connect and log in to the switch.

2. Enter the ag command with the

--failovershow <n_portnumber> operand to display the

failover setting.

switch:admin> ag --failovershow 13

Failover on N_Port 13 is supported

3. Enter the ag --failoverdisable command with the --failoverdisable <n_portnumber> operand

to disable failover.

switch:admin> ag --failoverdisable 13

Failover policy is disabled for port 13

ENABLING THE FAILBACK POLICY

A switch in Access Gateway mode supports automatic F_Port failback to N_Ports when that port

comes back online. By default the failback policy is enabled.

When an N_Port with an enabled failback policy comes back online, the F_Ports that were originally

mapped to it are automatically rerouted back to the N_Port.

To enable failback

1. Connect and log in to the switch.

2. Enter the ag

--failbackshow command with the n_portnumber operand to display the failover

setting.

switch:admin> ag --failbackshow 13

Failback on N_Port 13 is not supported

3. Enter the ag --failbackenable command with the n_portnumber operand to enable failover.
