Failover policy

Deleting a preferred secondary N-Port for device mapping (optional)

Use the following steps to remove a secondary N_Port where devices will connect if their first or
primary N_Port, if defined, is unavailable.

1. Connect to the switch and log in using an account assigned to the admin role.

2. To delete an N_Port configured as a failover port for one or multiple devices mapped to a

specific N_Port, enter the ag --delwwnfailovermapping N_Port command with the
“[WWN];[WWN]” option. All of the listed devices will stop using the N_Port if the first N_Port
mapped to the devices is unavailable unless they log in through F_Ports that are mapped to
the N_Port.

The following example removes N_Port 32 as the secondary N_Port for two devices already
mapped to a primary N_Port.

ag --delwwnfailovermapping 32

“10:00:00:06:2b:0f:71:0c;10:00:00:05:1e:5e:2c:11”

To remove an N_Port as a failover port for all devices mapped to the N_Port, enter the ag
--delwwnfailovermapping N_Port command with the --all option.

The following command removes N_Port 32 as the secondary N_Port for all available devices.

ag --delwwnfailovermapping 32--all

Enabling and disabling the Failover policy on an N_Port

1. Connect to the switch and log in using an account assigned to the admin role.

2. Enter the ag

failovershow N_Port command to display the failover setting.

switch:admin> ag --failovershow 13

Failover on N_Port 13 is not supported

3. Enter the ag

failoverenable N_Port command to enable failover.

switch:admin> ag --failoverenable 13

Failover policy is enabled for port 13

4. Enter the ag

failoverdisable N_Port command to disable failover.

switch:admin> ag --failoverdisable 13

Failover policy is disabled for port 13

Enabling and disabling the Failover policy for a port group

The Failover policy can be enabled on a port group. Use the following steps to enable or disable the
failover on all the N_Ports belonging to the same port group.

1. Connect to the switch and log in using an account assigned to the admin role.

2. Enter the ag

failoverenable -pg pgid command to enable failover.

switch:admin> ag --failoverenable -pg 3

Failover policy is enabled for port group 3
