Disconnecting and Reconnecting HA
You can disconnect the two devices in the HA system and return them to standalone devices.
|
➢
|
To disconnect HA through CLI: |
|
1.
|
From the CLI of the active device, connect (Telnet) to the redundant device, by typing the following command: |
# debug ha conn-to-red
|
2.
|
Log in to the redundant device's CLI with its username (e.g., Admin) and password: |
Username: Admin
Password:
|
3.
|
Access the Privileged mode, by typing the following command, and the mode's password: |
> enable
Password:
#
|
4.
|
At the prompt, type the following command and enter a new OAMP IP address for the redundant device: |
# debug ha disconnect-system <New OAMP Address for Redundant Device>
The redundant device restarts, the HA status of the active device changes to "Standalone", and the redundant device now becomes a non-HA device.
|
●
|
The new OAMP address of the redundant device must be different to the active device. |
|
●
|
The HA Maintenance network interface (in the IP Interfaces table) on the redundant device is unaffected by the command. |
|
●
|
All Media + Control network interfaces (in the IP Interfaces table) on the redundant device are deleted. |
|
●
|
The 'HA Remote Address' [HARemoteAddr] field value, which specifies the HA Maintenance address of the active device is deleted on the redundant device. |
You can later restore the HA system, by following the below procedure.
|
➢
|
To restore the HA system through CLI: |
|
1.
|
On the previously redundant device, configure the HA Maintenance interface address of the active device: |
(config-network)# high-availability
(ha)# remote-address <HA Maintenance Address of Active Device>
The HA Maintenance address can alternatively be configured in the Redundant device's Web interface's 'HA Remote Address' parameter.
|
2.
|
Restart the redundant device: |
(ha)# do reload now
The procedure assumes that no network changes were made to both devices' HA Maintenance interface or Ethernet Devices (VLAN); otherwise, the devices may not be able to communicate with each other.
