Software Upgrade
You can perform the following types of software upgrades on the HA system:
■ Software Upgrade with Device Reset: Both active and redundant devices burn and reboot
with the new software version. This method is quick and simple, but it disrupts traffic (i.e.,
traffic affecting).
■ Hitless Software Upgrade: This method maintains service (i.e., not traffic affecting).
For more information, see Software Upgrade.
Disconnecting and Reconnecting HA
You can disconnect the two devices in the HA system and return them to standalone devices.
➢ To disconnect HA:
■ On the active device, enter the following CLI command:
# debug ha disconnect-system < new OAMP address of redundant 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) are deleted on
the redundant device.
● The 'HA Remote Address' (HARemoteAddr) field value, which specifies the HA
Maintenance address of the active device, is deleted on the redundant device.
● The command causes the redundant device to reset.
You can later restore the HA system, by following the below procedure.
➢ To restore the HA system:
1. On the previously redundant device, configure the HA Maintenance interface address of the
active device in the 'HA Remote Address' field, or through CLI:
(config-network)# high-availability
(ha)# remote-address < HA Maintenance address >
