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 >
