Node recovery
Page 32 | How to Configure and Use AMF on Allied Telesis Switches
When these situations occur, automatic node recovery may fail.
If automatic node recovery fails, the replacement device will have AMF safe configuration
mode applied, (see section "AMF safe configuration" on page 34). If automatic node
recovery fails, you may wish to proceed with manual node recover y, which can be initiated by
entering the command:
atmf recover {<node_name>} {<master_node_name>}
Where:
node_name is the host name of the device you wish to recover.
master_node_name is the host name of the AMF master that contains the backup you
want to use for the recovery.
Here is an example showing manual recovery:
Note: The manual recovery command will bypass the usual checks performed by automatic
node recovery, it is important to be confident that the backup configuration stored on
the specified AMF master is correct prior to executing the command.
If the replacement device is of a different type to the one stored in the backup on the
specified AMF master node, the incompatible release file from the backup will not be copied
to the replacement device. Instead, the existing release on the replacement device will be
used, in order to ensure the device is able to join the AMF network and function correctly.
Node recovery on VCStacks
Node recovery on VCStacks that are part of an AMF network is somewhat different to node
recovery of standalone devices. This is because VCStack has its own node recovery
mechanism which has different requirements to AMF.
Typically a failure on a VCStack will only affect one stack member.
In this instance, so long as:
The replacement device is running a compatible firmware version
The Stack ID on the replacement device is set to the same ID as the device being replaced
The replacement device is installed with the same licences as other stack members
Then, VCStack will synchronize the configuration and firmware.
