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 that has different
requirements to AMF.
In the extremely unlikely situation of needing to replace an entire VCStack that is a
member of an AMF network, you can use AMF automatic node recovery to first recover
Stack ID 1, which will become the VCStack master.
The replacement device which will become the VCStack master must be a clean unit (see
“Restoring a Node to a “Clean” State” on page 145).
The procedure for recovering an entire stack is as follows:
1. Connect a clean device to the AMF network, and power it on. The connections into the
AMF network should be between the appropriately configured AMF links on the
neighboring node, and the ports previously configured as AMF links in the backup for
the failed node configuration.
2. The AMF network should detect the replacement device and begin automatic node
recovery. Wait until automatic node recovery completes, then check that the
replacement device has come up correctly as VCStack ID 1, and that the configuration
is correct.
3. Configure the next replacement device as VCStack ID 2. Ensure it is installed with a
compatible release and the same set of licenses that exist on ID 1. Connect the VCStack
cables and power it on.
4. VCStack ID 1 should detect ID 2 and synchronize the configuration and firmware
release. Once this has completed, check that the VCStack has formed correctly, and
then connect the remaining network connections.
For any additional VCStack members, repeat the last two steps, ensuring that the VCStack
ID is set to the next sequential value for each additional device that is added to the
VCStack.
