How to expand a VSX_cluster on Crossbeam X series chassisN/A
A customer wants to expand a VSX cluster from 1 to 2 members on each Crossbeam X-Series chassis to process more traffic.
During the original design, the system was not configured to have spare IP addresses for either VSX cluster management or for VSX Checkpoint cluster sync IP addresses between the chassis.
From a technical consideration the systems are not required to use contiguous IP addresses across chassis however the IP address contiguity is enforced within a chassis for a given VAP group due to the increment-per-vap command.
For Cluster management, the IP addresses may be from different subnets across the chassis.
For Cluster sync, the IP addresses across the chassis must be within the same subnet.
This procedure should be performed during a maintenance window and the customer should understand that there are potential risks associated with the migration of firewalls in a production environment.
The following procedure explains how to migrate a VSX cluster member from one chassis to another.
