Thanks Guys. Failover testing was successful this morning and we are back on Hub-A as it was before and Hub-B is acting as Passive;ready We followed the below plan this morning and had a successful outcome 1. Unplug white cable from port3 of both A & B as its not in use and going to rackspace switches and monitor both appliances for a good few minutes 2. Unplug the only Uplink from port1 of LON5-Hub1-B to force the failover to A and wait for a good 5-10 minutes for A to become master 3. If all looks good on A then reconnect the Uplink on LON5-Hub1-B and wait for a good 5-10 minutes for B to join the cluster as Passive;ready 4. Unplug the only Uplink from port1 of LON5-Hub1-A to force the failover to B and wait for a good 5-10 minutes for B to become master 5. If all looks good on B then reconnect the Uplink on LON5-Hub1-A and wait for a good 5-10 minutes for A to join the cluster as Passive;ready 6. Finally flip it back to A by disconnecting the Uplink on B and leave it We cannot answer few questions from our customer though which is a shame 1. What confidence do we have that it won’t happen again? 2. why did it work this time and not last time?
