CISCO ESA de-commission queries

[sachin garg]

Issue:- Question on Decommission C390 ESA.

Queries:-

1. Since the EOL appliances are part of the cluster (together with the Production appliances), do we need to detach it before proceeding with the decommission process? The status of these appliances is suspended (no email flow).
2. Will it impact the other Production appliance if we detach it from the cluster (downtime)?
3. Can you provide the detach guide.

[Ken Stieers]

1. Yes, you should detach it from the cluster so that other members aren't trying to replicate configuration changes to it.
2. No, removing an ESA has no effect on the other ESAs in the cluster
3. Connect to the CLI

Esa> clustermode cluster

(MyCluster)> clusterconfig

Thank you for above details. One last query on this.

Is it possible to provide any URL, where these steps are listed?

In the help on the ESA, look for "Leaving a cluster permanently"
