If ECA is deployed and you want to add a new node to the cluster:

• Before starting an add node operation, generate a new certificate request which has the new node's storage server FQDN as an additional SAN entry.

• Do not add the media server FQDN in the SAN entry.

• Upload the new certificate and then add the new node. Otherwise, the add node operation will fail.

If ECA is deployed on a cluster where disaster recovery is configured and you want to add a new node to the cluster:

• The ECA has to be renewed on the primary irrespective of whether you add the new node on the primary or secondary cluster.

• The new certificate must contain FQDN of the storage server of the node which is going to be added.

• A new CSR has to be generated which contains the FQDN of the new storage server as a SAN entry. A new certificate is generated with the new CSR which is used for ECA deployment/renewal.

• Do not add the media server FQDN in the SAN entry.

If ECA is deployed and you want to add a new data network:

• Add the new primary and storage server FQDNs to the CSR and deploy the new certificate before adding the new data network.

• Do not add the media server FQDN in the SAN entry.
