Considerations for performing other operations when ECA is deployed
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.
