An administrator is trying to troubleshoot the environment after NCC raised an alert: Detailed information for remote_site_connectivity_check: Node…

The NCC alert indicates connectivity failure to the remote site. Resolving this involves confirming

network connectivity and re-establishing the remote site configuration if necessary.

From the Nutanix Enterprise Cloud Administration (ECA) course materials:

“The primary ports used for replication between clusters are 2009 (for Prism Element API) and 2020

(for data replication). Ensuring these ports are open and reachable is critical for remote site

connectivity.”

Also:

“If the remote site has been re-imaged or reconfigured, it may have a new cluster incarnation ID. In

such cases, the remote site configuration must be recreated to align with the current cluster

information.”

Steps like checking ping with MTU 9000 (D) are not directly related to remote site connectivity for

replication, and NAT configurations (B) are generally not recommended unless explicitly required.
