Troubleshooting remote cluster

• Failed to register remote storage cluster on local GUI REST-API.

Failed to register remote storage cluster on local GUI REST-API.

The remote cluster resource is not READY and describing the resource shows the status: Failed to register remote storage cluster on local GUI REST-API. Check the operator logs for more details.

This error might be caused from the inability to resolve the hostname of the contact nodes on the storage cluster from the core pods. Check the operator logs and look for a failure on mmremotecluster add command.

mmremotecluster: Incorrect node node1.example.com specified for command.
mmremotecluster: Command failed. Examine previous error messages to determine cause.

To resolve, double check that you are able to resolve the hostnames of the contact nodes by using nslookup. If you are unable to fix the site DNS, you can also resolve this using hostAliases field in the Cluster spec to add entries into the IBM Storage Scale CoreDNS host file. For more information, see Host aliases.
