Logging In to the ECS Using CloudShell to Check Migration Management Node Logs

If a migration task is abnormal, you can log in to the ECS of the migration cluster to check the run logs of the migration management node. In this way, you can analyze the cause of the failure according to the error or warning information. This section describes how to log in to an ECS using CloudShell. Obtain the permission to open ports before preceding.
