     s3     true    Ready 

     • The Enable column shows whether the S3 service instance is enabled or disabled.
     • The deployment phase of the service instance shown in the Phase column can be one of the following values:
       • Ready: The service instance is ready to be used for S3 account creation or export creation.
       • Configuring: The service instance configuration is in progress.
       • Connecting: The service instance is trying to establish communication between the S3 endpoints and the S3 database.
       • Failed: The service instance configuration has failed.
       Restriction: Once you issue the service creation command, for a brief period of time, the Phase column might be empty.
