Summary
Attempting to open a tape library that is attached to a storage system using the syncui ndmpopen command fails with rc=3019, even though you provide correct values for <jbox_name>, <jbox_ctlid>, <hostname>, <port>, <username>, and <password>. To resolve this issue, ensure that the storage system is in text authentication mode.
Symptoms
The ssjuker log displays the attempt to open the tape library using syncui ndmpopen and the subsequent failure:

Resolution
Important: Although the images in this article depict a specific version of the DPX management console, their functionality is applicable to all currently supported versions.
The storage system is configured with MD5 authentication as follows and displayed in the image below:
NDMPFILER> options ndmpd.authtype challenge
Syncui attempts only text authentication: NDMP_AUTH_TEXT. The DPX management console first attempts to open the tape library with MD5 authentication. If unsuccessful, it uses text authentication.
To open a tape library that is attached to a storage system with syncui ndmpopen, ensure that the storage system is in text authentication mode: options ndmpd.authtype plaintext,challenge.
