The z/OS® Media server could be reached during a ZOSMEDIA library request. However, authentication could not be completed. The TSM server will not continue the operation because the z/OS Media server connection can be authenticated.
The operation fails.
Determine why the z/OS Media server connection cannot be authenticated. Check to ensure the PASSPHRASE option on the TSM z/OS Media server matches the serverpassword of the media server definiton on the TSM Server. The password cannot exceed 16 characters.
