The MKD command was issued to create a new PDS. The SITE DCBDSN parameter was in effect, specifying that all newly allocated data sets should use the data set dcbdsn_name as a model data set for the data set characteristics. The volume containing data set dcbdsn_name was not currently mounted to the system, and when the FTP server attempted to get the volume mounted, an error occurred and the volume was unable to be mounted. The FTP server was therefore unable to determine the data set characteristics for the new PDS.
The MKD command is rejected. Control is returned to the client connection for further command processing.
Either contact the system programmer for the server system to get the volume containing dcbdsn_name mounted (note, the LIST dcbdsn_name command will display the volume that contains dcbdsn_name), or issue the SITE command to change the model DCB data set specified by the DCBDSN parameter, or use the other SITE parameters to specify the data set characteristics without using a model DCB, then reissue the MKD command.
Determine why the volume containing dcbdsn_name cannot be mounted to the system and correct the problem.
