DFS271 UNABLE TO LOAD ERROR MESSAGE OUTPUT DESCRIPTION

Explanation
 The system was unable to load the error message output
description.

System action
 Block fetch has failed for the IMS default message output description or the
associated device output format. Fetch also failed for a requested
message output description or a device output format. The LTERM was
marked inoperable with a QERROR status, and the message causing the
problem was returned to the message queue. This message is sent to
the z/OS® system console if
the LTERM involved is the master terminal.

Operator response
(master terminal)  Notify your IMS system programmer. The MTO should
ensure that the IMS default message output
description and device output formats are in the format library and
that I/O errors are not occurring. If use of the LTERM is to continue,
a /START LTERM xxx command must be issued. The
message can be removed from the message queue with the /DEQUEUE command. 

Programmer response
 See the description of message DFS057I
for possible causes of block fetch errors.

Problem determination
 Log record type X'67', subrecord X'01',
ID'FERR' which contains diagnostic information, is produced automatically.
