I/O errors on the IMS Monitor log data set

If a permanent I/O error occurs on the IMS Monitor log data set, IMS stops the IMS Monitor and issues message DFS2202. In this situation, you cannot restart the IMS Monitor until you restart IMS because IMS does not close the IMS Monitor log data set until you shut down IMS.

If the problem that caused the error has not been corrected when you restart IMS, you should specify a different volume or unit for the new execution.
