Operator response
Notify the system programmer, print the SYS1.LOGREC, and request the SVC dump.

Problem determination
If you suspect an error in DB2, you might need to report the problem. For information about identifying and reporting the problem, see Collecting diagnostic data.
The unexpected media manager reason code is saved in register 8.
