CBR0028I Error pinning UCB at address address for device device-number. Return code = return-code, Reason code = reason-code.
Explanation
The OAM control task attempts to "pin" the MVS™ Unit Control Block (UCB) at address address for device device-number using the UCBPIN service. The request was unsuccessful. For diagnostic purposes, return-code and reason-code are the return code and reason code, respectively, from the UCBPIN service.
System action
OAM initialization stops.
Operator response
Repeat the OAM start-up procedure. If the failure persists, notify the system programmer.
System programmer response
For information on UCBPIN return codes and reason codes, see z/OS MVS Programming: Authorized Assembler Services Reference SET-WTO. If the problem recurs and if the program is not in error, search problem reporting databases for a fix for the problem. If no fix exists, contact the IBM® Support Center.
