A storage control session is suspended whenever a system reset is issued to the storage control with an active session. This message is a warning that a suspended session exists that cannot be properly recovered. See z/OS DFSMS Advanced Copy Services for procedures to determine which sessions are currently suspended and how to recover those sessions. Failure of those actions to correct the problem indicates that the storage control session is permanently suspended until the storage control is re-IMLed.

This is probably a hardware error. Before reporting the problem, search the problem reporting databases for a solution. If no solution exists, contact the IBM® Support Center. Provide the system log and associated SYS1.LOGREC information.
