You can invoke the DFSMSrmm IPCS verb exit routine by using the IPCS VERBEXIT subcommand to obtain diagnostic information. The DFSMSrmm verb exit routine dumps or interprets most DFSMSrmm control blocks including VSAM and buffer-related information. Full DFSMSrmm diagnostic information is available only when an SVC dump includes the DFSMSrmm address space. If the dump does not include the DFSMSrmm address space, the DFSMSrmm verb exit routine interprets only limited information.
