This topic describes DFSMSdfp diagnosis information for DFSMStvs.

Any problem from a module that has a name beginning with "IGW8" or any reason code that starts with "6Fxxxxxx" is from DFSMStvs recoverable file services, and any module that has a name beginning with "IGW9" or any reason code that starts with "70xxxxxx" is from the DFSMStvs logger. The DFSMStvs log records include the subsystem ID, like IGWTVS01 and IGWTVS02. Also, any IGW8xx and IGW10xxx messages are from DFSMStvs.

Dumping all the servers in case of a hang applies to DFSMStvs as well as to RLS. Recoverable resource services (RRS) or the system logger can also cause apparent hangs in DFSMStvs or batch jobs that use it, so you might want to dump RRS and the system logger too if you think you have a hang related to DFSMStvs. They might not all fit into one dump, and partial dumps are generally useless, so this might require more than one dump. If you think you have a hung batch job, be sure to dump both the SMSVSAM server and the hung job.
