DFSMSrmm considerations when client/server support is enabled

This topic describes utilities that provide restricted functions when run on a client or server system.

DFSMSrmm Utility	Considerations	Where to Find More Information
EDGUTIL	When you run EDGUTIL on a client system, the utility can only process a DFSMSrmm control data set that is not in use by DFSMSrmm. Because there is no control data set for a client system, you cannot run with the active control data set. However, you could recover a backup copy of the DFSMSrmm control data set to the client system to run VERIFY(VOLCAT), VERIFY(SMSTAPE), and MEND(SMSTAPE). When you run EDGUTIL on a server system, you cannot access the TCDB or library for tape libraries that you can only access from the client system. When you run EDGUTIL on a client system and do not specify the MASTER DD, DFSMSrmm issues message EDG6101E and the utility ends with return code 12.	Using EDGUTIL for tasks such as creating and verifying the control data set
EDGBKUP	You cannot process an active DFSMSrmm control data set on a client system. All functions are available on a client system as long as you provide the DD statements for the control data set and journal. This enables you to use the BACKUP and RESTORE options independent of the DFSMSrmm subsystem. When you run EDGBKUP on a client system and do not specify the MASTER DD or JOURNAL DD, DFSMSrmm issues message EDG6101E and the utility ends with return code 12.	Backing up the control data set
