Restarting the DFSMSrmm subsystem

If you changed the DFSMSrmm running mode as described in Changing the DFSMSrmm running mode and need to activate the DFSMSrmm subsystem interface to implement the change, use the operator MODIFY command shown in Figure 1:

Figure 1. Restarting the DFSMSrmm subsystem

F DFRMM,M=xx

where:

M=xx: Specifies the suffix of parmlib member EDGRMMxx.

The subsystem temporarily stops and reinitializes itself with the new OPMODE. Use this command whenever you update DFSMSrmm parameters and want to implement the change.

During this restart, DFSMSrmm issues the message shown in Figure 2, unless you have IPLed the system since adding EDGSSSI to IEFSSNxx in SYS1.PARMLIB, in which case the interface is already initialized.

Figure 2. Message EDG0103D

EDG0103D DFSMSrmm SUBSYSTEM INTERFACE IS INACTIVE -
              ENTER "IGNORE", "CANCEL" OR "RETRY"

Reply RETRY to this message. In response, DFSMSrmm initializes its subsystem interface. If you reply IGNORE, the DFSMSrmm tape recording function is not activated.
