Step 19: Starting DFSMSrmm

Set the OPMODE operand in parmlib member EDGRMMxx to M to start DFSMSrmm in manual mode. Tape mounts are processed as they were before you began implementing DFSMSrmm. Refer to Defining system options: OPTION for information about setting OPMODE. See z/OS DFSMSrmm Managing and Using Removable Media for information about operator procedures.

Then, issue the z/OS START command to start the DFSMSrmm subsystem, as shown in Figure 1:

Figure 1. Starting DFSMSrmm

 S DFRMM,M=xx,SUB=jesp

where:

DFRMM: Specifies the procedure name.
M=xx: Specifies your chosen parmlib member name suffix.
SUB=jesp: This is an optional keyword to identify the name of the job entry subsystem. DFSMSrmm must not run under the MSTR subsystem. If the DFSMSrmm procedure name you use matches the subsystem name in IEFSSNxx as described in Updating IEFSSNxx, you must specify the SUB keyword when starting the DFSMSrmm procedure. The value jesp is the procedure name of your job entry subsystem and can be specified as SUB=JES3 or SUB=JES2.

If your DFSMSrmm procedure has a PARMLIB DD statement with DDNAME=IEFRDER, there are several other parameters that you can specify with the START command. You can specify keyword parameters that are supported on a DD statement. For example, you can specify DSN= to override the control data set name on the IEFRDER statement, as shown in Figure 2:

Figure 2. Starting DFSMSrmm with additional parameters

S DFRMM.name,M=xx,DSN=parmlib_name

where:

name: Specifies a name other than DFRMM by which you can call the DFRMM procedure. You can then use this name on STOP and MODIFY commands.
M=xx: Specifies a specific parmlib member with which DFSMSrmm should be started instead of the default parmlib member.
DSN=parmlib_name: Specifies an alternative data set name to be used as a parameter for this restart of the DFSMSrmm subsystem.

DFSMSrmm is now running in manual mode.
