Using EDGINERS

You can use EDGINERS in either automatic processing mode and manual processing mode. Initialize and erase actions that are defined in the control data set drive automatic processing. With automatic processing, volumes are initialized and erased without operator intervention. SYSIN within JCL or operator commands drive manual processing. You might set up a job that initializes new volumes using automatic processing to minimize librarian intervention. Use manual processing for initializing volumes when you want to change a known, existing volume serial number to another volume serial number. Scan can be performed in manual mode only.

For volumes already defined to DFSMSrmm, the initialize and erase processing is dependent on the action being set for the volume. You can only erase volumes that have the ERASE release action pending, and you can only initialize volumes that have the INIT release action pending. These are some important things to remember:

You can set the INIT action for any volume at any time, but be careful not to do this for the wrong volume.
- To set the INIT action, issue this command: RMM CV volser INIT(Y)
To set the INIT release action pending, set the INIT release action first and then when the volume is released, the INIT action is set pending.
- To set the INIT release action pending, issue this command: RMM CV volser RELEASEACTION(INIT)
To set the ERASE release action pending, set the ERASE release action first and then when the volume is released, the ERASE action is set pending.
- To set the ERASE release action pending, issue these two commands:
  - RMM CV volser RELEASEACTION(ERASE)
  - RMM CV volser RELEASE
- Be careful when you use this way to force the ERASE action. Once the volume is erased, there is no way to recover the data.

DFSMSrmm also provides these automated ways to set the ERASE release action:

By the SECCLS parmlib option. When data sets are created, DFSMSrmm automatically sets the ERASE action for the volume based on the SECCLS parmlib option. See Defining security classes: SECCLS for additional information about the SECCLS parmlib option.
By the RACF 'erase on scratch' attributes from the DATASET class profiles. This way is only available to you when the DEVSUPxx parmlib option TAPEAUTHDSN=YES is in use. When data sets are created, DFSMSrmm automatically sets the ERASE action for the volume based on the DATASET profile 'erase on scratch' attribute.

EDGINERS supports a TAPE DD which might have been allocated dynamically using the S99TIOEX, S99ACUCB, and S99DSABA options of dynamic allocation.
