DFSMSrmm automatically records some data set details each time a data set is opened or closed. DFSMSrmm puts restrictions on the automatically recorded information that you can change. You can change the security level recorded for a data set without restriction. To change other fields, DFSMSrmm requires that you have access to STGADMIN.EDG security resources. To change the date that the data set was last read or written to, you must have CONTROL access to STGADMIN.EDG.MASTER security resource. To change other data set details that were recorded by DFSMSrmm during O/C/EOV processing, you must have CONTROL access to STGADMIN.EDG.MASTER security resource and UPDATE access to STGADMIN.EDG.FORCE. See CHANGEDATASET: Changing data set information for information on the data set details that you can change.

To change information recorded by DFSMSrmm for a particular data set on a volume you own:

1. Select Option 2 (DATA SET) on the User Menu and press ENTER. DFSMSrmm displays the Data Set Search panel.

   You might also want to tailor the search criteria. For example, if you want a list of only data sets that match a data set name, enter a data set name. Use the Limit field if you want DFSMSrmm to return the specified number of data sets. Otherwise, all the data sets that have met the search criteria are returned.

   Specify a volume serial number and specify Yes for List entire set and DFSMSrmm displays all the data sets in a multivolume set.

   Press ENTER to request a list of data sets on volumes you own. DFSMSrmm returns a list of data sets. Press PF11 to see additional data set information. Find the data set you want to change and type C in the line operator column (S), beside the data set name. Press ENTER.

   DFSMSrmm displays a DFSMSrmm Change Data Set Details panel containing information defined for the data set.

2. Enter information in the DFSMSrmm Change Data Set Details panel to change information. There are some restrictions on the changes you can make. For example, if DFSMSrmm automatically recorded information about the data set when the data set was opened, you can only change the data set's security level, date last read or date last written to.

   Press PF1 or use the HELP command for field-specific help for information on the fields you can change.

3. Press ENTER to request your changes.
