The following parameters are used with TMSCLEAN:
This parameter marks expired tapes available for use, and produces a file containing a list of all scratched data sets with a starting volser and file sequence number. Although a tape volume has expired, the volume cannot be used for output until it has gone through scratch processing. This listing identifies the volume serial numbers of tapes that have moved into scratch status since TMSCLEAN was last executed. Tapes are bypassed from SCRATCHLIST for the following reasons:
Virtual WORM tapes are processed and get their WORM information cleared when they are scratched.
This parameter produces a report file of all active tapes in scratch status, regardless of how long the volumes have been in scratch status. No additional scratching of volumes is performed with SCRATCHRELIST.
This parameter extends the expiration date for tapes that are due to expire on a specific date or within a range of days, such as during company holidays or vacation shutdowns.
This parameter scans the TMC and turns off the scratch bit for any volumes that have an expiration date in the future. If an invalid date was used to IPL the system, and TMSCLEAN was executed with the SCRATCHLIST parameter, the invalid date could cause the scratch bit to be turned on prematurely. The data sets are not re-cataloged to the system catalogs.
This parameter updates TMC volume and DSNB records that are marked as expired by Catalog Control. This parameter is used if TMSCTLG expired data sets due to missing system catalog information.
This parameter suppresses updating of the TMC but the appropriate reports are still generated. The TEST parameter can be used with any of the options that are listed previously. When specified, TEST must be the first entry in the parameter field.
