The SCAN command is used to tell CA Disk to scan the VTOCs of volumes, or to scan ICF, VSAM or explicitly named OS CVOL catalogs. A SCAN or FIND command must precede any action commands. If any SELECT and/or EXCLUDE commands are used, they must follow the SCAN command(s) and precede the action command(s). If you request a scan of a protected catalog and you desire to supply a password to CA Disk, a PASSWORD command should precede the SCAN CATALOGS= command.
On any given SCAN command, one and only one of the following parameters must be specified:
These parameters tell CA Disk what type of scan is to be performed. With REALVOLS, the volume VTOCs will be scanned, whereas the CATALOGS= parameter will cause ICF, VSAM or explicitly named OS CVOL catalogs to be scanned.
