CA Disk uses an assortment of records stored in a receptacle, called the FILES, to record information related to the various functions you are executing. The information stored is divided up into sections called subfiles. The following is a list of each subfile and a description of its function:
An index of all data sets in the archives.
An index of tape or disk volumes that contain archived data sets.
Volser names of tapes (assigned to pools) that can be used during archive or backup runs.
A queue for user requests to archive or backup specific data sets.
A queue for user requests to restore specific data sets.
Re-archive grace periods for restored data sets.
DASD space billing records.
Re-catalog information for sequential migration backup tapes.
TSO dynamic (immediate) restore information.
RACF profile name cross-reference.
The next two steps are required for all new users of CA Disk. If you already have an FDS from an 8.1 release or above, you can continue to use that FDS; however, you can create and initialize a new FDS for testing purposes before you install this release into your production environment. If you have a FDS from an 8.0D release or below, see Files Data Set Conversion. If you are using Files Database(FDS), the next two steps can be skipped.
