Figure 1 shows the syntax for the USAGE keyword.

ALL

Includes all data sets in the analysis.

ACTIVE (ACTV)

Includes only active data sets. Accessed as read or as write and read, these data sets are not HSM, TEMP, BACKUP, SINGLE, or BCOPY.

BACKUP (BKUP)

Includes data sets that have been opened and processed for output only and are not HSM, TEMP, SINGLE, BCOPY, or ACTIVE. Unlike active data sets, these data sets are probably being placed on tape for backup purposes.

BCOPY (BCOP)

Includes only data sets that have been opened once for input and once for output and are not HSM, TEMP, BACKUP, ACTIVE, or SINGLE. These data sets are likely a specialized form of backup. Perhaps a backup is taken and then re-copied to be sent to a vault.

TEMP

Includes only temporary data sets. Data sets are flagged in GFTAXTR as temporary if they match the system-assigned naming convention for temporary data sets or if they have been allocated as DISP=(NEW,DELETE).

SINGLE (SING)

Includes data sets that have only been accessed on a single day and are not HSM, TEMP, BCOPY, BACKUP, or ACTIVE.

HSM

Includes only those data sets owned and managed by DFSMShsm, such as the migration level 2 and backup single-file format (SFF) data sets and autodumps. GFTAVMA has built-in knowledge of every naming convention that DFSMShsm uses.

NONHSM

Includes all data sets except those that fall into the HSM category.
