The columns in the Statistical Mount Savings Breakdown are:
- DATA SET CATEGORY:
- The tape mount management data set categories. See Categories of Tape Mount Management Data Sets for a description of these categories.
- CURR STAT MOUNTS:
- The current number of statistical mounts for each tape mount
management data set category. See Statistical Mounts.
- TARG STAT MOUNTS:
- The number of statistical mounts that would still occur for
each tape mount management category if tape mount management was implemented
according to the various parameters specified
in the GFTAVMA run.
- DFSMS - PRIMARY CURR MNT#:
- The number of mounts that occurred because the corresponding
data sets are residing on DFSMS primary storage.
- DFSMS - PRIMARY TARG MNT#:
- This field is always blank because these values are always zero.
The PRIMARY TARG MNT# value is reduced to zero because the data sets
that caused these mounts would still be residing on primary DASD in
the simulated environment.
- HSM - LEVEL 1 CURR MNT#:
- The number of mounts that occurred because the corresponding
data sets are residing on DFSMShsm migration level 1 storage.
- HSM - LEVEL 1 TARG MNT#:
- This field is always blank because no physical tape mounts are
required to recall a data set that is compacted on migration level
1 DASD.
- HSM - LEVEL 2 CURR MNT#:
- The number of mounts that occurred because the corresponding
data sets are residing on DFSMShsm migration level 2 storage.
- HSM - LEVEL 2 TARG MNT#:
- Number of mounts that would be incurred by DFSMShsm migration
level 2 in the target environment.
- TAPE DIRECT CURR MNT#:
- Number of current mounts that fall into the Tape Direct Category
(for example, data sets larger than the LARGE keyword value).
- TAPE DIRECT TARG MNT#:
- Number of mounts for the LARGE data sets in the target
environment using
the type of tape hardware specified by the TAPEDEV and TAPELEN keywords.
