Sample File-Size Distribution Report (Filesize) - HP BACKCOPY Reference Manual

the results in the space allocation consistency-analysis portion of the summary report. To perform
this check, DSAP must be able to copy the disk directory when it is not changing.
If the EXTENTCHECK option is not specified, then directory changes occur during the copy
attempt, DSAP continues the summary report without checking the extent consistency and issues
this message:
Free space changed during directory copy.
Space allocations are too frequent.
Extent check cannot be performed.
If you specify EXTENTCHECK, DSAP tries to copy the directory three times and issues these
messages:
Free space changed during directory copy.
Retrying.
If DSAP cannot copy the directory in three attempts without the directory changing, it terminates,
issues these messages, and does not complete the summary report:
Free space changed during directory copy.
Space allocations are too frequent.
Extent check cannot be performed.
DSAP is being terminated.
If the disk you are checking is exceptionally busy (for example, $SYSTEM), try to perform
EXTENTCHECK when the disk is less active.
FILESIZE
generates the file-size distribution report, an analysis of the distribution of file sizes. See
Figure 16: Sample File-Size Distribution Report (FILESIZE) (page
FILESPACE
generates the file extent-size distribution report, an analysis of the distribution of allocated
extent sizes. The presence of a virtual volume causes all percentages that compare space use
with the size of the disk to be displayed as 0.0 percent. See
Distribution Report (FILESPACE) (page
FREESPACE
generates the free-space distribution report, an analysis of the distribution of free-space extent
sizes. This option is ignored on a virtual volume. It also causes all percentages that compare
space use with the size of the disk to be displayed as 0.0 percent. See
Free-Space Distribution Report (page
LICENSED
causes the DETAIL report to include all of the licensed files in the file set.
NEWFORMAT (G-series only)
causes the DETAIL report to display in the new format that supports 36 GB disks. You must use
this option to run DSAP on any disk larger than 18 GB.
OPENED { [ OVER ] number | UNDER number }
OVER number causes the DETAIL report to include all of the files in the file set whose most
recent open date occurred number days or more ago.
UNDER number causes the DETAIL report to include all of the files in the file set that were
opened in the last number days.
number is an integer in the range 0 through 32,767.
PARTITIONED
causes the DETAIL report to include all of the partitioned files in the file set. DSAP does not
support the PARTITIONED option for SQL/MX format objects.
