Summary of Space Use
For the specified disk, the summary of space use lists the total number of:
• Free pages (available for file allocation)
• Allocated pages (assigned to a file)
• Unused pages (assigned to a file but beyond the current end of file)
• Deallocatable pages (unused pages in assigned but empty extents)
To reclaim deallocatable space, use the FUP DEALLOCATE command to return unused extents.
Exceptional Condition Report
The exceptional condition report consists of:
• Space-allocation consistency analysis indicates the consistency of free space and allocated
space and notes any overlapped extents, lost free space, unspared defective sectors, or free
extents out of order in the free-space table. For information on lost free space and extent
overlaps, see Guidelines: Running DSAP (page 99).
• The summary of space allocation anomalies, which divides the space-allocation consistency
analysis into disk free-space table inconsistencies, doubly allocated pages, and lost free-space
pages.
• The media-failure analysis, which reports if the disk (primary or mirror) is DOWN or has
unspared defective sectors. If the disk has any unspared defective sectors, DSAP displays:
{ Primary } disk has num unspared defective sectors.
{ Mirror }
Please eliminate bad sectors using the
PUP SPARE command.
When DSAP performs a summary analysis for a single user, the summary report is truncated (see
Figure 12). These are examples of commands that produce this report:
1> DSAP $DATA, USER KIN.MARTIN
2> DSAP $DATA, USER 3,85
Figure 12 Sample Summary Report for a Single User
To generate a summary report for a full-volume analysis:
1> DSAP $SYSTEM
