Space Distribution Reports; Sample Summary Report For An Entire Disk - HP BACKCOPY Reference Manual

Figure 13 Sample Summary Report for an Entire Disk
In the parentheses of the summary of space use are percentages of the total disk pages on the
volume. The allocated pages percentage plus the free pages percentage might not equal 100
percent. The system tables (containing the disk directory, free-space table, spare tracks table,
volume label, and others) use the remaining space.
If DSAP reports that a file has doubly allocated extents (and the message SQL Shadow appears
after the file name), the file is an SQL table that was dropped, but the drop is not yet committed.
The file is invisible, but its extents are still allocated until the drop is committed. If there are no
outstanding drop transactions, use the SQLCI CLEANUP command to remove this entry. For more
information, see the SQL/MP Installation and Management Guide.

Space Distribution Reports

DSAP performs space-distribution analysis for these types of space:
Type of Space
Free-space extents
Allocated file extents
Both free and allocated extents
Entire files
All report types first display the summary report. (See
To produce a free-space distribution report:
1> DSAP $volume FREESPACE
For each extent size, the free-space distribution report displays:
Number of free extents
Total pages (of 2048 bytes each) occupied by the free extents
Total pages (of 2048 bytes each) occupied by the free extents of that size or smaller
Free space used as a percentage of the total free space on the disk
Free space used as a percentage of total disk space
