1 /BRIEF
Displays summary information for each CFB: CFB address, CVB address, access count, active I/O count, and file specification or ID*. The /BRIEF qualifier is incompatible with each of the /EXTENTS, /FULL, and /STATISTICS qualifiers. *If the file specification is available, via LIB$FID_TO_NAME(), it is displayed; otherwise, the FID is displayed. Note that, because the volume is accessed through its logical name, if two volumes are mounted that have the same logical name (for example, one mounted /SYSTEM and one mounted privately, which results in the same logical name in two different access-mode logical name tables), the incorrect file specification might be displayed.
2 /CLOSED
Displays only CFBs whose access count is zero.
3 /CVB
/CVB=address Displays CFBs whose CVB address matches the specified one.
4 /DISPLAY_NAME
/DISPLAY_NAME (default) /NODISPLAY_NAME Controls whether the file specification is displayed.
5 /EXTENTS
/EXTENTS Displays the cache extents held in cache for any displayed files. This shows the primary and secondary cache extents along with their data state and VBNs. Also shows a summary of memory usage (pagelets used and pagelets valid) for any displayed files. The /EXTENTS qualifier is incompatible with the /BRIEF qualifier.
6 /FULL
Displays all fields for each Cache File Block except for those displayed by the /EXTENTS and the /STATISTICS qualifiers. This is the default. If the file specification is available, via LIB$FID_TO_NAME(), it is displayed; otherwise, the FID is displayed. Note that, because the volume is accessed through its logical name, if two volumes are mounted that have the same logical name (for example, one mounted /SYSTEM and one mounted privately, which results in the same logical name in two different access-mode logical name tables), the incorrect file specification might be displayed.
7 /ID
/ID=file-id Displays only information about files whose file ID match the one specified. The file id (FID) is the hex file number component in a [file number, sequence number, relative volume number]-format file ID.
8 /OPEN
Displays only CFBs whose access count is greater than zero.
9 /STATISTICS
/STATISTICS Displays more statistics about the specified file. The /STATISTICS qualifier is incompatible with the /BRIEF qualifier.
