2 – Parameters
2.1 – root-file-spec
The root file specification of the database for which you want the corrupt or inconsistent storage areas or snapshot files logged to the CPT to be displayed.
3 – Command Qualifiers
3.1 – Options
Options=Normal Options=Full Options=Debug Specifies the type of information you want displayed, as follows: o Normal Displays the active CPT entries and the corrupt or inconsistent areas sorted by area and page. o Full Displays the same information as Normal plus the disks on which the active CPT entries and the corrupt or inconsistent areas or snapshot files are stored-sorted by disk, area, and page. o Debug Provides a dump of the entire CPT and lists all the storage areas. Options=(Normal) is the default qualifier.
3.2 – Output
Output[=file-name] Specifies the name of the file where output is sent. The default is SYS$OUTPUT. The default output file extension is .lis, if you specify only a file name.
4 – Usage Notes
o To use the RMU Show Corrupt_Pages command for a database, you must have the RMU$BACKUP, RMU$RESTORE, or RMU$VERIFY privilege in the root file access control list (ACL) for the database or the OpenVMS SYSPRV or OpenVMS BYPASS privilege. o You can repair and remove a corrupt snapshot file from the CPT by issuing the RMU Repair command with the Initialize=(Snapshots) qualifier. Using the Repair command in this case is faster than performing a restore operation. See Repair for details.
