Marking mode
The default mode for the tool. In marking mode, the tool checks all the caches on the local server for
the presence of the DICOM object files that the database says should be present. For missing files, the
"visible" field in the database osr_location table is set to 'C'. (Normally this field contains the value 'T'
for true, or 'F' for false). Changing this field makes these file locations invisible to the product software.
The reporting tool may be rerun after further recovery work has been completed (more files restored
to cache). In these cases the tool also checks locations with visible value 'C'. If any files have been
restored to cache since the last run of the tool, it sets those locations' visible values back to 'T' to indicate
that they are now valid.
After the missing DICOM object file locations are marked, a report is generated for the studies that
contain lost objects. Each comma-delimited line in the report lists the patient name, patient ID, modality,
accession number, study description, study date, total number of objects, and number of lost objects
for an affected study.
Note:
In the report, any commas in these fields are replaced by a semicolon.
Deregister mode (-r)
In deregister mode, the tool changes the 'C' values to 'F'. This triggers the Autopilot program to
permanently delete these locations from the database. (This is a normal Autopilot function). Please
note that there is no undo.
Note:
Before running the tool in deregister mode, the operator must check the report to ensure that
the losses are as expected. If the report seems to report any files that may not be missing,
the tool operator should follow the instructions given in the TROUBLE section. A copy of the
report and additional diagnostic messages are written to the log file.
Performance of mvf-report-loss is hardware dependent. For comparison, on a standalone Sunfire 280R,
mvf-report-loss scans about 2,000 files per second.
