Re cataloging expired tapes

Question

We have a pair of tapes that we need to recover some files from. Sadly they are outside of our retention range, which was an oversight with setup and I have fixed that. But I mark the tapes as free then unmark them as free and select re catalog tapes. It
worked on one tape and showed how much data is written to tape, the second tape is re catalogs it but does not show how much data is written to tape. The when I go to the recovery tab and select external DPM tapes I cannot drill down at very far at all into
what I need and I am pretty sure the files I need are on the tape that is not showing how much data is written. I have tried running the re catalog again with no luck. Any ideas?

Hi,
You can try this….
1) Make a backup of the DPM database.  (dpmbackup.exe -db)
2) Write protect the tapes, then in DPM right-click and select "Mark tape as Free", then right-click and select "unmark tape as free".
3) Close the DPM Console
4) Open SQL management studio and connect to the DPM Instance.
5) Run the following SQL script to remove external tapes tree under recovery tab.
Use dpmdb  ---change db name accordingly
delete from dbo.tbl_MM_MediaMapWhere DatasetID in (select DatasetId from dbo.tbl_MM_PhysicalDataset where ExternalDatasetInformationId IS NOT NULL)
delete from [DPMDB].[dbo].[tbl_MM_PhysicalDataset]where ExternalDatasetInformationId IS NOT NULL
Delete from dbo.tbl_MM_ExternalDatasetInformation
where dependantdatasetid IS NULL
6) Now try re-cataloging the tapes and see if the recovery point shows up under the new external tapes tree.
