Tape inventories run against nonexistent tape libraries

Question

I accidentally left my DPM server on while working on the fibre channel zoning to let my DPM server see my tape library; as a result, it sees some bogus tape libraries.  I disabled them in the GUI and they don't show up any more, but DPM still tries
to inventory the library (which I subsequently named "GhostLibraryThatDoesntExist").
Device Manager shows exactly one medium changer and exactly one tape drive.
Here's what PowerShell tells me is there:
PS C:\sys> Get-DPMLibrary -DPMServerName avamarproxy | select-object UserFriendlyName,IsOffline,IsEnabled | Format-List
UserFriendlyName : IBM ULTRIUM-TD4 SCSI Sequential Device
IsOffline        : True
IsEnabled        : True
UserFriendlyName : IBM ULTRIUM-TD4 SCSI Sequential Device-3
IsOffline        : True
IsEnabled        : False
UserFriendlyName : GhostLibraryThatDoesntExist
IsOffline        : True
IsEnabled        : False
UserFriendlyName : IBM ULTRIUM-TD4 SCSI Sequential Device-2
IsOffline        : True
IsEnabled        : True
UserFriendlyName : Adic01
IsOffline        : False
IsEnabled        : True
UserFriendlyName : IBM ULTRIUM-TD4 SCSI Sequential Device-4
IsOffline        : True
IsEnabled        : True
Adic01 is the only valid device of the bunch.
I found a similar forum post with a third-party SQL query solution (http://social.technet.microsoft.com/Forums/en-US/dpmtapebackuprecovery/thread/3a2905f1-eefc-4d29-b5ed-2ddeb7c30100)
and before I run that I'd like to know whether or not this has been fixed in the year since the post was active.
Thanks,
Tom

Hi,
You can use this procedure to disable the bogus library and scheduled tape inventory job.
MAKE A BACKUP OF THE DPMDB BEFORE PROCEEDING:  Run DPMBACKUP -DB
IN THIS EXAMPLE, WE HAVE ONE LIBRARY WITH FIVE TAPE DRIVES.
1) Copy the  "SQL script to modify"  found below into notepad.
2) Open sql management studio.
3) Open The DPMDB and expand the tables.
4) Create a NEW QUERY and execute the following Query:
Select libraryid, GlobalLibraryID from dbo.tbl_MM_Library where isoffline='true'and description = 'TapeLibrary'
It should return a single row:
 LibraryID                              GlobalLibraryID
 139859e0-f6ab-471a-9dad-f9c13c68f22d   0e867b9c-9f23-4317-88b4-6b437fa0e222
In the notepad that has the sample sql script:
- Find, Replace tbl_MM_Library_TAPELIBRARY-ID with LibraryID GUID returned 139859e0-f6ab-471a-9dad-f9c13c68f22d.
- Find, Replace the tbl_MM_Library_GLOBALLIBRARY-ID with the GlobalLibraryID GUID Returned 0e867b9c-9f23-4317-88b4-6b437fa0e222
5)  Run the following QUERY:   Substituting the LibraryID GUID with the LibraryID GUID returned from the above Query.
select Driveid from dbo.tbl_MM_drive where libraryid = '139859e0-f6ab-471a-9dad-f9c13c68f22d'
  DrIveID
  f634984f-9f3b-48af-87af-1f37c516e9f9
  277e2a0e-2c70-432b-b7dc-2e1a5ff3f218
  6148fdba-1a5e-401a-bac1-484934638408
  61c8c1cf-eb07-4635-bcf3-49b7c3d02f43
  8826ef5a-1f1a-4495-a677-50215e0962b6
In the notepad that has the sample sql script:
- Find, replace the dbo.tbl_MM_TapeDrive_DRIVEID-1 with f634984f-9f3b-48af-87af-1f37c516e9f9
- Find, replace the dbo.tbl_MM_TapeDrive_DRIVEID-2 with 277e2a0e-2c70-432b-b7dc-2e1a5ff3f218
- Find, replace the dbo.tbl_MM_TapeDrive_DRIVEID-3 with 6148fdba-1a5e-401a-bac1-484934638408
- Find, replace the dbo.tbl_MM_TapeDrive_DRIVEID-4 with 61c8c1cf-eb07-4635-bcf3-49b7c3d02f43
- Find, replace the dbo.tbl_MM_TapeDrive_DRIVEID-5 with 8826ef5a-1f1a-4495-a677-50215e0962b6
6) In the notepad that has the sample sql script. REMOVE ANY LINES FOR DRIVES THAT ARE NOT USED and also delete the comments  " <<<remove if not used".
IE: In a Single drive library, Remove EXTRA values for the following, and remember to remove the "," in the last entry, other wise you will get error "Incorrect syntax near ',' when the script is executed.
    'dbo.tbl_MM_TapeDrive_DRIVEI-DX'
7) Now copy and paste the resulting script into the query window and execute it.   This should prevent any future inventory jobs from running.
