I had that problem with over 100 media
I finally found the fix for this.  


Step 1
Check if the media exists in the database

"C:\Program Files\VERITAS\NetBackup\bin\admincmd\nbemmcmd" -listmedia
-mediaid A00001

Step 2
If not add it to the database

"C:\Program Files\VERITAS\NetBackup\bin\bptm" -makedbentry -m A00001
-den hcart -poolnum 1

Step 3
Expire the media

"C:\Program Files\VERITAS\NetBackup\bin\admincmd\bpexpdate" -d 0 -force
-m A00001

Subject: [Veritas-bu] deassign "Netbackup Media" ?

I've got a short stack of 5 media with no images on them that will not
revert to the scratch pool / expire.  When I try to vmquery
-deassignbyid I get the following:

De-assign media by ID is not allowed for NetBackup media.
invalid media ID (8)
 
These media are not in the "netbackup" pool or is this error assuming
they are catalog backup tapes? (They are not.)
 
Here's the vmquery
 
media ID:              IT0284
media type:            1/2" cartridge tape 3 (24)
barcode:               IT0284L3
media description:     ---
volume pool:           Offsite-58 (5)
robot type:            NONE - Not Robotic (0)
volume group:          ---
vault name:            ---
vault sent date:       ---
vault return date:     ---
vault slot:            ---
vault session id:      ---
vault container id:    -
created:               1/26/2007 2:42:58 PM
assigned:              7/18/2007 5:15:10 PM
last mounted:          7/18/2007 5:15:58 PM
first mount:           1/30/2007 4:53:04 AM
expiration date:       ---
number of mounts:      6
max mounts allowed:    ---
status:                0x0
 
Ideas?
 
Someone mentioned a Netbackup Database consitency check tool?  Do I need
to open a ticket and request that?

You're also just changing a reference in the imageDB.  Once your
image/tape cleanup runs, the images will be removed and the tapes will
be moved to scratch if they are now empty and actually came from
scratch.

        You are changing the retention based on the policy.  You may
have backups

        You may also want to ensure that the tapes "came" from the
scratch pool. 
        They may be showing as not assigned in a pool other than
scratch.

        Hello
        
        I have a policy with name Users. I now want to change retention
to all tapes
        in this policy from 2, to 1 year. (I have a custom retention for
2 years as
        retention level 6)
        
        I used the command: 
        bpexpdate -policy Users -recalculate -ret 8
        
        Then I get a warning:
        Are you SURE you want to recalculate expiration dates on all
images that
        meet the following criteria:
        policy       Users
        retention will be changed to 8(1 year) 
        
        Continue?(y/n)
        
        I answers Yes, and the system seems to process for some minutes.
        
        After this I check if this have moved tapes to Scratch, but no.
Beacuse this
        should have realeased a lot of tapes, and moved it to scratch
pool. 
        
        Is it something I missing here? Do I have to manually change
retention on
        every tape?
