You can delete the save sets from the media database.  

You could: nsrmm -d -y <VOLUMEID> (will remove all the savesets from Networkers 
knowledage and the tape will be marked as not in media index.  Be careful make 
sure you don't want anything on this tape before issueing that command.

Or just label the tape without it being eligible for recycling yet.

If you are only wanting to remove some of the savesets from one tape and hoping 
it that you can write to the same tape without labeling it I don't believe this 
is possible, however I could be wrong.

To delete ssid's manually without re-labeling, I just use 'nsrmm -S "12345678" 
-dy' (where the number is ssid to delete) , and then run 'nsrim -X' to clean 
out the mmdb.. (Is this bad?) - I've never been in the situation where I 
absolutely had to re-label a tape (yet!).. :\
