HP Data Protector 9 : How can i reuse the Tape without recycling?

Hi Everyone,

I have a little issue with my tape even after the all backups in the tape has now been "not protected" but still DP is not going to reuse this tape without recycling. Case is as below:

Status               Backups     Protection         Data Type      Size

Completed      1stbackup    not protected      full                10GB
Completed     2ndbackup   not protected      incr               1GB
Completed     3rdbackup    not protected      incr               1GB
Completed     4thbackup    not protected      incr               1GB
Completed     5thbackup    not protected      incr               1GB

Now the tape has been full but not able to overwrite or reuse. How can i do that without recycling the tape?
