HPDP requests a tape that not exists

Hello together,

our HP DP 9.03 request this tape
 Mount request for medium:
        MediumId        : fe81fde5:53847f36:0550:0002
        Label           : 503331L5
        Location        :
        Device          : xxx
        Host            : xxx
        Slot            : 27

in slot 27 it is a tabe with the label 503331L5 but with the medium id d41ea8c0:562a10bc:400c:0007
Now i want set the protection of    MediumId        : fe81fde5:53847f36:0550:0002 to  permanent.
Or can you tell me to thay HPDP to use an other medium if one medium will not be found, because there are 40 Tapes in freepool, so enouth to use.

Thanks
and Sorry if this issue is post in an other threat, but on every serarc i have found about 50 pages of results....
