Standalone Tapes

Hello Experts,

We are running out of the tapes on one IBM3500 library. Tapes expire on this library on its own and then we reuse it we dont offsite these tapes.

I checked in Standalone and I could see there are many tapes which are in Active MPX as media status and these tapes are showing data expiration

dates past few months. I dont know why.

These are in showing unassinged in IBM3500 library.

So can I use this tapes and expire these as these are showing back dates expiration dates? Is there any issue using these?

Please help.
