What would be the volume flags when a partially written tape (Not marked as full) expires ?

I have many recycle tapes which are marked 'readonly' ,How I will make them not readonly and recycleable(volume flag E) ?

I noticed this problem only on partially written volumes and I am yet to check if more volumes are getting flags r and E as they recycle .

automatically.

Setting the tape to '!readnly' make it 'non recyclable'(Undef) and setting it to recyclable change the volume back to readonly again. I see esg54359 whcih documents it as expected behavior.

slot  volume                                    pool     barcode  volume id        recyclable
    136: AB142(R)                             Default   AB142   2755970564    

Thanks
