Hello,

Now I really don't understand TSM anymore !

Look at this DR situtation :

   - DB is restored ("after the complete library has been destroyed")
   - Remove definitions of scratch volumes (they aren't in the lib anymore)
   - Remove definitions of cleaning volumes
   - Change access of primary tape pool(s), in my case PTAPE_POOL to destroyed
   - checkin new tapes as scratch volumes
   - Checkin offsite copy
   - double the maxscratch value of ptape_pool (from 5 to 10), all allowed (5)
scratch tapes were used before
   - do a restore stgpool of ptape_pool from offsite_2
   - restore OK
But :

question 1:

  All 5 tapes in accessstate "destroyed" are not known anymore in storagepool
  ptape_pool , but q stg still shows the double capacity ??  Who can explain
  this ?

These are the new volumes : OK

(capacity of destroyed tapes is still included ???)
5 x 200 = 1000, q stg shows 2000 ??
