Why does the migration process cause a (large) delay for my backups (mediawait) ? I don't understand why backup can't continue while TSM is migrating the data from disk to tape ? There is still enough place in the diskpool !
Can anybody give me any hints are recommandations ? Thank you in advance !! Wouter V.
