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 !!
