Added a second drive to our library and added the second drive as a destination target to all existing backup jobs. Load balancing was enabled for all the existing jobs so to avoid writing to two tapes I set the Min/Max to 1:1. Backup tasks do correctly write to only a singe drive BUT it appears to still often grab both drives (status shows Inactive/Waiting for both drives on one job and on another concurrent job one device shows Running and the other Inactive/Waiting)
From reading about Load Balancing this doesn't seem to be correct behavior. Is there another option other than recreating all existing jobs?
