When a shared device class is updated and the number of drives in the associated library is greater than the mount limit of the device class, an attempt is made to delete drives so that there are as many drives as the mount limit. One or more failures occurred in deleting drives. The number of drives does not correspond to the mount limit for the associated device class. This can cause resource balancing problems between the server and storage agents.
The server continues operation.
Use the QUERY DRIVE command to get the names of the drives associated with the library. Use the QUERY DEVCLASS deviceclass F=D command to find the mount limit of the associated device class. Use the DELETE DRIVE command to delete drives until the number of drives in the library corresponds to the device class's mount limit.
