Geoff,
I deal primarily with backups directly to tape and have seen this error message
when the number of tapes in the volume is equal to the  Maximum Scratch Volumes
Allowed parameter for that storage group. I increase this value and backups go
on.  It might be helpful to see the storage pool details.
