Degraded mode does not equate to being no tape available.
I forgot to change my six tape cartridge a little while ago.
Yet 5 days of backups collected normally, not degraded, in
my holding disk spaces (plural).
Degraded mode is not able to tape AND insufficient holding
disk space for level 0 dumps. Both conditions must exist.
Now, why aren't you seeing anything in your holding disk?
