I have a small 7.4 test environment (Solaris 10 server) that includes an
AFT device with a stage policy 70/50% (hi/low) that writes to a standalone
SDLT320 drive for staging. I've seen more that once where there's plenty
of space on the tape (this morning it's only 27% used), but the AFT is
100% full and staging is stalled.
daemon.log shows :

ad infinitum...
Yet, there's space on the stage pool target tape. No tape errors, etc.,
etc.
Why doesn't it stage? In the past I've had to label a new tape into the
stage pool, then it would continue. However, both times there's been free
space on the existing tape and in both cases the very same tape had
previously been successfully staged to (as is the case here).
Any ideas? Not that I'm going to let it bother me over the holidays, but I
need to answer this nonetheless... :-)
Thanks.
