Tape I/O

When the AIX kernel attempts to write to a tape device, is it possible
to read what is being sent over the channel?

Hmm. Well, if it's not, the tape drive's gonna have a hard time doing
its job.

If you're talking about intercepting the outgoing data with a program
on the box, yeah, that's doable. You'd need to be root to pull it off,
though.

Hi. Root access isn't a problem...it's knowing how to intercept,
redirect or read a log of the scsi commands sent to the drive that's
the problem! Any tips on how to see or read this would be gratefully
received. Thanks, Simon.
