Jean-Louis,
googled it... I had my numbers wrong, it can supposedly hold
800 Gig, and with HW compression up to 2x that. I should not
have to adjust the tape length and no reason (that I can see)
for dumps to take more than one tape.
Its odd that I'm not seeing an end of media error message...
I think I need to run a cleaning tape and keep an eye on this.
thank you,
Brian
