I don't know whether you can actually observe the drive, but I'm guessing this drive has a gravity-fed autoloader that pops the next tape into the drive when the previous one has been ejected. If so, you need to wait longer between ejecting the tape and trying to write to the next one -- 40 seconds isn't really enough for the 3490 to rewind, eject, and load the next tape.
Try increasing the delay between operations to 120-150 seconds. That usually works for us. > [EMAIL PROTECTED]:~$cat next.sh > #!/bin/sh > /bin/mt -f /dev/tape/0768/char/nonrewinding rewoff > sleep 40 > exit 0 > ---------------------------------------------------------------------- For LINUX-390 subscribe / signoff / archive access instructions, send email to [EMAIL PROTECTED] with the message: INFO LINUX-390 or visit http://www.marist.edu/htbin/wlvindex?LINUX-390
