Sorry, I caught these out of order.  It looks like you are using a VXA 
drive.  In another post someone said that Exabyte states that it can 
take up to 20 minutes for a VXA drive to load a tape.  I have personally 
experienced around 10 minute loads  This is what I did to fix my load 
problems on Ubuntu with a VXA drive.

To fix the ubuntu problem

Change  the case function in mtx-changer to (this should be in v2.4.1):

OS=`uname`
case ${OS} in
  SunOS)
    ready="No Additional Sense"
    ;;
  FreeBSD)
    ready="Current Driver State: at rest."
    ;;
  Linux)
    ready="ONLINE"
    if test -f /etc/debian_version ; then
       mt --version|grep "mt-st" >/dev/null 2>&1
       if test $? -eq 1 ; then
      ready="drive status"
       fi
    fi
  ;;
esac

To fix the vxa load time edit wait_for_drive to increase its timeout:

wait_for_drive() {
  i=0
  while [ $i -le 300 ]; do  # Wait max 25 minutes
    if mt -f $1 status 2>&1 | grep "${ready}" >/dev/null 2>&1; then
      break
    fi
    debug "Device $1 - not ready, retrying...in 5 seconds"
    sleep 5
    i=`expr $i + 5`
  done
}

In your sd.conf add the following to your tape Device:

Maximum Changer Wait = 1800 #30 minutes
