  Problems Accessing Tape Device? 
 The Question is:
 
Hello Wizard,
 
I am new to the VAX-OpenVMS OS and am having difficulties performing a backup
 to a Compaq Tape Drive. We are running OpenVMS V5.5-2 on a model 4000-300 VAX
 machine. After shutting down w/ the the REBOOT_CHECK option, I ensure that the
 TAPE Drive is indeed
 ONLINE. When at the $ prompt, I enter the below command for the backup.
 
$backup/image/verify DRIVENAME: mua0:setDATEOFBACKUP.bck/label=none/rewind
 
The system comes back telling me that it can't find the device or the device is
 not mounted and asks if I want to perform another backup. Am I doing something
 wrong? How could I fix this?
 
Any assistance would be greatly appreciated.
 
Thanks,
 
Brian McDonald
 
 
 The Answer is :
 
  Your device configuration is invalid, your tape device unsupported,
  your device faulty, your specified device name is incorrect, or
  OpenVMS device autoconfiguration is disabled.  This can be a result
  of a device-level configuration error, or due to an incorrect CSR
  setting on one or more Q-bus controllers, or any number of other
  potential problems.
 
  The MU device indicates a TMSCP-accessable tape device, such as a
  TU81 series nine-track magtape or the TK50 series cartridge tape
  device.  It also implies you are using Q-bus-based controllers or
  potentially DSSI-based device access, though there are certainly
  other configuration options possible.  (The device name does not
  specifically which of a large number of differing tape devices and
  tape controllers and tape I/O connection technologies are in use.)
 
  Please contact HP customer services for assistance with resolving
  this, as details of the device and the device configuration will
  be required.
