Why we are unable to take backup on tape device ?

Solution Unverified - Updated -


  • Tape backup is not happening.
  • Receiving DR_OPEN IM_REP_EN when checking for the  tape device status, what does that indicate ?
  • RedHat is not able to communicate with LTO tape drive. I've already rebooted the server but nothing. Moreover nothing appears in messages file when I disconnect the tape and reconnect it.
[root@server ~]# mt status
/dev/tape: No such file or directory
  • Do I need any driver?
