/dev/rmt/0? mt rew? What is my tape device?
Posted on 2003-02-27
I have a DDS-3 tape device hooked up on my Sun server (Enterprise 450). I thought the device was installed as: /dev/rmt/0 but I ran a command:
mt -f /dev/rmt/0 rew
To see if it would rewind the tape, and nothing seems to happen. No lights come on...and no error message...I just get back to the prompt.
# tar tvf /dev/rmt/0
tar: tape read error
Again...no activity on the tape drive trying to list the contents.
I also ran:
# ufsrestore i /dev/rmt/0
Media read error: I/O error
Trying to get into interactive mode...
Anway...how do I determine the device is installed as /dev/rmt/0? Any troubleshooting help would be appreciated.
