Solaris : Tape device names and control the tape drive

Posted on in Categories News last updated March 22, 2005

Before backing up data on a device, you must understand the tape device-naming schema:

First tape device name: /dev/rmt/0
Second tape device name: /dev/rmt/1

rmt = raw magnetic tape device

You can also add special character letter to specify density using following format
/dev/rmt/ZX

Where

  • Z is tape drive number such as 0,1..n
  • X can be any one of following (as supported by your device, read the manual of your tape device & controller to see if all of them supported or not):
  • l – Low density
  • m – Medium density
  • h – High density
  • u – Ultra density
  • c – Compressed density
  • n – No rewinding

For example to specify the first, drive with high-density with no rewinding use device /dev/rmt/0hn.
