The Solution Rating System

With so many solutions, how can you tell which solutions are most likely to help you and which ones are not? To provide you with a tool to use, we rate our solutions based on various elements that most accurately determine if a solution is a quality solution. To explain what factors affect the solution rating, here are the elements we take into consideration when formulating our solution rating.

  • The Grade of the Solution
  • The Zone Rank of the Expert Providing the Solution
  • The Number of Author and Expert Comments
  • The Number of Experts Contributing
  • The Feedback of the Community

Your Input Matters
Because of the way the system is set up, the most important variable in this equation is you. As a member of Experts Exchange, you are able to cast your vote on the quality of the solutions in regard to how complete, accurate, helpful and easy to understand each solution is. When you provide your feedback, each rating is adjusted accordingly. So, if you see a solution that has a poor rating that you think is a good solution, let us know by rating it. As you do, the rating will be adjusted and will become more accurate for other members of our site.

If you have any suggestions that you would like to make for our rating system, please ask a question in the Suggestions Zone of Community Support.

Thank you!

add a tape drive

Asked by zekker in Linux

Tags: ioctl, inappropriate, device, tape

Hello...  I recently got a used DSS tape unit.  However I cannot seem to connect up to it.

Here is some info :

from dmesg
 
(scsi0) <Adaptec AHA-294X Ultra SCSI host adapter> found at PCI 0/16/0
(scsi0) Wide Channel, SCSI ID=7, 16/255 SCBs
(scsi0) Cables present (Int-50 NO, Int-68 YES, Ext-68 YES)
(scsi0) Downloading sequencer code... 436 instructions downloaded
scsi0 : Adaptec AHA274x/284x/294x (EISA/VLB/PCI-Fast SCSI) 5.2.4/5.2.0
       <Adaptec AHA-294X Ultra SCSI host adapter>
  Vendor: COMPAQPC  Model: DDRS-39130W       Rev: S95E
  Type:   Direct-Access                      ANSI SCSI revision: 02




If i run a utility called cdrecord -scan    
you can see that it does see it on the scsi bus..

[root@nis dev]# cdrecord -scanbus
Cdrecord 1.10 (i686-pc-linux-gnu) Copyright (C) 1995-2001 Jörg Schilling

Here is alisting from my /dev directory regarding what I would assubme to be a rmt device.

ls -l | grep rmt
-rw-r--r--    1 root     root        40960 Apr 10 10:44 rmt0
crw-rw----    1 root     disk      12,   8 Aug 30  2001 rmt16
crw-rw----    1 root     disk      12,   6 Aug 30  2001 rmt8

As you can see I do have an rmt0 ! however...  If i do:

mt -f /dev/rmt0 status
/dev/rmt0: Inappropriate ioctl for device


My question:  does anyone know how to get this to respond? If i can get it to even say "hi im here use me"  :)   I would be more than happy!  I am pretty good at linux but kind of new to this portion of it, my expertise is more on the security side of it.  I just would like to do some backups.

Does anyone have any links? or tips? Help!
