external device (eg. ext tape drive) 1

[dbase77]

Hi all,

I have SCSI card installed on our machine but no device attach to it (eg. ext tape drive). I want to attach the ext tape drive now. Do I need to reboot my machine in order to get the device created (touch reconfigure and reboot machine)? Or I can just run this program "devfsadm" from comman line?


Thank you in advance.

regards,

power the machine down and attached the SCSI cable to the cpu and the device. Make sure that the target on the back of the device is set to (4). once you have this done power-up
the tape drive and power-up the cpu.
It should find it during start-up.

The Unix system a target 4 assigned as a tape drive 8mm.

Normally tape drives are ID'es as target 4 or 5. They can be at any unused target address.

You con't have to take the ssytem down.

1. Address the tape drive ( target ID)
2. Connect the cable and drive to the scsi card
3. power on the tape drive.
4. look at /dev/rmt and see what drives are now
configured, if any.

5. run devfsadm -c tape

6. look at /dev/rmt for the new device
7. if seen then load a tape and run this command.

mt -f /dev/rmt/* status (* = drive # as seen in
the /dev/rmt file)

8. end

Without roobting you can configure tape drive.

Install all hardware,

#drvconfig; devlinks; tapes

#cd /dev/rmt

#ls -ltr you will find new device.

Insert a tape into tape drive then type,

#mt -f /dev/rmt/x status
