Adding DLT80e tape drive to NetServer

Gregory Lee — Tue, 24 Jul 2001 06:28:34 GMT

I have installed Linux on an LX Pro Netserver and now I want to attach a DLT80e tape drive to it. What's the correct procedure?

I came across the command to add SCSI devices "on the fly":

echo "scsi add-single-device 5 0 4 0" > /proc/scsi/scsi

But nothing is registered in the /proc/scsi/scsi file which currently has:

Host: scsi0 Channel: 00 Id: 05 Lun: 00
Vendor: TOSHIBA Model: CD-ROM XM-5701TA Rev: 0787
Type: CD-ROM ANSI SCSI revision: 02

Host: scsi2 Channel: 03 Id: 00 Lun: 00
Vendor: MegaRAID Model: LD0 RAID5 20330R Rev: C
Type: Direct-Access ANSI SCSI revision: 02

What should I do next? The other problem I hv is to verify that I got the right host adapter ID, SCSI channel... what's the best procedure to verify all this? Currently I'm just guessing the combination :(

I have already set the SCSI ID to 4 for the tape drive.

Thanks in advance.

What operating system are you using? What ever you will have to do a hardware add for the tape drive. You can only do this after the system has been reboot and can see the drive.

As I recall, the external SCSI port is run from a different controller channel. I think a reboot, with the tape drive turned on, will be needed for the controller to recognize a device on that channel.

Thanks. I did a reboot of the server and it could recognise the tape drive.

Although I gather from the SCSI-HOWTO that you can actually add the device without rebooting the server, hmmmm....

After the reboot:-

Host: scsi1 Channel: 00 Id: 04 Lun: 00
Vendor: QUANTUM Model: DLT8000 Rev: 0114
Type: Sequential-Access ANSI SCSI revision: 02

I can see the DLT tape.

Cheers,
