Installing external DLTvs80 tape drive in D380

Nagaraja Dyava Setty — Wed, 04 Aug 2004 20:36:08 GMT

I need help in setting up the DLTvs80 tape drive in DL380 server running RedHat Enterprise Edition. It is externally attached using built in SCSI port.

At present i can't see this drive in RedHat Linux. But during POST the drive is detected.

I would assume that it can't be seen with the OS boot-up for one of two reasons.

1) The on-board SCSI drivers aren't being loaded. Once the machine is up, use the 'lsmod' command to ensure teh aic7xxx driver is loaded.

2) The tape modules aren't loaded. Once again, with 'lsmod', ensure the 'st' module is loaded.

Once both are loaded, check what the contents of '/proc/scsi/scsi' report.

Strangely enough, 'cdrecord -scanbus' is also good at picking up tape drives, even if the 'st' module isn't loaded (you just can't use it in that state).

If you have to 'modprobe' to install either of these drivers, use the 'dmesg' command to review the message of found devices etc. after the command. You'll get a better idea of what's going on that way.

I would check that the scsi id of the drive doesn't conflict with the card. Since it shows up on bios, this is not a likely cause.

There are specifc drivers for this tape drive which you may need to install from the manufacturer site.

What bus technology is the DLT8K running?

We have them in both LVD and HVD.

LVD needs to go on the S/E bus, and will
require the correct terminator to make the
drive happy.

HVD will need to go on the D/F bus, and
the controller will need to be set for
external bus operation.
