DLT device files

Robin King — Wed, 25 Jul 2001 09:13:31 GMT

One of our v-class machines has 8 DLT devices attached to it, however an ioscan shows over twenty devices. I have tried an rmsf to remove the device files and recreated them using insf -C stape -e. However it just creates the same amount of files again.

Any ideas as to what to try next?

Thanks

Rob

Hi,

It is normal to have more than one device file for a tape drive : the OS creates device files for "no rewind" Best compression etc. Check the MAN page of insf for more info.

Sorry didn't make myself clear, what I meant was an ioscan shows 20 of so devices, I didn't mean individual device files, as in no-rewind.

Robin,

Are the DLTs directly connected to the V or attached to a SAN ?

You may have a scsi id conflict.
Check the scsi id's of the tape drives.
You may want to try removing the drives and adding them one at a time to help narrow down the culprit.
