Tape Drive (/dev/rct0) donot work sometimes
Hi all,
I am facing problem with my Tape drive (hp) (/dev/rct0) on SCO Unix version 6.0.0. Sometimes tar works fine but some times it doesnot work and I have to restart the server to get it work. One reboot/shutdown is OK. to solve the problem. Error is "cannot open /dev/rct0" though the tape is recognised (ls /dev/rct0 is there). Same tape drive is Ok at one time and other time this problem is there.
Powering ON/OFF tape device is of no help
This is not the issue of tapes
Only rebooting the box fixes the problem.
I am not getting what exactly is the problem.
Help is appreciated,
regards,
Dexter

Hey folks,
Linux admin here, forced to use Opensolaris to try to use ufsdump/ufsrestore to get some data of some old tapes.
I've got Opensolaris 2009.06 on x86 and a Sony SDX-700V.
As a "control" experiment, I booted the system with a Linux live CD and the tape drive worked perfectly.
