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
