how to refresh H/W driver in RedHat Linux
 

Hi all

This is a problem with a production box . SCSI tape is sensed properly and it showing claimed . but when ever we r going to take backup it is saying no device found . we can not reboot system for this reasion . please tell me if any one is knowing the proccess to refresh the h/w driver in linux system. and how we can update that driver withot reboot.

Problem is with RHEL-3 servers the on site guys has attached scsi tape drive while running the servers . ls mod is showing the scsi tapes but when I am running cat /proc/scsi/scsi that time it show
Attached devices: none

tell me the command to get the scsi tpae claimed in /proc/scsi/scsi without reboot


sushil:tisk:

Drivers are "kernel modules", and you can load and reload them with command-line utilities, but this is unlikely to be the problem.

Please be aware that "Red Hat Linux" (RHL) has been discontinued and has been out of support for some years, so questions that mention RHL may go unanswered, because these products should not be in production use anymore - you need to specify either "Red Hat Enterprise Linux" or "Fedora Core" if you are using a current version.

rhel as 3
 

The same problem has happened with me in the RHEL 3 AS.

How do I refresh the tape drivers ? will the modprobe help me ? or is there any specific utilities in RHEL 3 that can help me ?
