[CentOS] Replacement tape drive configuration
CentOS 4.8 Hi All: We recently had a Sony SDX-500V tape drive fail on one of our servers running CentOS 4.8. I have now replaced it with a spare SDX-500C. The problem that I am having now is that the failed drive had ceased responding to SCSI commands and we have since rebooted the system which resulted in the tape drive being removed from our current hardware configuration and the system does not recognize the new tape drive. I know that I can just reboot the system and kudzu will add the tape drive back in during the boot process however I was wondering if it would be possible to manually run kudzu to add the drive or am I just borrowing trouble by trying to do this? TIA Regards, Hugh -- Hugh E Cruickshank, Forward Software, www.forward-software.com ___ CentOS mailing list CentOS@centos.org http://lists.centos.org/mailman/listinfo/centos

TIA Regards, Hugh When you say the 'system' no longer recognizes the tape drive, are you sure the SCSI controller even detects the tape drive during boot? From what I've seen, tape drives use the generic tape driver and get mapped to /dev/stX. Ryan Manikowski ___ CentOS mailing list CentOS@centos.org http://lists.centos.org/mailman/listinfo/centos

From what I've seen, tape drives use the generic tape driver and get mapped to /dev/stX. I know that it will recognize it on a reboot however I did not want to wait until a reboot was convenient. I was looking for a way to add the drive without having to do a reboot. Brian's suggestion has worked and I am now using the tape drive without having to do a reboot.
