Accidently assigned to redhat-config-services. What's the /proc/version for the kernel under test? 2.4.18-14 Please add the modprobe for the host adapter into /etc/rc.modules. Sometimes hotplug won't lift scsi HBAs, and I don't remember how RHL 8 handled it. Let me know if that resolves the problem. EOL'd. |
Description of problem: I have a VXA-2 Exabyte Tape drive and a Iomega USB CDROM drive. The SCSI card is Adaptec. The tape drive is internal and thus always connected to the SCSI card. If I boot with the CDROM plugged in then /proc/scsi/scsi has only the CDROM and no tape drive even though the tape was detected on boot. If I do an mt -f /dev/st0 status then the tape drive is not recognized (no such device). I issued the scsi add-single-device command but the /proc/scsi/scsi file was unchanged. I issued the scsi remove-single-device command and the CDROM was removed, but I still had no luck with the add-single-device for the tape drive. If, however, I boot with the CDROM unplugged, then the /proc/scsi/scsi file comes up empty. If I issue the mt status command right away then the tape drive is enabled, associated with /dev/st0 and added to the /proc/scsi/scsi file. I can even plug in the CDROM drive after that and it too will be enabled and added to the /proc/scsi/scsi file. If I do things in this specific order then I can have both devices. Version-Release number of selected component (if applicable): How reproducible: 100% reproducible Steps to Reproduce: 1. plug in CDROM 2. boot 3. cat /proc/scsi/scsi and note CDROM only 4. mt -f /dev/st0 status and get error 5. echo 'scsi add-single-device 0 0 11 0'>/proc/scsi/scsi and notice that the drive is not added 6. unplugg CDROM and reboot 7. cat /proc/scsi/scsi and not that the file does not exist 8. issue mt -f /dev/st0 and note the enabling messages and the association of the drive to /dev/st0. 9. cat /proc/scsi/scsi and the tape drive is there 10. plug in the CDROM and watch it enable 11. cat /proc/scsi/scsi and not that both the tape drive and CDROM are there Actual results: Tape drive is not recognized when system is booted with USM CDROM plugged in Expected results: Boot should recognize both the CDROM and the tape drive Additional info:
