Bug ID: 909111 Summary: The rescan-scsi-bus.sh from the sgutils package is broken since SuSE-13.1 Classification: openSUSE Product: openSUSE Distribution Version: 13.2 Hardware: x86-64 OS: openSUSE 13.2 Status: NEW Severity: Normal Priority: P5 - None Component: Other Assignee: bnc-team-screening@forge.provo.novell.com Reporter: dmarkh@cfl.rr.com QA Contact: qa-bugs@suse.de Found By: --- Blocker: ---

This script no longer "finds new" or "removes no longer attached" scsi devices. As shown below, I have a scsi disk at scsi ID-0 at /dev/sg5.

I remove the drive at scsi ID-0 drive and install an additional drive at scsi ID-1 then run the script.

It not only did not remove the one at ID-0 that was removed, but did not find the new one attached. Below is an "lsscsi -g" after a reboot with BOTH drives attached.

Reproducible: Always
Steps to Reproduce: 1. See details 2. 3. Actual Results: This script, before SuSE-13.1 would remove any disks physically removed and add any physically added since boot. It is broken
This is NOT kernel related as the same thing happens with a vanilla 3.16.7 kernel. I'm fairly certain this is a systemd issue.

I removed the SONY tape drive on bus 11 at /dev/st0 , /dev/sg9 and added another SEAGATE SCSI disk at SCSI ID 1 on bus 11.

--- Comment #30 from Mark Hounschell dmarkh@cfl.rr.com --- This bug still exists even though the original BUG report was back in 2015. The last rescan-scsi-bus.sh that actually worked was from the 12.3 dist. I have had to keep the version for 12.3 on my system every since because I use it constantly. Please fix this BUG. I would be happy to attach the 12.3 version of this script but find no way to do it but inline here.

--- Comment #35 from Mark Hounschell dmarkh@cfl.rr.com --- Let me go back and verify which version actually broke it. I went from 12.3 to 13.2. I never used 13.1.

--- Comment #36 from Mark Hounschell dmarkh@cfl.rr.com --- The rescan-scsi-bus.sh from the 13.1 dist also works. It breaks at 13.2. I just now verified this.

--- Comment #38 from Mark Hounschell dmarkh@cfl.rr.com --- Just an FYI, I am running these scripts on 15.3. I have plenty of SCSI devices to play with so anything you want me to try, I can.

--- Comment #41 from Mark Hounschell dmarkh@cfl.rr.com --- Ah, the "-a" flag seems to do the trick. Do you still want the "sh -x" log file?
http://bugzilla.opensuse.org/show_bug.cgi?id=909111 http://bugzilla.opensuse.org/show_bug.cgi?id=909111#c43
--- Comment #43 from Mark Hounschell dmarkh@cfl.rr.com --- Yes, I have verified that the rescan script in 15.3 works with the "-a" flag as far as discovering newly added devices.
This script originally discovered new and removed devices with no "-flags". It appears now that in order for it to work as it did originally you must pass not only the "-a" but the "-r" flag also. The "-r" flag removes removed devices from the list displayed by the "lsscsi -g" command.
Yes, you can close this bug now. Thank you.
