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.
# lsscsi -g [0:0:0:0] disk ATA ST3320620AS K /dev/sda /dev/sg0 [13:0:0:0] process Marvell 91xx Config 1.01 - /dev/sg1 [16:0:0:0] disk IMPRIMIS 94601-15 4614 /dev/sdd /dev/sg5 [17:0:0:0] cd/dvd LITE-ON DVDRW LH-20A1P KL0G /dev/sr0 /dev/sg2 [18:0:0:0] disk ATA ST3160811AS E /dev/sdb /dev/sg3 [18:0:1:0] disk ATA ST3160815AS B /dev/sdc /dev/sg4
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.
