http://bugzilla.kernel.org/show_bug.cgi?id=11619 Summary: Hotplug doesn't work with SAS1064 Product: IO/Storage Version: 2.5 KernelVersion: 2.6.27-rc6 Platform: All OS/Version: Linux Tree: Mainline Status: NEW Severity: high Priority: P1 Component: SCSI AssignedTo: linux-scsi@xxxxxxxxxxxxxxx ReportedBy: vseliverstov@xxxxxxxxxxxxxx Latest working kernel version: 2.6.20 Earliest failing kernel version: 2.6.22 Hardware Environment: Any Intel-powered server with SAS1064 PCI-X SAS controller Problem Description: I have linux-box with SAS1064 PCI-X SAS Controller, and I'm experiencing problems with hotswapping. When I detach disk from system, replace it with another one, and trying to attach it again, nothing happens. After reboot, it's OK - I have this disk attached and functioning. Interesting, that if I try to attach old disk just after detaching it's OK too. I've tried following Vanilla kernel builds from linux git tree: 2.6.20, 2.6.22, 2.6.24, 2.6.26, 2.6.27-rc6 and it's worked only with 2.6.20. So, I tried to bisect buggy commit between 2.6.20 and 2.6.22 versions. Here is bad commit: df9e062ad994c4db683377b108c0dbed4690e4b0 Steps to reproduce: - detach disk with: # echo "scsi remove-single-device x y z k" > /proc/scsi/scsi - physically remove it and insert another one; - try to attach disk with: # echo "scsi add-single-device x y z k" > /proc/scsi/scsi or with echo "- - -" > /sys/class/scsi_host/hostN/scan -- Configure bugmail: http://bugzilla.kernel.org/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are the assignee for the bug, or are watching the assignee. -- To unsubscribe from this list: send the line "unsubscribe linux-scsi" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
