https://bugzilla.kernel.org/show_bug.cgi?id=16463 Summary: aic7xxx: fails to notice if a disk is unplugged Product: SCSI Drivers Version: 2.5 Kernel Version: 2.6.32-24-generic Platform: All OS/Version: Linux Tree: Mainline Status: NEW Severity: normal Priority: P1 Component: Other AssignedTo: scsi_drivers-other@xxxxxxxxxxxxxxxxxxxx ReportedBy: rercola@xxxxxxxxxxx Regression: No I have an external 7-disk array of SCA disks, connected to a backplane, with a disk module that speaks 40-pin Fast SCSI: [ 15.992335] scsi0 : Adaptec AIC7XXX EISA/VLB/PCI SCSI HBA DRIVER, Rev 7.0 [ 15.992336] <Adaptec 2940 SCSI adapter> [ 15.992337] aic7870: Single Channel A, SCSI Id=7, 16/253 SCBs I was testing my RAID-6 setup on these, so I yanked one of them while they were in an MD. dmesg didn't report any change in disk status, and while any IO to the disk stalled in state D forever, Linux never noticed the disk was gone. I tried using the convenient script I keep around for forcing rescans of SCSI and its related friends, which can be found at http://bash.cyberciti.biz/diskadmin/rescan-linux-scsi-bus/, but even after running that, the controller still didn't notice the disk was missing. -- Configure bugmail: https://bugzilla.kernel.org/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are watching the assignee of the bug. -- 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
