https://bugzilla.kernel.org/show_bug.cgi?id=204769 Bug ID: 204769 Summary: SCSI devices missing for disks attached to controller Product: SCSI Drivers Version: 2.5 Kernel Version: 5.12.11 Hardware: Intel OS: Linux Tree: Mainline Status: NEW Severity: normal Priority: P1 Component: AACRAID Assignee: scsi_drivers-aacraid@xxxxxxxxxxxxxxxxxxxx Reporter: linux@xxxxxxxxxxx Regression: No We use an Adaptec ASR8405 RAID controller with LSI backplane. The RAID controller is configured to expose attached disks to the system ("Expose RAW"). Up to Linux 5.1.12, devices would show as expected. lsscsi -v reports: > [0:0:0:0] disk ASR8405 storage V1.0 /dev/sda > dir: /sys/bus/scsi/devices/0:0:0:0 > [/sys/devices/pci0000:60/0000:60:03.1/0000:61:00.0/host0/target0:0:0/0:0:0:0] > [0:1:4:0] disk ATA HGST HUH721212AL T3D0 - > dir: /sys/bus/scsi/devices/0:1:4:0 > [/sys/devices/pci0000:60/0000:60:03.1/0000:61:00.0/host0/target0:1:4/0:1:4:0] > [0:1:5:0] disk ATA HGST HUH721212AL T3D0 - > dir: /sys/bus/scsi/devices/0:1:5:0 > [/sys/devices/pci0000:60/0000:60:03.1/0000:61:00.0/host0/target0:1:5/0:1:5:0] > [0:1:6:0] disk ATA HGST HUH721212AL T3D0 - > dir: /sys/bus/scsi/devices/0:1:6:0 > [/sys/devices/pci0000:60/0000:60:03.1/0000:61:00.0/host0/target0:1:6/0:1:6:0] > [0:1:7:0] disk ATA HGST HUH721212AL T3D0 - > dir: /sys/bus/scsi/devices/0:1:7:0 > [/sys/devices/pci0000:60/0000:60:03.1/0000:61:00.0/host0/target0:1:7/0:1:7:0] > [0:1:8:0] disk ATA HGST HUH721212AL T3D0 - > dir: /sys/bus/scsi/devices/0:1:8:0 > [/sys/devices/pci0000:60/0000:60:03.1/0000:61:00.0/host0/target0:1:8/0:1:8:0] > [0:1:9:0] disk ATA HGST HUH721212AL T3D0 - > dir: /sys/bus/scsi/devices/0:1:9:0 > [/sys/devices/pci0000:60/0000:60:03.1/0000:61:00.0/host0/target0:1:9/0:1:9:0] > [0:1:10:0] disk ATA HGST HUH721212AL T3D0 - > dir: /sys/bus/scsi/devices/0:1:10:0 > [/sys/devices/pci0000:60/0000:60:03.1/0000:61:00.0/host0/target0:1:10/0:1:10:0] > [0:1:11:0] disk ATA HGST HUH721212AL T3D0 - > dir: /sys/bus/scsi/devices/0:1:11:0 > [/sys/devices/pci0000:60/0000:60:03.1/0000:61:00.0/host0/target0:1:11/0:1:11:0] > [0:1:12:0] disk ATA HGST HUH721212AL T3D0 - > dir: /sys/bus/scsi/devices/0:1:12:0 > [/sys/devices/pci0000:60/0000:60:03.1/0000:61:00.0/host0/target0:1:12/0:1:12:0] > [0:1:13:0] disk ATA HGST HUH721212AL T3D0 - > dir: /sys/bus/scsi/devices/0:1:13:0 > [/sys/devices/pci0000:60/0000:60:03.1/0000:61:00.0/host0/target0:1:13/0:1:13:0] > [0:3:0:0] enclosu LSI SAS3x36 0601 - > dir: /sys/bus/scsi/devices/0:3:0:0 > [/sys/devices/pci0000:60/0000:60:03.1/0000:61:00.0/host0/target0:3:0/0:3:0:0] > [N:0:4:1] dsk/nvm Samsung SSD 970 PRO 1TB__1 /dev/nvme0n1 > dir: /sys/class/nvme/nvme0/nvme0n1 > [/sys/devices/pci0000:10/0000:10:01.3/0000:13:00.0/nvme/nvme0/nvme0n1] > [N:1:4:1] dsk/nvm Samsung SSD 970 PRO 1TB__1 /dev/nvme1n1 > dir: /sys/class/nvme/nvme1/nvme1n1 > [/sys/devices/pci0000:10/0000:10:01.4/0000:14:00.0/nvme/nvme1/nvme1n1] On Linux 5.12.11, the devices are missing. lsscsi -v reports: > [0:0:0:0] disk ASR8405 storage V1.0 /dev/sda > dir: /sys/bus/scsi/devices/0:0:0:0 > [/sys/devices/pci0000:60/0000:60:03.1/0000:61:00.0/host0/target0:0:0/0:0:0:0] > [0:3:0:0] enclosu LSI SAS3x36 0601 - > dir: /sys/bus/scsi/devices/0:3:0:0 > [/sys/devices/pci0000:60/0000:60:03.1/0000:61:00.0/host0/target0:3:0/0:3:0:0] > [N:1:4:1] dsk/nvm Samsung SSD 970 PRO 1TB__1 /dev/nvme1n1 > dir: /sys/class/nvme/nvme0/nvme1n1 > [/sys/devices/pci0000:10/0000:10:01.3/0000:13:00.0/nvme/nvme0/nvme1n1] > [N:0:4:1] dsk/nvm Samsung SSD 970 PRO 1TB__1 /dev/nvme0n1 > dir: /sys/class/nvme/nvme1/nvme0n1 > [/sys/devices/pci0000:10/0000:10:01.4/0000:14:00.0/nvme/nvme1/nvme0n1] Output in dmesg is basically the same, except that the following lines are missing with the newer kernel: > [ 17.016661] scsi 0:1:4:0: Direct-Access ATA HGST HUH721212AL T3D0 > PQ: 1 ANSI: 6 > [ 17.018313] scsi 0:1:5:0: Direct-Access ATA HGST HUH721212AL T3D0 > PQ: 1 ANSI: 6 > [ 17.020129] scsi 0:1:6:0: Direct-Access ATA HGST HUH721212AL T3D0 > PQ: 1 ANSI: 6 > [ 17.022530] scsi 0:1:7:0: Direct-Access ATA HGST HUH721212AL T3D0 > PQ: 1 ANSI: 6 > [ 17.024291] scsi 0:1:8:0: Direct-Access ATA HGST HUH721212AL T3D0 > PQ: 1 ANSI: 6 > [ 17.026041] scsi 0:1:9:0: Direct-Access ATA HGST HUH721212AL T3D0 > PQ: 1 ANSI: 6 > [ 17.027725] scsi 0:1:10:0: Direct-Access ATA HGST HUH721212AL > T3D0 PQ: 1 ANSI: 6 > [ 17.029395] scsi 0:1:11:0: Direct-Access ATA HGST HUH721212AL > T3D0 PQ: 1 ANSI: 6 > [ 17.031145] scsi 0:1:12:0: Direct-Access ATA HGST HUH721212AL > T3D0 PQ: 1 ANSI: 6 > [ 17.032672] scsi 0:1:13:0: Direct-Access ATA HGST HUH721212AL > T3D0 PQ: 1 ANSI: 6 The only change on the system to obtain the different behavior is upgrade/downgrade of the kernel via kexec. -- You are receiving this mail because: You are watching the assignee of the bug.
