Hi all, I'm having a minor issue with the disk ordering using an LSI 9211-8i (mpt2sas) controller. If i go into the controllers SAS config utility during boot I can identify the disks in the slots. disk 0 -> slot 0, disk 1 -> slot 1, etc.. everyhting is fine. When I boot into debian linux lenny (using the latest backports 2.6.32-31 kernel, this kernel has version 02.100.03.00 of the mpt2sas driver) The disks are ordered this way: /dev/sda = internal SSD connected to the MB /dev/sdb = slot 0 /dev/sdc = slot 1 /dev/sdd = slot 2 /dev/sde = slot 3 /dev/sdf = slot 7 (!) /dev/sdg = slot 4 /dev/sdh = slot 5 /dev/sdi = slot 6 So it seems the first 4 disks connected to SAS port 1 are ordered correctly and the last 4 disks are not. When I check /dev/disk/by-path i see the following: lrwxrwxrwx 1 root root 9 2011-05-13 10:52 pci-0000:04:00.0-sas- 0x500605b001d161b0:1:0-0x4433221103000000:0 -> ../../sdb lrwxrwxrwx 1 root root 9 2011-05-13 10:52 pci-0000:04:00.0-sas-0x500605b001d161b0:1:1-0x4433221102000000:0 -> ../../sdc lrwxrwxrwx 1 root root 9 2011-05-13 10:52 pci-0000:04:00.0-sas-0x500605b001d161b0:1:2-0x4433221101000000:0 -> ../../sdd lrwxrwxrwx 1 root root 9 2011-05-13 10:52 pci-0000:04:00.0-sas-0x500605b001d161b0:1:3-0x4433221100000000:0 -> ../../sde lrwxrwxrwx 1 root root 9 2011-05-13 10:52 pci-0000:04:00.0-sas-0x500605b001d161b0:1:4-0x4433221104000000:0 -> ../../sdf lrwxrwxrwx 1 root root 9 2011-05-13 10:52 pci-0000:04:00.0-sas-0x500605b001d161b0:1:5-0x4433221107000000:0 -> ../../sdg lrwxrwxrwx 1 root root 9 2011-05-13 10:52 pci-0000:04:00.0-sas-0x500605b001d161b0:1:6-0x4433221106000000:0 -> ../../sdh lrwxrwxrwx 1 root root 9 2011-05-13 10:52 pci-0000:04:00.0-sas-0x500605b001d161b0:1:7-0x4433221105000000:0 -> ../../sdi This LOOKS as it should but right now it is not really correct because 1:7 indicates that it should be physical slot 7 (sdi is in slot 6 and not in slot 7) When i use the sas2ircu command line util to LOCATE the disks and I use 1:7 to locate, slot 7 lights up (NOT disk sdi) Is this behavior fixed in a newer version of the driver, and if so what is the corresponding patch to fix this?
