Hello, on a DL385 G2 I needed some JBOD disks and built a SAS controller into the server, because the builtin Compaq P400 controller does not support JBOD. Luckily the 8 x SAS 2.5" drive cage of the server has two SAS connectors on the back, with one addressing the first four SAS disks (A) and the other one disks five to eight (B) So I had the P400 connected to A and the LSI SAS Controller 3442E-R to connector B of the drive cage. The problem now is, that with 7.2 Release the SCSI disks of the LSI SAS controller show up as da0, da1, etc. What I wanted was that disk devices of the ciss controller take precedence over disk devices of the LSI SAS controller (mpt driver) so I have da0 as boot disk on the P400 So I have right now.. mpt0: da0 mpt0: da1 ciss0: da3 ciss0: da4 and not as wanted: ciss0: da0 ciss0: da1 ciss0: da2 mpt0: da3 mpt0: da4 What I already tried: - Putting the 3442E-R into two different PCIe slots What options do I have to get the ciss controlled da0-da3 show up before the mpt devices? Any hint appreciated, Cheers, Kai. ----------------- devices in dmesg ------------- mpt0: <LSILogic SAS/SATA Adapter> port 0x4000-0x40ff mem 0xfddf0000-0xfddf3fff,0xfdde0000-0xfddeffff irq 36 at device 0.0 on pci67 mpt0: [ITHREAD] mpt0: MPI Version=1.5.19.0 mpt0: Capabilities: ( RAID-0 RAID-1E RAID-1 ) mpt0: 0 Active Volumes (2 Max) mpt0: 0 Hidden Drive Members (14 Max) ciss0: <HP Smart Array P400> port 0x5000-0x50ff mem 0xfdf00000-0xfdffffff,0xfdef0000-0xfdef0fff irq 32 at device 0.0 on pci70 ciss0: [ITHREAD] da0 at mpt0 bus 0 target 8 lun 0 da0: <HP DG146ABAB4 HPDC> Fixed Direct Access SCSI-5 device da0: 300.000MB/s transfers da0: Command Queueing Enabled da0: 140014MB (286749488 512 byte sectors: 255H 63S/T 17849C) da2 at ciss0 bus 0 target 0 lun 0 da2: <COMPAQ RAID 5 VOLUME OK> Fixed Direct Access SCSI-5 device da2: 135.168MB/s transfers da2: Command Queueing Enabled da2: 26109MB (53472480 512 byte sectors: 255H 32S/T 6553C) da3 at ciss0 bus 0 target 1 lun 0 da3: <COMPAQ RAID 5 VOLUME OK> Fixed Direct Access SCSI-5 device da3: 135.168MB/s transfers da3: Command Queueing Enabled da3: 143357MB (293596800 512 byte sectors: 255H 32S/T 35980C) da1 at mpt0 bus 0 target 9 lun 0 da1: <HP DG146ABAB4 HPDC> Fixed Direct Access SCSI-5 device da1: 300.000MB/s transfers da1: Command Queueing Enabled da1: 140014MB (286749488 512 byte sectors: 255H 63S/T 17849C) da4 at ciss0 bus 0 target 2 lun 0 da4: <COMPAQ RAID 5 VOLUME OK> Fixed Direct Access SCSI-5 device da4: 135.168MB/s transfers da4: Command Queueing Enabled
