> Dear list,

> I have one Fujitsu server with LSI SAS 3108 RAID Controller. These  
> LSI SAS 3108 RAID Controller is supported by the mpr driver  
> (https://www.freebsd.org/relnotes/CURRENT/hardware/support.html).
> If I try to install the FreeBSD-stable 10.0 or FreeBSD-current 11.0  
> on this server I can make partitions, but I can not write install  
> files on the disks (better to say RAID5 virtual drive) without errors.
> The erorrs are:
> mfi0 failed to get command
> mfi0: COMMAND ... TIMEOUT AFTER  ... SECONDS
>
> By the installations I see my virtual drive as device with mfi0 as  
> identifier.
>
> My questions are:
> 1) Why I see the virtual drive as device with mfi0 as identifier. I  
> would expect that my virtual drive has identifier mpr0 or something  
> like this.
> 2) Why I can install FreeBSD on one of the disks connected to LSI  
> SAS 3108 RAID Controller, if the disks do not build any virtual  
> drive (no matter which RAID level). Is that possible because mpr  
> driver supports the LSI SAS 3108 RAID Controller as SCSI Controller  
> and not as RAID Controller (see Kernel configuration)?
