https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=3D251483 --- Comment #6 from Doug Ambrisko <ambrisko@FreeBSD.org> --- I never figured out what this code was dealing with. It came from LSI/Avago/Broadcom with their initial support of Thunderbolt family of RAID cards. This was before they decided to make mrsas. That is why I put in t= he printf. I assume that the CLI was MegaCLI. Note that the MFI_CMD_PD_SCSI_= IO is for commands going to the raw disk versus to the RAID volume. This shou= ld mostly be handled as a "SYSPDIO" which they called system physical disk IO, which is a talking straight to the disk. That is handled the "mfisyspd" of= the driver. it's kind of strange mode. The real fix is probably to remove the cdb[0] !=3D 0x28 && cdb[0] !=3D 0x2A and always run mfi_tbolt_build_mpt_cmd and not fall through to "DJA NA XXX SYSPDIO". I never found out why we would need to do that check. I put that message there so if it happened we can try to figure out why. Since I've n= ever seen that happen we can probably remove it. --=20 You are receiving this mail because: You are the assignee for the bug.=
