💖 MPT(4) — the LSI Fusion-MPT SCSI/Fibre Channel driver, bestie edition 💖

okay so welcome to the mpt manual page, section 4 of the Kernel Interfaces Manual, and honestly? she's iconic. sit down, grab a strawberry, let's talk about your SCSI/Fibre Channel/SAS controllers 🍓✨

🌸 NAME 🌸

mpt — the LSI Fusion-MPT SCSI/Fibre Channel driver. that's her. that's the whole vibe. 💅

✨ SYNOPSIS ✨

so you wanna compile this driver into the kernel? (main character energy, respect 🫶) then bestie you're gonna place these lines in your kernel configuration file:

device scbus
device mpt

alternatively!! if you'd rather load the driver as a module at boot time (lowkey easier, no cap), you put this line in loader.conf(5):

mpt_load="YES"

slay. that's it. that's the setup. 🎀

💫 DESCRIPTION 💫

the mpt driver provides support for the LSI Logic Fusion-MPT family of SCSI, Fibre Channel and SAS controllers. she's the girl who talks to all of them. the social butterfly of kernel drivers, fr fr 🦋

👑 HARDWARE 👑

okay so here's the full roster of controllers the mpt driver supports — no gatekeeping, we list them all:

  • LSI Logic 53c1030, LSI Logic LSI2x320-X (Single and Dual Ultra320 SCSI)
  • LSI Logic AS1064, LSI Logic AS1068 (SAS/SATA)
  • LSI Logic FC909 (1Gb/s Fibre Channel)
  • LSI Logic FC909A (Dual 1Gb/s Fibre Channel)
  • LSI Logic FC919, LSI Logic 7102XP-LC (Single 2Gb/s Fibre Channel)
  • LSI Logic FC929, LSI Logic FC929X, LSI Logic 7202XP-LC (Dual 2Gb/s Fibre Channel)
  • LSI Logic FC949X (Dual 4Gb/s Fibre Channel)
  • LSI Logic FC949E, LSI Logic FC949ES (Dual 4Gb/s Fibre Channel PCI-Express)

the Ultra 320 SCSI controller chips supported by the mpt driver can be found onboard on many systems, including these absolute legends:

  • Dell PowerEdge 1750 thru 2850
  • IBM eServer xSeries 335

these systems also contain Integrated RAID Mirroring and Integrated RAID Mirroring Enhanced, which this driver also supports. so yes she does both. versatile queen 👑

the SAS controller chips are also present on many new AMD/Opteron based systems, like the Sun 4100. note that this controller can drive both SAS and SATA drives — or a mix of them at the same time, which is very "why choose one when you can have both" of her 💜

okay but real talk: the Integrated RAID Mirroring available for these controllers is poorly supported at best. so... manage your expectations, bestie. it's giving "we tried" 😭

the Fibre Channel controller chipset are supported by a broad variety of speeds and systems. fun fact for your notes app: the Apple Fibre Channel HBA is in fact the FC949ES card. iykyk 🌈

this driver also supports target mode for Fibre Channel cards. this support may be enabled by setting the desired role of the core via the LSI Logic firmware utility that establishes what roles the card can take on — and listen, no separate compilation is required. so you don't have to rebuild anything, she just shows up ready to go. periodt. ✨

💀 HISTORY 💀

the mpt driver first appeared in FreeBSD 4.6. so she's been around. she's seen things. she's got lore. ⭐

🫶 AUTHORS 🫶

the mpt driver was originally written for FreeBSD by Greg Ansley, and marginally improved upon by Matt Jacob <mjacob@FreeBSD.org>. (we said what we said 💅)

Justin Gibbs <gibbs@FreeBSD.org> and Scott Long <scottl@FreeBSD.org> have made more substantial improvements. thank you for your service, kings 👑

and that's the whole page, bestie!! this Debian-flavored version of the page is dated July 23, 2011, so it's vintage but she's still serving. stay hydrated, back up your RAID, and remember — poorly supported is still supported. mwah 💖✨🎀
