MPATH(4)

🌸 NAME 🌸

mpath — SCSI multipath. Bestie, this is the mpath(4) manual page, straight out of the Kernel Interfaces Manual, and it's literally the SCSI multipath driver. 👑

✨ SYNOPSIS ✨

emc* at scsibus?
hds* at scsibus?
rdac* at scsibus?
sym* at scsibus?

mpath0 at root

💅 DESCRIPTION 💅

Okay so mpath provides access, I/O multiplexing, and failover support to SCSI logical units that can have multiple physical connections to the system. That's the whole flex. 💖

It uses connections presented by path drivers — for example sym(4) — as backends to a single device attached to its own scsibus(4). No cap, that's just how it's set up. ✨

🦋 HISTORY 🦋
