scsih_scan_start(9)

okay so welcome to the Kernel API Manual, bestie ✨ today's main character is scsih_scan_start, and she is giving “host discovers its own targets” energy 💅

💖 NAME

scsih_scan_start — the scsi lld callback for .scan_start. That’s the whole vibe, no cap.

🦋 SYNOPSIS

void scsih_scan_start (struct Scsi_Host *shost );

Exact signature, bestie — don’t come for the spacing, it’s canon 💀

🎀 ARGUMENTS

• shost — SCSI host pointer. That’s the struct Scsi_Host * right there, periodt.

💜 DESCRIPTION

okay so the shost has the ability to discover targets on its own instead of scanning the entire bus. In our implemention (yes, that’s the spelling in the source, I’m just the messenger 🫶), we will kick off firmware discovery. It’s lowkey main character energy: the host does its own thing, firmware discovery starts, slay.

🌈 SEE ALSO

This is the whole squad, and yes we are listing every single one — no ghosting the references, bestie 💅

mwah 💋 this page lives in ./drivers/scsi/mpt3sas, the date vibe is October 2026, and the title stays scsih_scan_start(9) — mpt3sas girlies rise. periodt.
