📦 version 7.3.1, in nixpkgs unstable

💅 mpt3sas_scs...nd_by_handle(9) — hey bestie, welcome to the Kernel API Manual, section 9 ✨

okay so real talk, this page is about the function mpt3sas_scsih_expander_find_by_handle, and yes the title got squished by the man-page machinery, we don't ask questions 🫶. It lives in section 9 of the Kernel API Manual and it's giving "small function, big friend group" energy. Let's go 💖

✨ NAME ✨

mpt3sas_scsih_expander_find_by_handle — the expander device search, aka "bestie, go find that expander for me" 🔍

🌸 SYNOPSIS 🌸

struct _sas_node * mpt3sas_scsih_expander_find_by_handle (struct
MPT3SAS_ADAPTER *ioc , u16 handle );

no cap, that's the whole signature. she takes two things and gives you back a struct _sas_node * 🎀

🦋 ARGUMENTS 🦋

  • ioc — the per adapter object. like, YOUR adapter. the one you're working with. main character energy 👑
  • handle — the expander handle (assigned by firmware). firmware handed this number out, so you're just rolling with it ✨

💜 CONTEXT 💜

⚠️ heads up bestie: the calling function should acquire ioc->sas_device_lock. yes, should. please lock it. do not be the person who skips the lock, i am begging 😭🔒

🧚 DESCRIPTION 🧚

So what does she actually do? This searches for an expander device based on handle, then returns the sas_node object. That's it. That's the whole vibe. search by handle → get sas_node → slay 💅

ngl it's a short man page but the SEE ALSO list is enormous, so buckle up 🍓

🔥 SEE ALSO 🔥

Kernel file ./drivers/scsi/mpt3sas/mpt3sas_scsih.c and honestly the whole extended friend group:

like… that's the whole mpt3sas extended universe, i'm obsessed 😭💖

and that's the page!! this lil gem comes to you from ./drivers/scsi/mpt3sas, dated October 2026, and it's part of the Kernel API Manual — go forth and find those expanders, bestie 🦋✨💅
