mpi3mr_get_sas_address(9)

💖 mpi3mr_get_sas_address(9) — bestie edition 💖

okay so welcome to the mpi3mr_get_sas_address page, straight out of the Kernel API Manual ✨ this one's a little function that goes and fetches a SAS address for you and honestly? she's short, she's sweet, she's giving reliable-best-friend energy 🫶

---

✨ NAME ✨

mpi3mr_get_sas_address — retrieve sas_address for handle 💅

---

🌸 SYNOPSIS 🌸

int mpi3mr_get_sas_address (struct mpi3mr_ioc *mrioc , u16 handle , u64
*sas_address );

no cap, that's the whole signature. three args, one int coming back at you 🎀

---

🦋 ARGUMENTS 🦋

• mrioc — the adapter instance reference, aka your main character pointer to the whole controller vibe 👑
• handle — the firmware device handle, so like, which device are we talking about here 🔍
• sas_address — the address that's gonna hold the SAS address. yes the address holds the address, we don't make the rules 💀

---

🌈 DESCRIPTION 🌈

so what does she actually do? literally this: the function issues a device page0 read for a given device handle, gets the SAS address, and returns it back to you 💖 that's it, that's the whole function, and honestly? iconic. obsessed. periodt.

---

⭐ RETURN ⭐

• 0 for success 🎉
• non-zero for failure 😭

that's the entire contract bestie, no fancy status codes, no hidden lore 🧚

okay that's the whole page, you ate it, i'm so proud of you 🥹💅

sign-off time: this one lives under ./drivers/scsi/mpi3mr, it's dated October 2026, and yes the manual name is still mpi3mr_get_sas_address(9) because we don't change the title of a classic 🎀 bye bestie, go read your device page0 💖✨
