🌸 mptsas_find_...hys_disk_num(9) 🌸

okay so bestie, you're in the Kernel API Manual and this page is literally all about mptsas_find_phyinfo_by_phys_disk_num — the manual name got cut off in the header (iykyk, it happens 💅), but we're here now and we're gonna learn it together.

---

✨ NAME ✨

mptsas_find_phyinfo_by_phys_disk_num — find phyinfo for the specified @phys_disk_num

like, that's the whole vibe. you give it a physical disk number and it goes and finds you the phyinfo. no cap. 🦋

---

🎀 SYNOPSIS 🎀

struct mptsas_phyinfo * mptsas_find_phyinfo_by_phys_disk_num
(MPT_ADAPTER *ioc , u8 phys_disk_num , u8 channel , u8 id );

four args, one pointer back, slay. keep the spacing exactly like that, it's giving "generated by a script and we respect it" 💖

---

👑 ARGUMENTS 👑

okay these are the four besties you have to hand over when you call this function. let's do a lil vibe check on each one:

• ioc — Pointer to MPT_ADAPTER structure. this is the main character of the whole file honestly, everything points back to it. 🔥
• phys_disk_num — (hot plug) physical disk number (for RAID support). yes the "(hot plug)" is part of the description, don't come for me, and yes it's specifically for RAID support. 🫶
• channel — channel number. short, sweet, iconic. ⭐
• id — Logical Target ID. the target, but make it logical. ✨

and before you go — cute lil sign-off: this one lives under ./drivers/message/fusion, it's dated October 2026, and the page name on the tin is mptsas_find_...hys_disk_num(9) (the dots are canon, we don't question the dots 🌈). periodt. 🎀
