✨ mpt3sas_tra...xisting_port(9) ✨

okay bestie, so this is a page straight out of the Kernel API Manual, section 9 — and yes the topic is mpt3sas_transport_add_phy_to_an_existing_port, which is a whole mouthful, so we're gonna call it "the phy-to-port adder" and move on 💅

---

🌸 NAME 🌸

mpt3sas_transport_add_phy_to_an_existing_port — adding a new phy to an existing port, literally exactly what it says on the tin 🎀

---

🦋 SYNOPSIS 🦋

void mpt3sas_transport_add_phy_to_an_existing_port (struct MPT3SAS_ADAPTER *ioc , struct _sas_node *sas_node , struct _sas_phy *mpt3sas_phy , u64 sas_address , struct hba_port *port );

it returns void, so like… no return value, no drama, no notes. she just does the thing. periodt ✨

---

💖 ARGUMENTS 💖

• ioc — the per adapter object. this is the main character, the whole adapter's vibe container 👑
• sas_node — the sas node object, and it's giving "either expander or sas host" energy. two paths, one parameter, we love flexibility 🦋
• mpt3sas_phy — the mpt3sas per phy object. one phy, hers specifically, no sharing 🎀
• sas_address — the sas address of the device/expander where the phy needs to be added to. yes "were" in the original — we're keeping her exactly as she is, no corrections, she's iconic 😭
• port — the hba port entry. the destination. the home. the port she's moving into 🏠

and that's the whole page!! mwah 🫶 this lil slice of kernel lore lives in ./drivers/scsi/mpt3sas and got stamped October 2026 — so like, future-dated and still slaying ⭐💖
