mpi3mr_update_links(9)

💫 mpi3mr_update_links(9) 💫

okay so this is a page from the Kernel API Manual, and honestly? it's a whole little glow-up for SAS phys. stay with me bestie 🫶

---

✨ NAME ✨

mpi3mr_update_links — refreshing SAS phy link changes 💅

---

🌸 SYNOPSIS 🌸

void mpi3mr_update_links (struct mpi3mr_ioc *mrioc , u64
sas_address_parent , u16 handle , u8 phy_number , u8 link_rate , struct
mpi3mr_hba_port *hba_port );

no cap, that's the whole signature — void return, six args, we move 💫

---

🎀 ARGUMENTS 🎀

• mrioc — your adapter instance reference. it's giving "who am I doing this for" energy 🌈
• sas_address_parent — the SAS address of the parent expander or the host. like, where this phy lives, iykyk 🦋
• handle — the firmware device handle of the attached device. the firmware's own little ID tag for the device 🔥
• phy_number — the phy number. yes, that's it. that's the whole description 💀
• link_rate — the new link rate. this is the actual change we're refreshing ✨
• hba_port — the HBA port entry 👑

---

⭐ RETURN ⭐

None.

literally nothing comes back. void stays undefeated 💜

that's the whole page, bestie — no hidden lore, no extra options, just a clean little phy-refresh function doing its thing 🍓

mwah 💋 this one shipped out of ./drivers/scsi/mpi3mr, dated October 2026, and it lives in the manual as mpi3mr_update_links(9) — catch you in the next one, love u, bye! 🎀💖
