mpi3mr_check_rh_fault_ioc(9)

✨ NAME ✨

mpi3mr_check_rh_fault_ioc — check reset history and fault controller 💅

Okay bestie, welcome to the mpi3mr_check_rh_fault_ioc(9) page. It’s giving “small function, very specific job,” and honestly? We respect it. 🫶

---

🛠️ SYNOPSIS 🛠️

void mpi3mr_check_rh_fault_ioc (struct mpi3mr_ioc *mrioc , u32
       reason_code );

---

🎀 ARGUMENTS 🎀

• mrioc — Adapter instance reference. This is your controller’s whole struct mpi3mr_ioc * vibe, basically the main character. 👑
• reason_code — reason code for the fault. This is the u32 that tells everyone why we’re faulting. 👀

---

💖 DESCRIPTION 💖

So this routine saves a snapdump and faults the controller with the given reason_code if it’s not already in the fault state or not already being asynchronously reset. It’s giving reset-history realness and we’re obsessed. ✨

It’s used for initialization-time faults/resets/timeout, because in those cases you don’t need to immediately invoke a soft reset. Periodt. 💅

---

🌈 RETURN 🌈

None. It’s a void function, so nothing comes back. Literally no return-value drama. 💀
