💅 megaraid_reset_handler(9) 💅

okay so real talk, this page lives in the Kernel API Manual (that's the manual name, bestie, don't @ me), and it's all about megaraid_reset_handler — the device reset handler for the mailbox based driver. yes that's a mouthful. we're getting through it together 🫶

---

✨ NAME ✨

megaraid_reset_handler — the device reset handler for the mailbox based driver, periodt 🔥

---

🌸 SYNOPSIS 🌸

int megaraid_reset_handler (struct scsi_cmnd *scp );

---

🎀 ARGUMENTS 🎀

• scp — the reference command 💖 like, the command that's our reference point for the whole little reset adventure

---

🦋 DESCRIPTION 🦋

So this is the reset handler for the mailbox based controller. When stuff goes sideways, this is the girl who picks up the phone 📞

First thing it does? Tries to figure out if the FW is still live. and if it is (slay), then the outstanding commands counter mut go down to 0. 👀 (yes, the original says "mut" — that's canon, we don't fix canon, iykyk)

And if that happens — if the counter actually goes down to 0 — then it also issues the reservation reset command, so it can relinquish (possible) reservations on the logical drives connected to this host. giving very much "cleaning up my own mess" main character energy ✨🧹

no cap, the whole flow is: check if FW is live → outstanding commands counter goes to 0 → then issue the reservation reset command to let go of (possible) reservations on the logical drives hooked up to this host. that's it. that's the vibe check 💅
