lpfc_hba_down_prep(9)

💅 lpfc_hba_down_prep(9) 💅

okay bestie, welcome to the lpfc_hba_down_prep(9) page from the Kernel API Manual ✨ this one is short, sweet, and lowkey important: it's the pre-reset uninit moment for the lpfc HBA. let's get into it 💖

---

🌸 NAME 🌸

lpfc_hba_down_prep — perform lpfc uninitialization prior to HBA reset 🫶

---

✨ SYNOPSIS ✨

int lpfc_hba_down_prep (struct lpfc_hba *phba );

---

🎀 ARGUMENTS 🎀

• phba — pointer to the lpfc HBA data structure. that's the main-character struct for this HBA, no cap 💅

---

🦋 DESCRIPTION 🦋

okay so this routine will do LPFC uninitialization before the HBA is reset when bringing down the SLI Layer. it's giving “clean up your room before the reset arc begins” energy 🧹✨

Return codes: 0 means success. Any other value means error. periodt 💀
