lpfc_oas_lun_get_next(9)

💅 lpfc_oas_lun_get_next — the lpfc_oas_lun_get_next(9) glow-up

okay so bestie, welcome to the Kernel API Manual corner of the group chat 💖 this one's about lpfc_oas_lun_get_next, and yes the name is a mouthful, no cap. She's out here finding LUNs that are enabled for Optimized Access Storage (OAS) operations — literally the "next up" bouncer for your storage 💅

---

✨ NAME ✨

lpfc_oas_lun_get_next — get the next lun that has been enabled for Optimized Access Storage (OAS) operations. periodt.

---

🦋 SYNOPSIS 🦋

uint64_t lpfc_oas_lun_get_next (struct lpfc_hba *phba , uint8_t
vpt_wwpn[] , uint8_t tgt_wwpn[] , uint32_t *lun_status , uint32_t
*lun_pri );

---

🌸 ARGUMENTS 🌸

• phba — an lpfc_hba pointer. the main character struct, honestly 👑
• vpt_wwpn — wwpn of the vport associated with the returned lun
• tgt_wwpn — wwpn of the target associated with the returned lun
• lun_status — status of the lun returned lun (yes it says "returned lun" twice, she's quirky like that, we keep it) 🙈
• lun_pri — priority of the lun returned lun

---

🔥 DESCRIPTION 🔥

So the way this works 🫶: she returns the first or next lun enabled for OAS operations, for the vport/target you specify. Iconic behavior, no notes.

If a lun is found, its vport wwpn, target wwpn and status is returned. Chef's kiss ✨

If the lun is not found, NOT_OAS_ENABLED_LUN is returned — that's the vibe check failing, and it's giving "nothing here bestie" 💀

---

⭐ RETURN ⭐

She gives you back the lun that is OAS enabled for the vport/target, and NOT_OAS_ENABLED_LUN when no oas enabled lun found. that's it, that's the deal 🌈
