💅 lpfc_send_taskmgmt(9) — Generic SCSI Task Mgmt Handler 💅

okay bestie, welcome to the kernel API manual for lpfc_send_taskmgmt(9) — yes, it’s giving very specific kernel energy, and we’re gonna understand it together. 🫶

✨ NAME ✨

lpfc_send_taskmgmt — Generic SCSI Task Mgmt Handler. That’s the whole name, no cap.

---

💅 SYNOPSIS 💅

int lpfc_send_taskmgmt (struct lpfc_vport *vport , struct fc_rport
       *rport , unsigned int tgt_id , uint64_t lun_id , uint8_t task_mgmt_cmd
       );

---

🌸 ARGUMENTS 🌸

• vport — the virtual port this call is being executed for, bestie.
• rport — pointer to the remote port.
• tgt_id — Target ID of the remote device.
• lun_id — Lun number for the TMF.
• task_mgmt_cmd — the type of TMF to send.

---

🦋 DESCRIPTION 🦋

okay so this routine builds and sends a TMF — that’s a SCSI Task Mgmt Function — to a remote port. That’s literally the whole job. ✨

Return code tea ☕: 0x2003 means Error, and 0x2002 means Success. Yes, those are the numbers, memorize them iykyk.
