💅 lpfc_scsi_prep_task_mgmt_cmd_s4(9) 💅

Okay so welcome to the Kernel API Manual page for lpfc_scsi_prep_task_mgmt_cmd_s4(9) — yes, the name is long, yes, it’s iconic, and yes, we’re getting into it 💖

---

🎀 NAME 🎀

lpfc_scsi_prep_task_mgmt_cmd_s4 — Convert SLI4 scsi TM cmd to FCP info unit.

That’s the whole vibe: this is the function that does that conversion. Slay ✨

✨ SYNOPSIS ✨

The signature is literally:

int lpfc_scsi_prep_task_mgmt_cmd_s4 (struct lpfc_vport *vport , struct
       lpfc_io_buf *lpfc_cmd , u64 lun , u8 task_mgmt_cmd );

🫶 ARGUMENTS 🫶

• vport — the virtual port that this call is running for, bestie 🦋
• lpfc_cmd — a pointer to the lpfc_io_buf data structure. Yep, exactly that 🎀
• lun — the logical unit number 🌸
• task_mgmt_cmd — the SCSI task management command 💅

💅 DESCRIPTION 💅

This routine creates the FCP information unit corresponding to task_mgmt_cmd for a device with the SLI-4 interface spec. That’s the main-character job of this function, fr fr 👑

Return codes: 0 - Error, 1 - Success 😭

Not me double-checking that: 0 is Error and 1 is Success. That is what the page says, bestie — read it twice if you need to 💀
