scsi_vpd_tpg_id(9)

💅 scsi_vpd_tpg_id 💅

okay bestie, welcome to the Kernel API Manual page for scsi_vpd_tpg_id — yes it's a mouthful, yes you're gonna say it three times fast and get it wrong, and yes it's lowkey iconic 🎀

---

✨ NAME ✨

scsi_vpd_tpg_id — return a target port group identifier 👑

🌸 SYNOPSIS 🌸

int scsi_vpd_tpg_id (struct scsi_device *sdev , int *rel_id );

🦋 ARGUMENTS 🦋

• sdev — the SCSI device. like, the whole reason we're here 🫶
• rel_id — a pointer where the relative target port gets stashed if it's not NULL. so like, optional bestie, no pressure 💅

💖 DESCRIPTION 💖

So what this does: it returns the Target Port Group identifier, pulled straight from the info living in VPD page 0x83 of the device. that's the vibe check ✨

And optionally — on success — it'll set rel_id to the relative target port. success only, okay? don't come for me if it didn't work 😭

🔥 RETURN 🔥

It returns the identifier itself, or an error on failure. that's it. that's the tea 💀
