pdc_get_initiator(9)

🌸 NAME 🌸

okay bestie, welcome to the Kernel API Manual page for pdc_get_initiator(9) — the manual name is literally right here so you never get lost 💖.

pdc_get_initiator — Get the SCSI Interface Card params (SCSI ID, SDTR, SE or LVD). That's the whole name vibe. 🎀

---

✨ SYNOPSIS ✨

       int pdc_get_initiator (struct hardware_path *hwpath , struct
       pdc_initiator *initiator );

That signature is doing main character energy: hwpath goes in, initiator gets the glow-up result. 💅

---

🎀 ARGUMENTS 🎀

• hwpath — fully bc.mod style path to the device. like, the whole path bestie.
• initiator — the array to return the result into. yes, it gets the results.

---

💅 DESCRIPTION 💅

Okay so this one literally gets the SCSI operational parameters from PDC. Needed since HPUX never used BIOS or symbios card NVRAM. periodt. 🫶

Most ncr/sym cards won't have an entry and just use whatever capabilities of the card are (eg Ultra, LVD). lowkey iconic of them. But there are several cases where it's useful:

• to set the SCSI id for Multi-initiator clusters
• when the cable is too long (ie SE scsi 10Mhz won't support 6m length) not the long-cable slay, bestie
• when the bus width exported is less than what the interface chip supports
