PROBE::SCSI.SET_ST(3stap)

✨ PROBE::SCSI.SET_ST ✨

okay bestie, welcome to the SCSI Tapset corner of the SystemTap manual (section 3stap, iykyk) 🦋 this little page is literally just about one probe, and honestly? it's kind of a big deal.

---

🌸 NAME 🌸

probe::scsi.set_state — Order SCSI device state change 👑

like, it's the probe that fires when a SCSI device's state is being changed. it does not do the changing. it orders it. main character energy fr fr.

---

🎀 SYNOPSIS 🎀

probe scsi.set_state {}

no arguments, no parameters, just vibes. she takes nothing and gives you everything 💅

---

💖 VALUES 💖

these are all the things you can read inside the probe. every single one, no skipping, we're not that kind of girl:

• state — the new state of the device. the glow-up it's about to have ✨
• old_state_str — the current state of the device, but as a string. the before picture, in words 🎀
• host_no — the host number. which host is hosting, basically 🫶
• state_str — the new state of the device, as a string. the after picture, in words 🌸
• channel — the channel number. the lane she's riding in 🌈
• lun — the lun number. yes, lun. that's the field name, we don't make the rules 💀
• old_state — the current state of the device. the before picture, but not a string 😭
• dev_id — the scsi device id. her government name, fr fr ⭐

so like, you get the old state twice (once as a number-ish old_state, once as a string old_state_str) and the new state twice (state and state_str). iconic of her honestly, always giving you options 💜
