NVME_GET_LOG_ROTATIONAL_MEDIA_INFO(2)

💖 nvme_get_log_rotational_media_info — the "where my spinning disks at" log 💖

okay bestie, so this is a page from the libnvme API manual, and today's main character is nvme_get_log_rotational_media_info. No cap, the name is a whole mouthful, but the vibe is simple: it goes and gets you the Rotational Media Information Log off your NVMe device. 🌀✨

✨ NAME ✨

nvme_get_log_rotational_media_info — Retrieve Rotational Media Information Log

Like... it literally does what it says. It retrieves the Rotational Media Information Log. Iconic behaviour honestly. 🫶

---

✨ SYNOPSIS ✨

int nvme_get_log_rotational_media_info (int fd , __u16 endgid , __u32 len , struct nvme_rotational_media_info_log *log );

---

✨ ARGUMENTS ✨

• fd — the file descriptor of the nvme device. this is your VIP pass into the device, your backstage wristband, your "i belong here" energy. 🎀
• endgid — Endurance Group Identifier. it's a __u16, it picks which endurance group you're asking about. lowkey specific, highkey important. 💅
• len — the allocated length of the log page. you gotta tell it how much room you made. it's a __u32, so it's got range. 🌈
• log — user address to store the log page. it's a struct nvme_rotational_media_info_log *, and this is where the tea gets poured. 🍓

---

✨ RETURN ✨

So here's the deal: you get the nvme command status if a response was received — go peek at enum nvme_status_field for the full lore — or you get -1 with errno set otherwise. that's it, that's the whole energy. no response from the device = -1 + errno, and you go read errno like it's a group chat you missed. 😭

ngl, if you see a -1, do not just vibe past it. check errno. fr fr, always check errno.

and that's the page bestie!! 💜 this lil writeup lives in the libnvme API manual, and it's dated July 2026 — so yeah, freshly stamped, main character energy, off you go. go get that log. slay. 👑💖
