libnvme(2)

✨ NAME ✨

okay bestie, welcome to the libnvme manual, section 2 💖 today's main character is:

struct nvme_ana_group_desc — ANA Group Descriptor 🎀

that's it. that's the whole vibe. ANA = Asymmetric Namespace Access, iykyk, and this struct is the little descriptor that tells you about one ANA group. she's small, she's structured, she's giving organized ✨

---

🌸 SYNOPSIS 🌸

struct nvme_ana_group_desc {
    __le32 grpid;
    __le32 nnsids;
    __le64 chgcnt;
    __u8 state;
    __u8 rsvd17[15];
    __le32 nsids[];
};

look at her 🥹 so clean, so precise, no notes. literally the blueprint.

💅 Members 💅

okay so this is the part where we meet the cast, one by one, struct member by struct member, no skipping, periodt.

• grpid — the ANA group id. her name tag at the party 🎀
• nnsids — how many namespaces live in nsids. the headcount, fr fr 👑
• chgcnt — the change counter. she keeps track of every glow-up ✨
• state — the ANA state. her current mood, essentially 💅
• rsvd17 — reserved. do not touch, do not look at her, she is simply occupying space 🙈
• nsids — the list of namespaces. the whole squad, assembled 🦋

---

ngl bestie, a reserved field is reserved for a reason — leave rsvd17 alone, she's not for you 💀

and that's the page!! 🫶 this was libnvme, API Manual, section 2, and the whole thing got stamped with July 2026 and lives under the name struct nvme_ana_group_desc ⭐ so if you ever see the date July 2026 floating around in your man pages, that's just her little signature, no cap 💖 byeee, go read some more structs, mwah 😭🎀
