STRUCT ZFCP_DBF_REC(9)

✨ struct zfcp_dbf_rec(9) ✨

okay so bestie, welcome to the Kernel API Manual 💖 this one's all about struct zfcp_dbf_rec — literally the trace record for error recovery actions. no cap, it's the receipts your kernel keeps when things go sideways and recovery kicks in. let's get into it 🫶

---

🌸 NAME 🌸

struct zfcp_dbf_rec — trace record for error recovery actions. that's the whole vibe: it's the record that documents the recovery drama 💅

---

🎀 SYNOPSIS 🎀

struct zfcp_dbf_rec {
    u8 id;
    char tag[ZFCP_DBF_TAG_LEN];
    u64 lun;
    u64 wwpn;
    u32 d_id;
    u32 adapter_status;
    u32 port_status;
    u32 lun_status;
    union {
      struct zfcp_dbf_rec_trigger trig;
      struct zfcp_dbf_rec_running run;
    } u;
 };

like, that's the whole struct, laid out exactly like that — every field, every nesting level, untouched. iykyk 💜

🦋 Members 🦋

• id — the unique number of the recovery record type. it's giving "which flavor of recovery is this" energy ⭐
• tag — an identifier string that specifies the location of initiation. basically the "where did this start" stamp 🎀
• lun — the logical unit number.
• wwpn — word wide port number.
• d_id — destination ID.
• adapter_status — the current status of the adapter.
• port_status — the current status of the port.
• lun_status — the current status of the lun.
• u — record type specific data. it's a union, so it's one or the other, bestie 🙈
• u.trig — structure zfcp_dbf_rec_trigger.
• u.run — structure zfcp_dbf_rec_running.

lowkey important: u is a union — trig and run share that space, so you're looking at one of them per record, not both at once 💀
