STRUCT ZFCP_DBF_REC_RUNNING(9)

💅 struct zfcp_dbf_rec_running(9) — Kernel API Manual

okay so bestie, this is a page straight out of the kernel API manual, and it's literally about a struct in the Linux kernel — ngl, it's giving "small but mighty" energy. It's the trace record for running recovery, and yes, that's the whole vibe. 🎀

✨ NAME ✨

struct zfcp_dbf_rec_running — trace record for running recovery

like, it's the lil snapshot that records a recovery while it's actively running. main character energy fr fr 💫

---

🌸 SYNOPSIS 🌸

struct zfcp_dbf_rec_running {
    u64 fsf_req_id;
    u32 rec_status;
    u16 rec_step;
    u8 rec_action;
    u8 rec_count;
 };

there she is 😭 five members, all lined up, all serving exactly what they need to serve. no notes.

👑 Members 👑

okay bestie, let's go through each one, one at a time, no skipping, we don't do that here:

• fsf_req_id — the request id for fsf requests. it's the lil name tag so you know which fsf request this is about 🏷️
• rec_status — the status of the fsf request. basically, how's it doing? are we good? are we not? this field knows 💀
• rec_step — the current step of the recovery action. like a progress bar but make it a u16 ⭐
• rec_action — the ERP action type. it's a u8, it's tiny, it's iconic, it tells you what kind of recovery action we're dealing with 🦋
• rec_count — the number of recoveries including retries for that particular rec_action. so like, how many times have we tried this specific thing, retries and all 👀

lowkey important: these fields are the only fields, so don't go looking for extras, there are none, the struct said what it said 💅

🔥 SEE ALSO 🔥

okay so this is the part where the manpage just lists literally everyone in the group chat, and honestly? respect. it's a whole friend group of zfcp dbf structs and enums, and they all live in the same kernel file, ./drivers/s390/scsi/zfcp_dbf.h:

• struct zfcp_dbf_rec_trigger(9)
• enum zfcp_dbf_rec_id(9)
• struct zfcp_dbf_rec(9)
• enum zfcp_dbf_san_id(9)
• struct zfcp_dbf_hba_res(9)
• struct zfcp_dbf_hba_uss(9)
• struct zfcp_dbf_hba_uas(9)
• struct zfcp_dbf_hba_fces(9)
• enum zfcp_dbf_hba_id(9)
• struct zfcp_dbf_hba(9)
• enum zfcp_dbf_scsi_id(9)
• struct zfcp_dbf_scsi(9)
• struct zfcp_dbf_pay(9)
• struct zfcp_dbf(9)
• zfcp_dbf_hba_fsf_resp_suppress(9)
• zfcp_dbf_hba_fsf_response(9)
• zfcp_dbf_scsi_result(9)
• zfcp_dbf_scsi_fail_send(9)
• zfcp_dbf_scsi_abort(9)
• zfcp_dbf_scsi_devreset(9)
• zfcp_dbf_scsi_nullcmnd(9)

and the kernel file they all call home is ./drivers/s390/scsi/zfcp_dbf.h. periodt. 💖

that's the whole page bestie, you ate that 🫶 this one's from ./drivers/s390/scsi, dated October 2026, and it's filed under struct zfcp_dbf_rec_running(9) — go off, king 🌈✨
