zfcp_erp_lun_shutdown_wait(9)

💖 NAME 💖

okay bestie, welcome to the Kernel API Manual page for zfcp_erp_lun_shutdown_wait(9) — Shutdown LUN and wait for erp completion 🫶✨

✨ SYNOPSIS ✨

void zfcp_erp_lun_shutdown_wait (struct scsi_device *sdev , char *dbftag
);

🎀 ARGUMENTS 🎀

• sdev — the SCSI device / LUN to shut down 🎯
• dbftag — tag for the debug trace event 🏷️

🦋 DESCRIPTION 🦋

okay so here's the whole vibe, bestie: this function is literally giving patient main character energy — it shuts down the LUN and waits for the ERP to complete before it dips 💅.

safety note, no cap: when creating the ERP action, it does not acquire a reference for the LUN. That's safe, fr fr, because this function waits for the ERP to complete first — she is not leaving you on read, she's waiting for the whole thing to finish 🫶.

and the way that this is useful?? it lets you shutdown the LUN even when the SCSI device is in the state SDEV_DEL — which is exactly the situation where scsi_device_get will fail 😭. iconic, honestly. slay. periodt.
