🌸 NAME 🌸

okay bestie, this is qla4xxx_reset_lun(9) from the Kernel API Manual, and it is literally the function that issues a LUN Reset. main character energy for a reset routine, ngl. 💅

✨ SYNOPSIS ✨

int qla4xxx_reset_lun (struct scsi_qla_host * ha , struct ddb_entry * ddb_entry , uint64_t lun );

🎀 ARGUMENTS 🎀

• ha — pointer to the host adapter structure. that's your host adapter bestie, the big-picture handle. 🫶
• ddb_entry — pointer to the device database entry. yes, the ddb entry, keep up. 💖
• lun — lun number. just the lun number, periodt.

🔥 DESCRIPTION 🔥

so this routine performs a LUN RESET on the specified target/lun. that's the whole move. ✨
