STRUCT ZFCP_UNIT(9)

💅 NAME 💅

okay so bestie, this is struct zfcp_unit(9) from the Kernel API Manual — and it's literally the LUN configured via zfcp sysfs. slay 💅✨

🦋 SYNOPSIS 🦋

here's the whole struct, no cap:

       struct zfcp_unit {
           struct device           dev;
           struct list_head        list;
           struct zfcp_port        *port;
           u64 fcp_lun;
           struct work_struct      scsi_work;
        };

🌸 Members 🌸

• dev — the struct device for sysfs representation and reference counting. it's giving sysfs main character energy 🎀
• list — entry in the LUN/unit list per zfcp_port.
• port — reference to zfcp_port where this LUN is configured.
• fcp_lun — the 64 bit LUN value. iconic.
• scsi_work — for running scsi_scan_target.

💖 Description 💖

This is the representation of a LUN that has been configured for usage. The main data here is the 64 bit LUN value, and data for running I/O and recovery is in struct zfcp_scsi_dev. so like, this struct is the configured-LUN vibe, and the I/O and recovery data lives over in struct zfcp_scsi_dev — iykyk 🫶
