STRUCT LEAPRAID_SAS_DEV(9)

💅 struct leapraid_sas_dev(9) — literally the SAS device structure, bestie

okay so real talk, this is a page straight out of the Kernel API Manual, and it's all about struct leapraid_sas_dev — the SAS device structure. it's giving "one struct to track them all" energy and honestly? iconic. 🦋

✨ SYNOPSIS

struct leapraid_sas_dev {
    struct list_head list;
    struct scsi_target *starget;
    struct leapraid_card_port *card_port;
    struct sas_rphy *rphy;
    struct kref refcnt;
    unsigned int id;
    unsigned int channel;
    u16 slot;
    u8 phy;
    u8 resp;
    u8 led_on;
    u64 sas_addr;
    u64 dev_name;
    u16 hdl;
    u64 parent_sas_addr;
    u16 enc_hdl;
    u64 enc_lid;
    u16 volume_hdl;
    u64 volume_wwid;
    u32 dev_info;
    u8 pend_sas_rphy_add;
    u8 enc_level;
    u8 port_connection;
    u8 connector_name[LEAPRAID_SAS_DEV_P0_CON_NAME_LEN + 1];
};

like, look at her. 24 fields. main character energy fr fr. 👑

🎀 Members

okay so let's go member by member, no skips, no cap — every single one is here:

• list — the list head for device management. it's how the device keeps its little social circle together 💅
• starget — the SCSI target structure. yes bestie, a struct scsi_target *.
• card_port — the associated card port.
• rphy — the SAS remote PHY. struct sas_rphy * if you're keeping track 🦋
• refcnt — the reference count. a struct kref, keeping things alive (or letting them go 😭).
• id — the device ID. unsigned int.
• channel — the SCSI channel. also unsigned int.
• slot — the slot number, a u16.
• phy — the PHY identifier, a lil u8.
• resp — the response status. another u8.
• led_on — the LED state ✨ (a u8, as a treat).
• sas_addr — the SAS address, u64 and proud.
• dev_name — the device name. also u64, don't ask questions.
• hdl — the device handle, u16.
• parent_sas_addr — the parent SAS address. u64. family tree moment 🌸
• enc_hdl — the enclosure handle, u16.
• enc_lid — the enclosure logical ID, u64.
• volume_hdl — the volume handle, u16.
• volume_wwid — the volume WWID, u64.
• dev_info — the device information, u32.
• pend_sas_rphy_add — the pending SAS remote PHY addition flag. yes that's the whole vibe, a u8 saying "not yet bestie" 🙈
• enc_level — the enclosure level, u8.
• port_connection — the port connection, u8.
• connector_name — the connector name. it's declared as u8 connector_name[LEAPRAID_SAS_DEV_P0_CON_NAME_LEN + 1]; — array sized off that macro plus one, periodt.

that's the whole page bestie, go read the header file and slay 💜

so anyway, this page comes from the ./drivers/scsi/leapraid corner of the kernel, and the manual fairy stamped it October 2026 — that's the version and date, you're welcome, mwah 🎀✨
