STRUCT LEAPRAID_EXP_P0(9)

🌸 NAME 🌸

okay bestie, meet struct leapraid_exp_p0 — SAS expander page 0. This is the manual page struct leapraid_exp_p0(9) from the Kernel API Manual, and it is literally here to introduce the struct and its fields. 💅

✨ SYNOPSIS ✨

lowkey just a C struct, no cap:

       struct leapraid_exp_p0 {
           struct leapraid_cfg_ext_pg_header header;
           u8 physical_port;
           u8 r1;
           __le16 enc_hdl;
           __le64 sas_address;
           u8 r2[4];
           __le16 dev_hdl;
           __le16 parent_dev_hdl;
           u8 r3[4];
           u8 phy_num;
           u8 r4[27];
        };

🎀 Members 🎀

field-by-field, bestie — every single one is iconic in its own way:

• header — extended page header. 💖
• physical_port — physical port number.
• r1 — reserved.
• enc_hdl — enclosure handle.
• sas_address — SAS address of the expander.
• r2 — reserved. (in the struct it's a u8 r2[4])
• dev_hdl — device handle of this expander.
• parent_dev_hdl — device handle of parent expander.
• r3 — reserved. (in the struct it's a u8 r3[4])
• phy_num — number of PHYs.
• r4 — reserved. (in the struct it's a u8 r4[27])
