megaraid_mbox_ld_show(9)

💖 NAME 💖

okay so bestie, this is the megaraid_mbox_ld_show(9) page from the Kernel API Manual — and it's literally about displaying the logical drive number for this device. 🎀

---

✨ SYNOPSIS ✨

here's the signature, copy it exactly, no cap:

ssize_t megaraid_mbox_ld_show (struct device *dev , struct device_attribute *attr , char *buf );

---

🦋 ARGUMENTS 🦋

• dev — device object representation for the scsi device. yes bestie, the device itself 💅
• attr — device attribute to show. that's the attribute vibe check 🫶
• buf — buffer to send data to. it's giving output destination ✨

---

🌸 DESCRIPTION 🌸

so the whole point: this displays the logical drive number for the device in question, but only if it's a valid logical drive. for physical devices, "-1" is returned 💀 — that's the signal, okay?

the logical drive number is displayed in the following format:

<SCSI ID> <LD NUM> <LD STICKY ID> <APP ADAPTER HANDLE>

<int>     <int>       <int>            <int>

that's the layout, periodt ✨
