I'm trying to get real hotplugging to work. My motherboard uses the Via VT8251 southbridge which, according to the whitesheet, supports SATA hotplugging: http://www.via.com.tw/en/downloads/whitepapers/chipsets/southbridge/chipsets_vt8251.pdf I set the SATA controller to the AHCI mode in my BIOS. When I unplug the drive, I see subdisk8: detached ad8: detached but plugging it back in, I don't see anything, and atacontrol list doesn't list any devices on the channel. If I do atacontrol reinit ata<number>, nothing happens, but if I do atacontrol detach ata<number> (it fails without detaching, first) atacontrol attach ata<number>, the drive is recognized ata4: [ITHREAD] ad8: ... Master: ... Slace: no device present How can I avoid all this and get the drive to be recognized automatically? Can I do this with devd? Did I do what I needed to correctly set up hotplugging?
