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?
