Does Lucid support hotswapping of AHCI devices? Is there anything more to it than simply unmounting all filesystems on the drive to be disconnected and plugging in the new disk?
00:1f.2 SATA controller: Intel Corporation 82801IR/IO/IH (ICH9R/DO/DH) 6 port SATA AHCI Controller (rev 02)
is the controller I'm working with.
BIOS is set to AHCI. I also tried simply unmounting and unplugging. That seemed to work fine. Plugging in a new drive locked up the system. AHCI kernel module is also loaded.
I've also looked at the Raid WIKI on kernel.org which talks about hardware requirements for AHCI HotSwapping of disks. My drives and cables all appear to meet the criteria, but most of that info pertains to the electrical side (grounding, etc...).
