I didn't need to do anything special when inserting disks into my
(cheap) 4x 2.5" SATA hot swap bay. Just inserted the drive and the
HAL/udev deamon pick it up all on its own. My motherboard is a
nVidia-based:
00:09.0 SATA controller: nVidia Corporation MCP78S [GeForce 8200] AHCI Controller (rev a2)
And I am using the AHCI driver. CentOS 5.4, x86_64 (xen).
It could be that the SATA controller on your motherboard does not
support hotswap detection (not all AHCI controllers support hotswap
detection).
