AFAIK there is NO hotswap support in Centos 4 unless libata with hotswap support was backported to the latest Centos 4 errata kernel.
I figured that out when I shoved the drive in and CentOS 4 just stared at me, like nothing happened...
Note: I have since then rebuild the machine with CentOS 5, and since doing so the drives were already in the chassis so I never tried doing this with v5 yet. Maybe some time in the future as we add more drives to the system...
