So turns out the motherboard wasn't set to AHCI, which is why hotswap wasn't working. Fixed that, rebooted, and now the disk is seen. Let's resync those mirrors!
I wonder why this SiI card wasn't detecting the disk. The card, itself, was detected and the sata-sil driver loaded. But no disk showed up. Hmm.
(Not sure if I've ever used this card under CentOS 6 or if it was CentOS 5. Pretty sure it was a different motherboard).
This 'cheap' solution could turn out to be expensive!
