So I just finished upgrading to Yosemite on my server, and everything is running fine except for my RAIDs. I am running multiple RAIDs off port multipliers, using eSATA, running through a FirmTek TT-PX-Q86 via Thunderbolt. Since the Yosemite upgrade, I can't access my RAIDs, and in fact only one drive per port multiplier shows up in disk utility. Anyone else having this problem? Is there a fix?
