The cmdk (and pci-ide) in device paths suggest IDE (emulated?) disk access; I am not sure the protocol supported more than some limit that was infinite-like in 90's or so.

Can you place it to SATA (possibly changing BIOS settings, and at a risk of loading with live media to export-import rpool with new device paths)?
