To the best of my knowledge, you can not change disk adapter or disk
drive names in FreeBSD. The only way I know, is to change the physical
locations of host bus adapters and moving the SATA cables between
drives.
I would either change the swap device name in /etc/fstab or label the
swap device, which may require you to repartitioning of the swap device,
because glabel(8) uses the last sector.
Best regards,
Esa
