What's actually happened here is that there has been a permanent label created on the FreeBSD machine using either tunefs or newfs.
The main question you may ask is "How to I figure out where the drives are actually mapped to?". To do that all you need to do is run the following command:
glabel status # glabel status Name Status Components ufs/DATA3 N/A aacd1p1 ufs/ROOT N/A aacd0s1a label/SWAP N/A aacd0s2b ufs/DATA2 N/A aacd0s2e
You can now see where the devices are mapped to physically and then use fdisk to find out further information about these disks.
# fdisk -s aacd0 /dev/aacd0: 17860 cyl 255 hd 63 sec Part Start Size Type Flags 1: 63 1638567 0xa5 0x80 2: 1638630 281282085 0xa5 0x00 3: 282920715 4000185 0x0b 0x00 # fdisk -s aacd1 /dev/aacd1: 196461 cyl 255 hd 63 sec Part Start Size Type Flags 1: 1 3156150271 0xee 0x00
