Yes, you can specifically boot from the alternate disk.
I have an x4270m2 so I'm not sure what kind of disks you have.
You'll have to consider the device differences.
Here's my mirrored root pool:
# zpool status

I would need to boot this system specifically from the second disk,
c0t5000C500438124F3d0, from the system's BIOS.
Then, you can identify from which disk the system is currently booted,
# prtconf -v|sed -n '/bootpath/,/value/p'
