If I read this correctly your problem has nothing to do with ZFS.
It is plain recognizing the disk in the BIOS/RAID-card. And if it  
recognizes the disk it must recognize the boot-code.

Please send more information about your setup.
Output of /var/run/dmesg.boot.
Is your BIOS set to MBR, GPT, (U)EFI?
What is installed in your boot blocks (MBR, GPT or (U)EFI)?
What version of FreeBSD are you running?

Regards,
Ronald.
