catastrophic loss of disk labels after DC power outage

There was a complete power outage in a data center, and an intel R2000W server is now non-functional.
boot disk pair, on /dev/ata0 and ata1 are fine.
However, drives in the front bays, da0-da7 have no label.
Previously, they were all part of one zfs pool.

camcontrol sees the drives. I can also "dd if=/dev/da0".

however, "glabel list" does not see them, and neither does "zpool import"

I'm fairly new to freebsd, so any and all help would be appreciated.
This is FreeBSD 11.0p15
 
Doh...
thanks for the reply.
turns out there was hidden knowlege involved. the disks were encrypted with "geli" and needed to be unlocked after reboot.
