Your zpool „tank“ consists of sliced disks (note the s1 at the end of the device names)!
This is uncommon (only the disk that the system is booted from needs to have a slice because grub needs it).

The error message is correct. You have c3t4d0s1 in your zpool, not c3t4d0!
When you created your „tank“ zpool you have been using sliced disks, this is unneeded but possible…

I am not that experienced with it but I guess you could issue
zpool replace tank c3t4d0s1 c3t0d0
(using the whole unsliced disk c3t0d0).
