Drive configuration commands result in an excessive flood of messages on the
console.

The mpt version 1 API that is used by
.Nm
and
.Xr mpt 4
doesn't support volumes above two terabytes.
This is a limitation of the API.
If you are using this adapter with volumes larger than two terabytes, use the adapter in JBOD mode.

.Xr zfs 1M
