This isn't a problem; the driver doesn't know that some commands return an
error status when they can't operate on the supplied parameters.

The 'soft write error' is just the controllers way of informing you that
its writing to a degraded volume.  In an ideal world the driver would trap
these soft error messages, rate limit them, and actually look up which
drive in the volume was bad and occasionally print an informative error
message with that info.
