ASC 0x27 is "WRITE PROTECTED". This error code is returned e.g.
by Fujitsu ETERNUS systems under certain conditions for
WRITE SAME 16 commands with UNMAP bit set. It should not be
treated as a path error. In general, it makes sense to assume
that being write protected is a target rather than a path
property.
