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. Signed-off-by: Martin Wilck Acked-by: Lee Duncan Signed-off-by: Martin K.
