Drivers trying to do IO solely on paths which are online but some way defective may lack the information to do proper error handling. There is no reason to allow the usage of known to be broken paths. Thus restrict the paths a ccw driver can use for IO to a subset of the paths cio found usable (this also excludes offline paths).
