DASD path verification requires the usage of sleep_on_immediatly to ensure that no other I/O request is blocking the recovery of disconnected devices. But two concurrent path verification workers for the same device may kill each others requests due to the usage of the immediate sleep_on function. This may lead to unsuccessful path verifications. Prevent that two parallel path verification workers conflict with each other by implementing a device flag signalling a already running worker.
