Sent to direct the arbitrator to retest, without failure, the given resource allocations. The arbitrator must satisfy all allocation requests contained in the node list for the resource. The Configuration Manager subsequently sends either a ARB_SET_ALLOC or ARB_RELEASE_ALLOC message.
The arbitrator starts with the result of a previous ARB_TEST_ALLOC message. Without sorting the node list, the arbitrator makes a copy of the current allocation structure(s), releases all resources currently allocated to device nodes on the list, then attempts to satisfy the allocations from the previous ARB_TEST_ALLOC message. The arbitrator saves the successful allocations in the allocation data structure.
