REGISTER AND IGNORE EXISTING KEY service action or REGISTER AND MOVE
service action is attempted, but there are insufficient device server
resources to complete the operation, then the command shall be terminated
with CHECK CONDITION status, with the sense key set to ILLEGAL REQUEST,and
the additonal sense code set to INSUFFICIENT REGISTRATION RESOURCES.
