Upon receiving a primarysecondary switching command from a secondary host system, a secondary storage control device interrogates a primary storage control device as to whether or not yet to be transferred data that has not been remote copied from the primary storage control device to the secondary storage control device is present. The invention further concerns a product obtainable by the coating method. The flexible sealing finger is received within a sealing chamber formed as part of the rim. The amplifier amplifies the difference between the reference voltage and the first tuning voltage. The object can be serialized at a sender computer process and transported to a receiver computer process, where the serialized data object is received and deserialized to retrieve the hashtable.
