    摘要： Provided are a method, system, and program for maintaining consistency when mirroring data using different copy technologies. Update groups having updates to primary storage locations are formed using a first copy technology. The updates in the update groups are copied to secondary storage locations. Update groups having updates to primary storage locations are formed using a second copy technology, wherein the updates in the update groups are copied to secondary storage locations. Indication is made in a data structure of a time of an update in response to including the update in one of the update groups formed using the first copy technology. Indication is also made in the data structure of a time of the update group formed using the second copy technology.

    摘要： Provided are a method, system, and program for remote copying of updates to primary and secondary storage locations subject to a copy relationship. A first copy relationship is established between first and second storage locations in a first storage system and second storage system, respectively, wherein updates to the first storage locations are copied to the second storage locations. A second copy relationship is established between the first storage locations in the first copy relationship and third storage locations in a third storage system, wherein updates to the first storage locations are indicated in a first bitmap. A suspended third copy relationship is established between the second storage locations in the first copy relationship and the third storage locations, wherein updates to the second storage locations are indicated in a second bitmap. Updates are copied from the first or second storage locations to the third storage locations, wherein the first or second bitmap is capable of being used to determine updates for the first or second storage locations to copy to the third storage locations.

    摘要： Provided are a method, system and program from managing failures in a mirrored system. A copy relationship between primary and secondary storage locations, wherein updates to the primary storage locations are copied to the secondary storage locations. A failure is detected preventing an application from writing updates to the primary storage locations. A failure message is received for the application in response to detecting the failure, wherein the failure message is not provided to the application. The copying of updates to the primary storage locations to the secondary storage locations is suspended. The failure message is provided to the application in response to suspending the copying.

    摘要： Provided are a method, system and article of manufacture for switching. An indication is received of a failure of a primary storage subsystem at a switch, wherein the switch couples a host to the primary storage subsystem and a secondary storage subsystem. Subsequently, a command received from the host at the switch is directed to the secondary storage subsystem for completion.

    摘要： A DC-DC converter having a transformer, a reactance coil and a controllable switch for turning a DC supply voltage on and off. The contact gap of a switching transistor is set at a reference potential at a connecting tap between a primary winding and a secondary winding of the reactance coil, which is connected like a transformer with a certain transformation ratio. The anode-cathode segment of a diode and an output capacitor are set at reference potentials in series with the secondary winding of the reactance coil, with the output voltage for a load being applied across the output capacitor. The DC supply voltage is supplied to the primary winding of the reactance coil over an inductance arrangement, and a capacitance arrangement is arranged in parallel with the contact gap of the switching transistor so that a series resonant circuit, which is operative in the turn-on and turn-off phases of the switching transistor, is provided by the inductance arrangement and the capacitance arrangement.
