  • Autonomic recovery of PPRC errors detected by PPRC peer
    Patent number: 7454655
    Abstract: A method for initiating a data storage facility recovery process in a data processing system having a first peer data storage facility and a second peer data storage facility communicating with the first peer data storage facility by a communication link. The method of initiating a recovery process is invoked by one peer data storage facility upon another peer data storage facility operating under a peer to peer remote copy (PPRC) protocol. Data copied from a first peer data storage facility to a second peer data storage facility is monitored for errors. Upon detection of an error by one peer data storage facility, recovery and data collection operations are initiated on the other peer data storage facility. Preferably, the initiation of recovery and data collection operations occurs out of band, over a second communication link between the peer data storage facilities.

  • Method and apparatus for determining using least recently used protocol if one or more computer files should be written to one or more information storage media and synchronously providing one or more computer files between first and storage devices
    Patent number: 7240080
    Abstract: A method to copy information to two data storage devices. The method provides a first data storage device and a second data storage device, where the first data storage device is capable of communicating with the second data storage device. The method provides first information and a write command to the first data storage device at a first time. The method determines if the write command comprises a synchronous copy attribute. If the write command comprises a synchronous copy attribute, then the method synchronously provides the first information to the second data storage device. Alternatively, if the write command does not comprise a synchronous copy attribute, then the method provides the first information to the second data storage device at a second time, where that second time is later than the first time.
