    摘要： Provided are a method, system, and article of manufacture for managing the copying of writes from primary storages to secondary storages across different networks. Information is maintained on a first group of at least one primary storage, at least one primary device managing Input/Output (I/O) access to the at least one primary storage, and at least one corresponding secondary storage to which writes to the at least one primary storage are copied and a second group of at least one primary storage, at least one primary device managing Input/Output (I/O) access to the at least one primary storage, and at least one corresponding secondary storage to which writes to the at least one primary storage are copied. A failure notification is received from one of the primary devices in the first or second group of a failure to copy a write from the primary device to the secondary device. A freeze command is issued over a first network, using a first network protocol, to the at least one primary device in the first group to stop copying writes to the corresponding at least one secondary device. A freeze command is issued over a second network, using a second network protocol, to the at least one primary device in the second group to stop copying writes to the corresponding at least one secondary device.

    摘要： Provided are a method, system, and program for using a heartbeat signal to maintain data consistency for writes to source storage copied to target storage. A copy relationship associates a source storage and target storage pair, wherein writes received at the source storage are transferred to the target storage. A determination is made whether a signal has been received from a system within a receive signal interval. A freeze operation is initiated to cease receiving writes at the source storage from an application in response to determining that the signal has not been received within the receive signal interval. A thaw operation is initiated to continue receiving write operations at the source storage from applications after a lapse of a freeze timeout in response to the freeze operation, wherein after the thaw operation, received writes completed at the source storage are not transferred to the target storage.

    摘要： Provided are a method, system, and article of manufacture for copying writes from primary storages to secondary storages across different networks. A failure notification is communicated, using a first network protocol, from a primary device in a first group of at least one primary device and at least one corresponding primary storage managed by the at least one primary device to a control system in response to the primary device determining that a write to the primary storage cannot be copied to a corresponding secondary storage. A failure notification is communicated, using a second network protocol, from a primary device in a second group of at least one primary device and at least one corresponding primary storage managed by the at least one primary device to the control system in response to the primary device determining that a write to the corresponding primary storage cannot be copied to a corresponding secondary storage. A freeze command is received, from the control system using the first network protocol at the at least one primary device in the first group. A freeze command is received, from the control system using the second network protocol at the at least one primary device in the second group. The copying of writes from the primary storages in the first and second groups to the corresponding secondary storages is suspended in response to receiving the freeze commands.

    摘要： Disclosed is a system for maintaining consistency of data across storage devices. A cut-off time value is provided to the system. The system then obtains information on data writes to a first storage device, including information on time stamp values associated with the data writes indicating an order of the data writes to the first storage device. At least one group of data writes having time stamp values earlier in time than the cut-off time value is then formed. The system then transfers the data writes in the groups to a second storage device for storage therein.

    摘要： Disclosed is a system for isolating errors in a remote copy system. A first controller writes data to a volume in a first direct access storage device (DASD) and maintains a copy of the data in a cache. The first controller transfers the data in the cache to a host system via a first communication line. The host system then transfers the data transferred from the first controller to a second controller via a second communication line. The second controller writes the data transferred from the host system to a volume in a second DASD. A volume pair is comprised of a volume in the first DASD and a volume in the second DASD, wherein for each volume pair, the second DASD volume backs-up data stored in the first DASD volume. If an error related to a volume pair is detected, then the operation of transferring the data in the cache for the volume pair related to the error to the second controller via the host system is suspended. Information on the detected error is written to a first data set. Further, after the transfer of data from the cache is suspended, information on a location of data written to the first DASD volume in the volume pair related to the error is written to a second data set. The information in the second data set is used to determine the location of data written to the first DASD volume of the volume pair related to the error while the transfer of the data to the second DASD volume of the volume pair is suspended. Upon correction of the error related to the volume pair, data written to the first DASD volume at the determined location is transferred to the second storage controller via the host system for storage in the second DASD volume of the volume pair.
