摘要： Repositioning within an input/output device is accomplished without any knowledge of where the input/output device is currently positioned. The input/output device is repositioned to a predetermined position, in order for a program to be retried. The predetermined position is determined from a previously executed program. The previously executed program is scanned looking for commands. For each command found, a position identifier is adjusted based upon the type of command. When the scan and adjustments are complete, the position identifier represents the predetermined position used for repositioning the input/output device.

摘要： Provided are a computer program product, system, and method for synchronous mode replication to multiple clusters receiving a write to a volume from a host. A received write is cached in a memory. A determination is made of a replication rule indicating one of a plurality of replication modes for a first cluster and a second cluster used for replication for the write, wherein one of the replication modes comprises a synchronous mode. A determination is made that the replication rule indicates a synchronous mode for the first and the second clusters. The write is transmitted from the memory to the first cluster to store in a first non-volatile storage of the first cluster and to the second cluster to store in a second non-volatile storage in response to determining that the replication rule indicates the synchronous mode.
