摘要:
A method may include establishing, by a MPIO driver of a host information handling system, an I/O path between the host information handling system and the source storage array as an active I/O path and a path between the host and the target storage array as a passive I/O path. The method may also include performing a snapshot-based iterative replication between the source storage array and the target storage array, wherein successive iterations of the snapshot-based iterative replication comprise I/O to the source storage array occurring during an immediately previous iteration of the snapshot-based iterative replication. The method may further include, upon completion of the snapshot-based iterative replication, establishing, by the MPIO, the I/O path between the host and the source storage array as a passive I/O path and the path between the host and the target storage array as the active I/O path.
