Abstract
A first logical storage device associated with a first multi-path device is migrated to a second logical storage device associated with a second multi-path device. The migrating illustratively comprises suspending the first multi-path device, creating a proxy device for the first multi-path device, implementing a mirror device to provide a mirroring arrangement between the proxy device and the second multi-path device, inserting a request splitter between the first multi-path device and the mirror device, redirecting output of the first multi-path device to the request splitter, and resuming the first multi-path device. Responsive to synchronization of the proxy device and the second multi-path device via the mirroring arrangement, the migrating further comprises suspending the first multi-path device, removing the request splitter, the mirror device and the proxy device, redirecting output of the first multi-path device to the second logical storage device, and resuming the first multi-path device.
