Abstract: Provided are a computer program product, system, and method for managing health conditions to determine when to restart replication after a swap triggered by a storage health event. A determination is made of a health condition with respect to access to a first storage that triggers a swap operation. The swap operation redirects host Input/Output (I/O) requests to data from a first server to a second server in response to determining the health condition. After the swap operation the I/O requests are directed to the second server and a second storage. The second server is instructed to mirror data in the second storage to the first server to store in the first storage in response to determining that the health condition is resolved.

Abstract: Provided are a computer program product, system, and method for after swapping from a first storage to a second storage, mirroring data from the second storage to the first storage for data in the first storage that experienced data errors. A swap operation redirects host Input/Output (I/O) requests to data from the first server to the second server in response to a health condition at the first server. A determination is made of data errors with respect to data in the first storage that experienced data errors. The second server is instructed to mirror data in the second storage to the first server including data for the data in the first storage that experienced the data errors to store in the first storage in response to determining that the first server is available for the data mirroring operations.

Abstract: A method for improving system availability in data replication environments is disclosed herein. In one embodiment, such a method includes detecting a suspend trigger, where the suspend trigger indicates that data mirroring between a primary volume and a secondary volume has been suspended. The method further detects a swap trigger some time after detecting the suspend trigger. The swap trigger indicates that I/O directed to the primary volume has failed. In the event the swap trigger is detected within a specified amount of time after detecting the suspend trigger, the method redirects I/O from the primary volume to the secondary volume. A corresponding system and computer program product are also disclosed.
