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 system for redirecting host access from a first server to a second server, wherein the first server manages access to a first storage and the second server manages access to a second storage, comprising:

• processing;
• and
• a computer readable storage medium having computer readable program code embodied that when executed performs operations, the operations comprising:
• performing a swap operation to redirect 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, wherein after the swap operation, the host I/O requests are directed to the second server;
• determining that the first server is available for data mirroring operations;
• determining data errors with respect to data in the first storage that experienced data errors;
• and
• instructing the second server 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.
