摘要
Provided are a computer program product, system, and method for populating a secondary cache with unmodified tracks in a primary cache when redirecting host access from a primary server to a secondary server. Host access to tracks is redirected from the primary server to the secondary server. Prior to the redirecting, updates to tracks in the primary storage were replicated to the secondary server. After the redirecting host access to the secondary server, host access is directed to the secondary server and the secondary storage. A secondary cache at the secondary server is populated with unmodified tracks in a primary cache at the primary server when the host access was redirected to the secondary server to make available to the host access redirected to the secondary server.
