At least one processing device is configured to control delivery of input-output (IO) operations from a host device to a storage system over selected ones of a plurality of paths through a network. The at least one processing device is further configured to designate one or more of the paths as being associated with a link performance issue, to temporarily suspend utilization of the one or more designated paths for delivery of IO operations from the host device to the storage system, to detect a configuration change that is indicative of potential resolution of the link performance issue, and to resume utilization of the one or more designated paths responsive to the detected configuration change. The at least one processing device illustratively comprises a multi-path input-output (MPIO) driver of the host device.

Described are a system and method for providing data protection. A storage management system in communication with first and second storage arrays is configured to implement a data protection procedure for protecting data stored in the first storage array using the second storage array. An environmental information processor receives information related to an event that can threaten the data stored in the first storage array and, based on the received information, issues a command to the storage management system. The command causes the storage management system to initiate the data protection procedure as a precautionary action for protecting the data stored at the first storage array.
