Abstract
Triggering a storage system swap event based on device error impact includes monitoring for input/output (I/O) errors on each of a plurality of storage devices of a first storage system. A criticality attribute of each of the plurality of storage devices is determined. A device score is calculated for each of the plurality of storage devices based on a number of I/O errors detected for the storage device. A swap score value for the first storage system is calculated based on the criticality attribute of each of the plurality of storage devices and the device score for each of the plurality of storage devices. Whether to either perform or bypass a storage swap event is determined based on the swap score value, wherein the storage swap event includes swapping between usage of the first storage system and a second storage system by a computing system.
