Abstract
Path components associated with I/O paths between another network component and a target system may be determined, and the health of target ports on such I/O paths may be determined. Failed I/O communications may be redirected based on the determined path components and the determined health of target ports. In response to a failed I/O communication, it may be determined which of the remaining I/O paths between the host system and the storage system has the least amount of associated path components in common with the failed I/O path, and the I/O communication may be redirected on such I/O path. The redirect I/O path also may be selected based on the health ranking of target ports of the I/O paths.
