Corrective Action

Make sure that the local and remote storage systems are correctly connected via cable to each other.

Make sure that you entered the correct remote storage system S/N (serial number) and path parameters (e.g., local storage system port, remote storage system port, and controller ID).

Make sure that the topology settings of the local and remote storage system ports are correct.

Make sure that the remote storage system is powered on, and that NVS and cache are fully functional.

Make sure that network relay devices (including cables, connectors, ESCDs, extender devices, communication lines, and all other devices connected to the extenders) are properly configured and functional. After that, delete the failed path. You may need to change the minimum paths setting or delete the remote storage system in order to delete the path. After deletion finishes, add the path or the remote storage system by using the Add Path window or the Add DKC window.
