The management console server cannot find any statesave files on the storage unit that are ready to copy. One reason might be that a statesave operation has not completed, since a statesave operation might not complete immediately. After you copy a statesave file successfully from the storage unit to the management console, the statesave file on the storage unit has a status of Copied, and it cannot be copied again to the management console. Only statesave files with a status of Ready can be copied to the management console.
If you recently initiated a statesave operation, wait 30 minutes for the statesave operation to complete, and then copy the statesave file that has a status of Ready to the management console.
