In a partitioned db2 environment using 7.2 EEE, what happens if we do not have cluster environment and one of the nodes goes down?

Does the whole environment become useless or is there a way that we can still retrive the existing data on the running nodes. Because in my setup of partitioned db2 using 2 systems, even if node 1 goes down, I am unable to retrive data that is local to node 0 (instance owning partitioned database server).

Your answer would be highly appreciated.

Thanking You,
