NBU 6.0 MP4
4-nodes Veritas cluster (3 active, 1 fail-over node)
Exchange 2003

I can backup the 3 virtual instance that's on the node 1,2,3; But whenever
I failover to node 4, if failed with error 69. This happened on any of the
3 virtual exchange instance that I tried to failover to node 4.
Any help would be approciated.
