After VirtuCache is installed, the LUN numbers as shown in VMware might be different than LUN numbers for the same LUN shown in the storage array GUI.

This is not a problem.

The reason for this is when VirtuCache claims these LUNs, VirtuCache assigns them LUN numbers, using VirtuCache pseudo-adapter, which can be different from the backend storage LUN number. The vSphere client shows the current active path LUN number which is assigned by VirtuCache.
