LUN numbers shown in VMware are different from backend storage LUN numbers
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.
