4. A company has requested an independent consultant to develop and implement a security model for the

run.
The customer asks for a check to see if their data is still available from CLARiiON storage as they cannot find
their LUNs. The CLARiiON SP event logs show the data in the exhibit. Which method can the customer use to
correct the problem?
