A customer has recently decommissioned a server and has decided to reuse it for another purpose in a new data center. Due to a high priority business request, the server is moved over and the operating system has not been reinstalled.
As the storage administrator, you attach the server via Fibre Channel to a new set of switches and a new CLARiiON. After attaching the Fibre Channel cables and performing the zoning, the host is not seen in the Connectivity Status screen on the new CLARiiON. A double check of the configuration reveals the zoning is correct and is not the problem.
What is the cause of the problem?
Answer : B
