PowerVault MD3000 environment. The SAS5EADD utility is capable of reassigning a
unique World Wide Name (WWN) on the SAS 5/E Adapter controller. Two scenarios
for running the utility are outlined below. Scenario 1 covers the situation in which the
PowerVault MD3000 has not yet been configured and is awaiting deployment.
Scenario 2 covers the situation in which the PowerVault MD3000 system has already
been configured and is in use.
