NEW QUESTION # 34
An administrator installs a new NetApp ONTAP system in a customer's SAN environment. The customer wants to confirm that ALUA correctly changes the path states between Active/Optimized and Active/Nonoptimized.
Which event causes ALUA to change the path states?
- A. Shut down all FC LIFs on the HA partner node.
- B. Shut down one FC LIF.
- C. Disconnect one FC cable on the node hosting the LUN.
- D. Move the containing volume to the HA partner node.
Answer: A
Explanation:
ALUA (Asymmetric Logical Unit Access) is a protocol used in SAN environments to manage paths between a host and its storage. It enables the host to recognize and manage paths to the LUNs more efficiently by designating paths as either "Active/Optimized" or "Active/Nonoptimized". A significant event, such as shutting down all FC LIFs on the HA partner node, will trigger ALUA to change the pathstates. This action effectively causes the storage paths to transition from the HA partner node to the local node, switching the path states from Active/Nonoptimized to Active/Optimized on the paths that remain active.
