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?
Answer(s): A
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 path states. 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.For more information, you can refer to:NetApp Community Discussion on ALUANetApp Documentation on ALUA
An engineer Is implementing a data migration scenario for a customer who has multiple FC LUNs across multiple third-party SAN arrays. The engineer wants to use Foreign LUN Import (FLI) for the migration.What is a requirement on the destination NetApp ONTAP cluster for FLI?
Answer(s): D
When using Foreign LUN Import (FLI) for migrating LUNs from third-party SAN arrays to a NetApp ONTAP system, one of the requirements is to have at least one Fibre Channel (FC) port configured in target mode on the destination NetApp ONTAP cluster. This configuration is necessary to facilitate the migration process as the target mode port will accept and manage incoming data from the source SAN arrays.For additional details, refer to:NetApp Documentation on FLI
What connectivity Is required between NetApp ONTAP clusters in order to configure SnapMirror active sync across two data centers for FC?
Answer(s): C
To configure SnapMirror active sync across two data centers using FC (Fibre Channel), the required connectivity between NetApp ONTAP clusters is cluster peering. Cluster peering involves establishing a trust relationship between the clusters, allowing them to replicate data seamlessly. This setup ensures that data synchronization and disaster recovery processes are effective and reliable.For more detailed information, you can check:NetApp Documentation on SnapMirror and Cluster Peering
What is the minimum number of rack units that are required on each site for a NetApp AFF All San Array (ASA) A800 MetroCluster IP configuration with 72 disks per site and Cisco N9K-C9336C-FX2 backend switches?
For a NetApp AFF All SAN Array (ASA) A800 MetroCluster IP configuration with 72 disks per site and Cisco N9K-C9336C-FX2 backend switches, the minimum number of rack units required on each site is 16 RU. This includes space for the controllers, disk shelves, and the necessary network switches. This configuration ensures that all components are properly accommodated and operational within the specified rack space.For detailed information on the rack unit requirements and MetroCluster IP configurations, refer to:NetApp Documentation on MetroCluster IPMetroCluster IP Solution Architecture
