Topic #: 2
An administrator is configuring an iSCSI LUN for use on a CVO HA instance in AWS. Before the LUN goes into production, the administrator needs to do failover testing for host access.
Which type of IP address must the administrator use?
When configuring an iSCSI LUN for use on a Cloud Volumes ONTAP (CVO) HA instance in AWS, especially during failover testing for host access, the administrator must use a Floating IP address. Here's why:
Purpose of Floating IP: In an HA configuration, the Floating IP provides a consistent network address that remains accessible, even when the service fails over from one node to another. This ensures that any connections to the iSCSI LUN remain uninterrupted during node failures.
Configuration and Testing: By using a Floating IP, the administrator ensures that the storage clients or hosts always connect to the active node, maintaining access to the iSCSI LUN even during the failover processes.
High Availability Setup: During failover testing, the Floating IP facilitates the seamless transition of network services from one node to another without requiring configuration changes on the client side or re-establishing connectivity.
For more details on configuring Floating IPs in a NetApp CVO HA setup in AWS, you can refer to the NetApp documentation on HA configurations: NetApp High Availability Guide.
