After deleting a LUN, an administrator notices that the space does not show as available. What needs to be done to reclaim the space?
After deleting a LUN, if the space does not show as available, performing space reclamation is necessary. Space reclamation involves identifying and reclaiming unused space on the storage system, making it available for new data. This process ensures that the deleted LUN's space is properly freed up and reflected in the available storage capacity.
For more details, refer to:
NetApp Documentation on Space Reclamation
NetApp Community on Free Space Reclamation
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 IP

During an iSCSI deployment, the customer requests a change of front-end network connections on the NetApp ONTAP cluster from twinax cables to fiber-optic cables.
Which two NetApp tools would an administrator use to verify the supported port speeds and transceivers? (Choose two.)
During an iSCSI deployment, if a customer requests a change from twinax cables to fiber-optic cables, two NetApp tools can be used to verify the supported port speeds and transceivers:
Hardware Universe (HWU): This tool is essential for determining the supported transceivers and port speeds for NetApp hardware. It provides detailed information on hardware compatibility, including supported transceivers, cables, and port speeds, which helps ensure that the selected components are compatible with the NetApp storage system.
Interoperability Matrix Tool (IMT): The IMT provides comprehensive compatibility information between NetApp products and third-party components. It includes details on supported transceivers and port speeds, ensuring that any changes made to the network connections are supported and will function correctly in the given configuration.
For more detailed information, you can refer to the following resources:
NetApp Hardware Universe (NetApp).
NetApp Interoperability Matrix Tool (NetApp).
When using tagged VLANs on Cisco Nexus switches for NVMe over TCP, which two changes must be made to enable jumbo frames? (Choose two.)
For enabling jumbo frames on Cisco Nexus switches for NVMe over TCP with tagged VLANs, the following changes are required:
Modify the Cisco Nexus switches to use an MTU of 9216: Setting the MTU to 9216 ensures that the network can handle jumbo frames, reducing the number of packets needed for large data transfers and thus improving performance.
Modify the appropriate broadcast domain in NetApp ONTAP software to use an MTU of 9216: This setting must match the network configuration to ensure end-to-end support for jumbo frames, which is essential for optimizing performance in NVMe over TCP environments.
For additional information, refer to:
NetApp Documentation on NVMe over TCP
Cisco Documentation on Jumbo Frames
A customer wants to enable CHAP authentication on their iSCSI sessions.
Which command should be used to set up the appropriate security policies and passwords?
To enable CHAP (Challenge-Handshake Authentication Protocol) authentication on iSCSI sessions, the command vserver iscsi security create should be used. This command sets up the necessary security policies and passwords required for CHAP authentication, ensuring secure access to iSCSI targets.
For more details, refer to:
NetApp Documentation on iSCSI Configuration (NetApp).
