An administrator runs the vserver nvme namespace convert-from-iun command on a NetApp ASA cluster to increase host performance.
What is modified by the convert command?
The vserver nvme namespace convert-from-lun command in a NetApp ASA cluster is used to convert a LUN to an NVMe namespace to increase host performance. This process involves modifying the metadata of the storage object to make it compatible with the NVMe protocol, allowing for faster access and reduced latency
An administrator configured an SVM with LUNs with two WWPNs per node. The administrator accidentally created a WWPN on node1 that needs to move to node2. The SAN hosts use ALUA.
Based on this requirement, what must be taken offline to correct the situation?
To move a WWPN from node1 to node2 in a NetApp ONTAP SAN environment where ALUA is used, you must take the Logical Interface (LIF) offline. Modifying LIFs involves changing their assignment between nodes, which requires them to be temporarily offline. This ensures that the path states are correctly updated without causing disruption to the SAN hosts.
For more details, see:
NetApp Community on Moving LIFs
NetApp Documentation on SAN LIFs
Which two NetApp features provide synchronous data replication between two sites for SAN workloads with automatic failover in case of a site disaster? (Choose two.)
For synchronous data replication between two sites with automatic failover in case of a site disaster for SAN workloads, the two NetApp features that provide these capabilities are SnapMirror Synchronous and MetroCluster IP.
SnapMirror Synchronous: This feature provides volume-granular, synchronous replication with zero RPO (Recovery Point Objective), ensuring that data is mirrored in real-time to a secondary site. This setup supports automatic failover, maintaining data availability even during site failures
MetroCluster IP: This solution provides synchronous replication and combines high availability and disaster recovery capabilities. MetroCluster IP uses IP networking to extend the distance over which replication can occur and supports automatic failover and failback, making it suitable for critical SAN workloads
An administrator runs the vserver nvme namespace convert-from-iun command on a NetApp ASA cluster to increase host performance.
What is modified by the convert command?
The vserver nvme namespace convert-from-lun command in a NetApp ASA cluster is used to convert a LUN to an NVMe namespace to increase host performance. This process involves modifying the metadata of the storage object to make it compatible with the NVMe protocol, allowing for faster access and reduced latency
Which NetApp feature presents LUNs only within the HA pair?
Selective LUN Mapping (SLM) is the feature that presents LUNs only within the HA pair. SLM allows administrators to control which LUNs are visible to which hosts, ensuring that LUNs are only accessible through the designated HA pair, thus improving security and manageability.
