NetApp NS0-516 Exam Dumps

Licensing Requirements: Both the primary and secondary systems must have the same premium features licensed to ensure compatibility and functionality for asynchronous mirroring.

System Discovery: Both systems need to be discovered by an Enterprise Management Window (EMW) or SANtricity Unified Manager to facilitate the setup and management of asynchronous mirroring.

Importance of Matching Features: Ensuring that both systems have the same features licensed avoids issues with mirroring operations that depend on specific functionalities being available on both ends.

Management Tools: Using EMW or SANtricity Unified Manager helps in configuring, monitoring, and managing the mirroring process effectively.

EF570 Systems: The EF570 supports multiple host protocols simultaneously, including NVMe.

Connection Issue: The controller on-board ports not connecting while HIC ports are working fine suggests a potential configuration issue.

SFP Mismatch: The most likely cause is that the on-board ports have the wrong Small Form-factor Pluggable (SFP) modules installed for NVMe protocol.

Solution: Ensure that the correct SFPs for NVMe protocol are installed in the on-board ports.

Understand ALB Requirements: Automatic Load Balancing (ALB) in NetApp E-Series systems requires compatible host multipath drivers and host types.

Check Host Multipath Driver:

Verify if the host multipath driver installed supports ALB.

Incompatibility with the multipath driver can prevent ALB from functioning correctly, causing imbalance.

Review Host Type Compatibility:

Ensure the host types used in the configuration support ALB.

Certain host types might not be compatible, resulting in ALB malfunction.

Potential Causes:

Host Multipath Driver (C): If the multipath driver does not support ALB, it won't distribute I/O efficiently across controllers.

Host Type (D): Incompatible host types can lead to issues with ALB implementation, causing imbalances.

Steps for Resolution:

Update or replace the host multipath driver with a version that supports ALB.

Reconfigure or update the host types to ensure compatibility with ALB.
