Question 1
Multiple answersAn administrator is troubleshooting intermittent high latency on a critical iSCSI LUN presented from an ONTAP 9.8 cluster to a VMware ESXi environment. The latency spikes occur during peak business hours. The administrator needs to investigate the issue from the storage array's perspective using the ONTAP CLI to gather real-time and historical performance data for the specific LUN and its associated network paths. Which TWO commands are most effective for this initial investigation? (Select TWO)
Answer and explanation
Correct answers: B, C
The lun statistics show command provides detailed performance metrics specifically for LUNs, including IOPS, throughput, and latency. This is essential for determining if the latency is originating at the LUN level itself.
The network port show command is crucial for checking the health, speed, and duplex settings of the physical ports handling iSCSI traffic. It can also reveal errors, such as CRC errors or discards, that would directly contribute to network-induced latency.
