What should you do in this situation?

  • A Replace disks 6b.34 and 6a.19.
  • B Add disks to the aggregate to bring down the average utilization.
  • C Replace disk 6b.39.
  • D Reseat shelf module B.
Explanation

Disk 6b.39 is the outlier at 100% utilization and has exceptionally high read latency, indicating a slow or failing disk that is consuming its available service time. Replacing that disk addresses the bottleneck; adding aggregate capacity or replacing unrelated disks would not correct the isolated latency condition.
