    • <Event ID> | <DATE> | <TIME> | Memory | Correctable ECC (@DIMM<ID>(CPU<#>)) | Asserted
  • NetApp SolidFire ActiveIQ and cluster UI shows that all block and metadata services of the node are unresponsive shortly after the SEL log entry:
    • unresponsiveService - A block service is not responding. (This alert will be shown for each block drive)
    • unresponsiveService - A metadata service is not responding.
  • Unhealthy service alerts are shown  shortly after the unresponsive services alerts:
    • blockServiceUnhealthy - A block service is unhealthy and SolidFire is attempting to migrate data away from it.
