StorageFCAdapterFault_Alert - Resolution Guide

Last Updated:

Applies to

  • ONTAP 9
  • MetroCluster Fibre Channel
  • StorageFCAdapterFault_Alert


StorageFCAdapterFault_Alerts are triggered on FC MetroCluster systems when an initiator link is detected at being down. This alert can have multiple causes.

  • Call home alert:

[mgwd:]: Call home for Health Monitor process nchm: StorageFCAdapterFault_Alert [100000109bxxxxxx].

  • The MetroCluster_Node subsystem health reports degraded:

cluster::> system health subsystem show
Subsystem         Health
----------------- ------------------
SAS-connect       ok
Environment       ok
Memory            ok
Service-Processor ok
Switch-Health     ok
CIFS-NDO          ok
Motherboard       ok
IO                ok
MetroCluster      ok
MetroCluster_Node degraded

FHM-Bridge        ok
13 entries were displayed.

  • Health alert reports the adapter(s) at fault:

cluster::> system health alert show
               Node: node-01
           Resource: 4d
           Severity: Major
    Indication Time: Sat Aug 15 13:05:58 2020
           Suppress: false
        Acknowledge: false
     Probable Cause: FC initiator adapter 4d is at fault.
    Possible Effect: Resiliency of backend storage is compromised.
 Corrective Actions: 1. Ensure that the FC initiator link has not been tampered with.
                     2. Verify the operational status of the FC initiator
                     adapter by using the command "system node run -node
                     local -command storage show adapter".

  • Event logs report:

::> event log show

[slifc_intrd:]: Link break detected on Fibre Channel adapter 4d.
[slifc_timeout_3:]: Could not recover link on Fibre Channel adapter 4d after 30 seconds. Taking the adapter offline.
[nchmd: hm.alert.raised:alert]: Alert Id = StorageFCAdapterFault_Alert , Alerting Resource = 100000109bxxxxxx raised by monitor node-connect
