StorageFCAdapterFault_Alert - Resolution Guide
Applies to
- ONTAP 9
- MetroCluster Fibre Channel
- StorageFCAdapterFault_Alert
Description
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: callhome.hm.alert.major:alert]: Call home for Health Monitor process nchm: StorageFCAdapterFault_Alert [100000109bxxxxxx].

- 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: fci.link.break:error]: Link break detected on Fibre Channel adapter 4d.
[slifc_timeout_3: fci.link.error:error]: Could not recover link on Fibre Channel adapter 4d after 30 seconds. Taking the adapter offline.
