- Clustered ONTAP 8.3.1P1+
- ONTAP 9
ONTAP uses Cluster Session Manager (CSM) communication channels to exchange information between nodes in a cluster.
The following issues are seen:
- Connection failure
- Application triggering
- Long idleness
CSM session failures that result from application triggers or long idle sessions pose no risk to the system.
In contrast, connection-related failures should be investigated, and may represent a larger whole issue.
As all three scenarios are presented as
csm.sessionFailed:warnings, we must investigate to determine the root cause of the warning.
