Symptoms

System Health may display failure of the symmetric ICM connection check with one of the following messages:

  • "ICM connection: Nodea: DOWN, nodeb: UP (KB#000203115)"
  • "ICM connection: nodea: UP, nodeb: DOWN (KB#000203115)"


This health check may occur in one of the following scenarios:

  • Running a System Check using PowerStore Manager (UI) with the Run System Check option
  • Running a System Check using PowerStore Manager (UI) with the Run Upgrade Extensions option (PowerStoreOS 2.1.x only)

  • Running the System Health Service Script (svc_health_check) using an SSH connection:
[SVC:root@ABCDEF-A ~]$ svc_health_check run -rhc symmetric_icm_connection -p Upgrade_Extensions
Name                   Location Status     Description
Symmetric ICM Connec.. node_b   FAILED     ICM connection: nodea: DOWN, nodeb:
                                           UP (KB#000203115)
When this issue exists, the NDU fails.  

 
 

Cause

The above message indicates that one node has an ICM connection while the other node does not have an ICM connection. 

Resolution

Do not proceed with NDU or maintenance operations if this condition is detected.

To resolve this issue, ensure that all ports and cables are connected properly, and all related alerts are resolved. If the issue persists, contact technical support for assistance. Reference KB #000203115 for expedited attention and resolution.
