PowerStore: System Health Check fails for "BBU Sensor Check node_x FAILED Mismatched part number detected on node X (KB#000196197)"

The System Health Check (SHC) test of "bbu_sensor_check" fails on both Nodes, reporting "Mismatched part number detected"
 

[SVC:service@XXXXXXX-A user]$ svc_health_check run

    
The user interface Hardware Component Internal View shows BBU Healthy for both nodes, but the BBU Part Number is different on each node.





svc_diag hardware check on both Node A and Node B show BBUs are OK.
Run the command against both nodes.

$ svc_diag list --hardware --sub_options fault_status

 
svc_diag shows different part numbers for BBU 0 and 1.
Run the command against both nodes.

$ svc_diag list --hardware --sub_options inventory |grep -A5 Battery

 

There is a problem in the latest system health check thin packages for PowerStoreOS 2.1.x and 3.x which incorrectly checks the BBU part number between the two nodes and fails if they are not the same.

All System Health Check packages since PowerStore-health_check-2.1.1.1-1736451 for PowerStoreOS 2.1.X are affected.
All System Health Check packages since PowerStore-health_check-3.0.0.0-1781415 for PowerStoreOS 3.X are affected.

PowerStore supports 11 different BBU part numbers and the system health check expects the PN of both BBUs to be the same, which may not be the case. Any of the below part numbers are valid and supported.
078-000-168-02
078-000-177-02
078-000-192-00
078-000-195-03
078-000-211-01
088-000-168-02
088-000-177-02
088-000-192-00
088-000-195-03
088-000-211-00
088-000-211-01

If the BBUs are in a healthy state and the only error produced by running the system health check that thin package is "BBU Sensor Check node_x FAILED Mismatched part number detected on node X (KB#000196197)," the error can be ignored and the NDU can be started.

This is fixed in a new release of the system health check thin packages under development.
