PowerStore: System Health Check fails for "Unable to perform health check due to communication error"

After installing the PowerStore-health_check-4.0.1.0-2416779-retail.tgz.bin package, the system health check fails multiple checks with error "Unable to perform health check due to communication error."

UI details may also show that the System Health Check Fireman command failed (0xE0F010200004)

Due to CPU0 high load, Control Path (CP) and other management functions may also be impacted. 

The service cyc.bsc_status_check_service.service is not restarted during the installation of the PowerStore-health_check-4.0.1.0-2416779-retail.tgz.bin package. This results in CPU0 high load which causes system health check to fail multiple checks with error "Unable to perform health check due to communication error" due to exceeding timeout values.

Workaround:

Rebooting each node one at a time using the svc_node reboot command will work around the issue and allow the system health check to pass. It is recommended to reboot the peer (non-primary) node first and the primary node second. It is important to verify the first node is fully up and functional before rebooting the second node. The svc_diag list --basic command can be used to identify which node is the primary.
 

===================== Nodes ======================

id: N1

name: WK-A1234-appliance-1-node-A

slot: 0

appliance_id: A1
is_primary: False
 
 
id: N2

name: WK-A1234-appliance-1-node-B

slot: 1

appliance_id: A1
is_primary: True

Dell Technical Support can issue a root level command to restart the service cyc.bsc_status_check_service.service if rebooting the nodes one at a time is not a viable workaround. Escalate to Dell Technical Support and reference this knowledge article for assistance.

Fix:

This issue is fixed in the PowerStore-health_check-4.0.1.0-2424376-retail.tgz.bin package.
