Symptoms

Health check fails with error:      
The appliance primary node cannot reach the secondary node through the native VLAN. This will prevent NAS services and Intra Cluster Data network from being fully functional. Ensure that the physical switches are configured properly. (Check_icd_node_reachability_failed)
 
Unable to ping between the Intra-Cluster data (ICD) interfaces from Node A to Node B, or the opposite way, or may be able to ping between ICD interfaces but still get the error:     
check_icd_node_reachability_failed

To test (ping) connectivity between the interfaces, find the Intra-Cluster data (ICD) IP address:     
  • Run ip addr and search for icd0.
  • Also, find it in PowerStore Manager by Settings > Networking > Network IPs > ICD. 
Note that ICD IP addresses are ipv6. Specify that in the ping command. 
 
Example:    
  • Node A: ping -6 -I icd0 <Node B's ICD ipv6 ip address> -c 3
  • Node B: ping -6 -I icd0 <Node A's ICD ipv6 ip address> -c 3

Cause

PowerStore NAS/iSCSI network is not configured correctly.

Resolution

If the PowerStore uses FibreChannel(FC) Only configuration, properly configured Ethernet ToR switch connections are required to continue. Refer to the Dell PowerStore T and Q Networking Guide for Initial Deployment for additional details.

If unable to ping as shown above, investigate the network to determine why. 

  • Check the switches to verify the bond/vLANS are correct.
  • Check that IPv6 is enabled on the necessary interfaces.

Refer to the Dell PowerStore T and Q Networking Guide for Initial Deployment to ensure that everything is set up correctly.

Lastly, upgrade to the latest PowerStoreOS in order to clear the error.
