Associating Node GUID with the OVC

[TDW1]

I am having some network issues and one of the troubleshooting steps is to run "egrep -i "faulty|suspected" $SVTLOG" from an OVC. I see some entries where the State = SUSPECTED.  It shows the Node GUID but how do I associated it with the OmniStack host?

Hi @TDW1 

I see that you are unsure how to link the Node GUID to a specific OmniStack host after running "egrep -i "faulty|suspected" $SVTLOG".

Note that the Host ID is a GUID and not an IP address or Hostname of the node. While this may appear confusing to the end user, this is the actual GUID of the HPE SimpliVity node. Mapping the GUID to the hostname or IP address of the node is not possible through the GUI.

You may use the command "dsv-balance-show --shownodeip" to display the IP of the OmniStack host instead of the GUID which makes it easier for users to identify a node.

For more details on this, you may refer to the below links:

Hello @TDW1 

You could probably use the command "svt-federation-show --o xml" to see the node GUID and its correspoding OVC IP. 

Hope it helps.
