Replace Local Manager Certificate

Geef een reactie

imageA customer send out the request to take a look at a few alarms they received in the NSX Manager console. The alarm they received was about a expiring certificate for local manager.

We did some investigating from the NSX Manager and it was clear that this was a self-signed (not linked to the company own PKI infrastructure) and it was in use. This last comment means we have to use the Application Programing Interface (API) to tell NSX to use the new certificate.

Since this is a production environment we don’t do anything before we have verified that a recent backup of the NSX database is available. Please take note that a VMware snapshot is not supported the restore a NSX Manager Cluster. It is  best practice to have a scheduled NSX Manager backup schedule. Before we start working on the environment we create a manual backup of the NSX database.

Unable to delete a segment in NSX because of an orphaned logical port

imageFor one of our customers all NSX related questions are routed to me (pun intended). I received a customer ticket stating that they where not able to remove an unused NSX created port group although it is not in use while observing from vCenter.

After some investigating within NSX it was clear that this issues was caused by an orphaned logical port. NSX allows you to do allot of the config from the UI, but for some actions it is required to turn to the application programming interface (API). NSX provides a programmatic API to automate management activities. The API follows a resource-oriented architecture by using JSON object encoding. Clients interact with the management plane by using RESTful web service calls over HTTPS.
