Battered, bruised, but alive


2010 Scripting Games--I was there!

I only wish that I had the time to finish the rest of the games.  There is always next year I suppose.

NSX-T: Release associated invalid node ID from certificate

Image
Summary: Basically had an expiring certificate registered in NSX-T that was associated to a node_id that is no longer valid.  Long story short, there wasn't anything obvious in API to delete or disassociate a certificate from a node_id for 3.2.2.  Not sure how things got in this state, but annotating for future reference.  This may change in future revisions, so always check API for latest. Details: Effectively had a stale node associated w/ a certificate that was expiring.  Could not delete certificate until that node was disassociated from the certificate. To get certificate details and associated node_id's, you can use the following curl call (UI works too): curl -k -X GET -H "Content-Type: application/json" -u admin https://<manager ip>/api/v1/trust-management/certificates/<cert UUID> Above will return something like this: Below must be run from one of the manager nodes via elevation to root: ONLY RUN THIS IF YOU ARE ABSOLUTELY SURE OF WHAT YOU ARE DOI

Azure VMware Solution: NSX-T Active/Active T0 Edges...but

Image
Summary: Azure VMware Solution (AVS) delivers by default w/ a pair of redundant Large NSX-T Edge VM's each running a T0 in active/active mode.  So why is my traffic only going out one Edge VM? Short answer: The default T1 that is delivered w/ AVS is an active/passive T1 where you connect your workloads to.  So while it could technically take either T0, it's always going to go out the closest T0 to the active "SR" T1.  Where do the SR's live?  You guessed it, on the Edge VM's.  As you can imagine, this can lead to a bottleneck if you try to shove all your traffic through a single Edge VM. Simple Diagram: Longer answer with Options:

NSX-T: vCenter and NSX-T Inventory out of Sync (Hosts in vSphere not showing up in NSX-T)

Image
Summary: NSX-T loses synch w/ vCenter inventory, but statuses don't appear to show an issue.  Basically, you add a host to a vCenter cluster, NSX-T bits should start to automatically installing on new host.  Assuming you've created a Transport Node Profile and associated w/ the cluster.  The problem is that NSX-T doesn't see the new host and its link to the compute manager (vCenter) looks fine. Looks fine, Y U NO WORK!? So what's going on here?  This appears to affect NSX-T 2.5 and 2.5.1.  Cause is unknown. Workaround: Restart the cm-inventory service on each NSX-T mgmt/controller node using API or CLI. Details: If you were to query the status of the cm-inventory via API or CLI, you could query all 3 manager/controller nodes and get a status of running.  Even if the primary node associated w/ the VIP, if configured, is not necessarily in charge of inventory.  So you could restart the cm-inventory service till you are blue in the face and get nowhere be
