secondary nsx manager unavailable from vCenter after a disk failure in the secondary SDDC

Jump to solution

We had a disk failure in our 2nd SDDC which caused errors with vSAN and numerous VM instances.

After the vSAN had been restored, the secondary nsx Manager no longer showed from vCenter.  FYI, we have a stretched nsx environment across two SDDC.

The secondary nsx manager is up and have reachability to the primary nsx manager as well as to the vCenters, and I tried to add the 2ndary nsx manager again, but it failed because the 2nd nsx manager already exists. 

What will be the best way to restore the 2ndary NSX Manager?

Assuming VSAN restore is successful and overall status is healthy

1) Can you confirm by logging into Primary site VC-> Networking&Security>NSX HOME> Summary view to check if secondary NSX manager is showing there ?

2) I believe you have already checked Primary site VC-> Networking&Security>Installation and Upgrade> NSX Manager drop down view  ?

3) Double check by logging into secondary NSX Manager to confirm VC registration is intact and sync status is accurate.

4) Log-into Primary site NSX Manager and check under NSX Manager Summary to confirm if Universal services are running (If services are running ideally primary Site NSX is aware of secondary NSX instance)

5) Do you have any back up for NSX Managers ?

While checking all the services you've mentioned in both the primary and the secondary NSX Manager, the second NSX Manager now showed up from vCenter.

Everything is looking good.  Thank you.
