The need to replace an NSX Edge node arises when an existing physical server fails or when you want to replace the VM form factor to a physical server form factor. But, there could be other reasons for replacing the hardware, such as node reaching defunct status and so on.
Prerequisites
- (Physical servers and NSX Edge VMs manually deployed through vSphere Client) Before you replace a NSX Edge node, ensure connectivity between the existing NSX Edge node and NSX Manager is down. If connectivity is Up, NSX does not allow the existing NSX Edge node to be replaced with a new one.
- Starting with NSX 4.0.1.1, NSX Edge VM hardware version will no longer default to virtualHW.version 13. NSX Edge VM hardware will depend on the underlying version of the ESXi host. VM hardware versions compatible with ESXi hosts are listed in KB article 2007240.
Procedure
What to do next
After you run del nsx on the host, old entries of logical routers, VTEP IP addresses, uplink IP addresses are released. You can now prepare the replaced physical server as an NSX transport node.
