Environment

SDDC Manager 5.x
vCenter Server 8.x
vCenter Server 7.x

Cause

vCenter is unable to get the cached component (nsx-lcp-bundle) from the VCDB of the updatemgr service psql table PM_DEPOT_COMPONENTS, after vCenter update/upgrade.

Resolution

• Take a snapshot of the vCenter VM.
• If vCenter is in linked mode, power off all vCenters that are in linked mode, then take a snapshot of all the vCenters.
• VMware vCenter in Enhanced Linked Mode pre-changes snapshot (online or offline) best practice)

      1. Reset the vum DB Resetting the VMware Update Manager Database

      2. Create an empty vLCM-enabled cluster

• Log in to vCenter Server.
• In the Inventory view, right-click the vCenter Server object.
• Select New Cluster.
• Enable vSphere Lifecycle Manager (vLCM).
• Make sure to select "Import image from existing host" to avoid having to add a host to the cluster.

      3. Configure NSX on the newly created cluster

• Log in to the NSX Manager UI.
• Navigate to System > Fabric > Hosts and Clusters.
• Locate the newly created empty cluster and select the checkbox next to it.
• Click Add NSX at the top.
• Select the Transport Node Profile to use. This does NOT affect live traffic as the cluster is empty.
• Reconfigure the HA
• Remove the newly created empty cluster from vCenter after the HA tasks show as completed.
