Removing NSX-T VIBs from ESXi hosts

10/31/2017

I’d wanted to revert my environment from (an incomplete install of) NSX-T v2.0 back to NSX for vSphere v6.3.x, but found that the hosts would not complete preparation.  The logs indicated that something was “claimed by multiple non-overlay vibs”.

Error in esxupdate.log

I found that the hosts still had the NSX-T VIBs loaded, so to remove them, here’s what I did:

  1. Put the host in maintenance mode.  This is necessary to “de-activate” the VIBs that may be in use
  2. Login to the host via SSH
  3. Run

    /etc/init.d/netcpad stop
    /etc/init.d/nsx-ctxteng stop remove
    /etc/init.d/nsx-da stop remove
    /etc/init.d/nsx-datapath stop remove
    /etc/init.d/nsx-exporter stop remove
    /etc/init.d/nsx-hyperbus stop remove
    /etc/init.d/nsx-lldp stop remove
    /etc/init.d/nsx-mpa stop remove
    /etc/init.d/nsx-nestdb stop remove
    /etc/init.d/nsx-platform-client stop remove
    /etc/init.d/nsx-sfhc stop remove
    /etc/init.d/nsx-support-bundle-client stop remove
    /etc/init.d/nsxa stop remove
    /etc/init.d/nsxcli stop remove

  4. Run this all in one line; note the the order of the vibs is important

    esxcli software vib remove -n nsx-ctxteng -n nsx-hyperbus -n nsx-platform-client -n nsx-nestdb -n nsx-aggservice -n nsx-da -n nsx-esx-datapath -n nsx-exporter -n nsx-host -n nsx-lldp -n nsx-mpa -n nsx-netcpa -n nsx-python-protobuf -n nsx-sfhc -n nsx-support-bundle-client -n nsxa -n nsxcli -n nsx-common-libs -n nsx-metrics-libs -n nsx-nestdb-libs -n nsx-rpc-libs -n nsx-shared-libs -n nsx-python-gevent -n nsx-python-greenlet

  5. reboot the host
