After upgrading Cisco Nexus 1000V VSM to the latest version, you might not be able to patch the kernel of ESX hosts attached to the vDS (1015717)

Details

Upgrading Cisco Nexus 1000V VSM to the latest version upgrades the Cisco VEM modules on ESX hosts attached to the vDS. Subsequently, from the same vSphere Client instance, you might not be able to use a host patch baseline to apply patches to the ESX vmkernel64 or ESXi firmware of hosts attached to the vDS. Applying patches to ESX vmkernel64 or ESXi firmware requires that you include the compatible Cisco Nexus 1000V VEM patch in the baseline. However, this patch might not be available for selection in the Update Manager New Baseline wizard or in the Update Manager patch repository.

This issue is present in Update Manager 4.0 Update 1.

Solution

Make Cisco Nexus 1000V VEM patches available for inclusion in host patch baselines by taking either of the following approaches:
  • Restart the vSphere Client.
  • Disable and re-enable the Update Manager plug-in.

To disable and re-enable the Update Manager plug-in:
  1. Open the vSphere Plug-in Manager.
  2. Right-click VMware vCenter Update Manager Extension and select Disable.
  3. Right-click VMware vCenter Update Manager Extension again and select Enable.
