It is quite easy to reconfigure the UDA to patch your ESX host after the build process. All we need is NFS export on the UDA to act as a repository for the patches, a free-patching script and call statement in the kickstart script. Here’s how I do it (of course, everyone has their own preferred script/method):

Step One: First enable NFS on the UDA

Login to the UDA as root


  1. Edit the exports file with: nano -w /etc/exports
  2. Copy and Paste the existing line
  3. Paste and change the path to be
  4. /var/public/smbmount/DISK2
  5. Save the file and exit nano
  6. Restart the NFS service with: service nfs restart
  7. Create a directory at /var/public/smbmount/DISK2 called esxpatches with mkdir /var/public/smbmoun/DISK2/esxpatches 

Step Two: Upload the patching script & the patches in the tar.gz format

  1. From this web-site copy the script into the /var/public/smbmoun/DISK2/esxpatches
  2. From VMware’s website download and copy the patches to the same location

You will find Mike Knight’s script in the Free Tools section of this website

Step Three: Mount the NFS export in the kickstart script and execute the uda_esx_apply_patches

  1. To the script, add the following kickstart info

# Connect to UDA Source
service portmap start & service nfs start
esxcfg-firewall -e nfsClient
mkdir /tmp/udasource
mount /tmp/udasource

# Execute the
mkdir /var/updates
cp -v /tmp/udasource/esxpatches/* /var/updates
sh /var/updates/

# Clean up after using NFS on the UDA
# Unmount udasource, remove mounting point, stop services, close firewall
umount /tmp/udasource
rmdir /tmp/udasource
service nfs stop && service portmap stop
esxcfg-firewall -d nfsClient
