After successfully completing the migration from vCenter 6.0 (on Windows) to the vCenter 6.5 Appliance, all I had remaining was to upgrade my ESXi hosts to ESXi 6.5.

In my test environment, I run 2 x HPe Proliant DL360p Gen8 servers. I also have always used the HPe customized ESXi image for installs and upgrades.

It was easy enough to download the customized HPe installation image from VMware’s website, I then loaded it in to VMware Update Manager on the vCenter appliance, created a baseline, and was prepared to upgrade the hosts.

I successfully upgraded one of my hosts without any issues, however after scanning on my second host, it reported the upgrade as incompatible and stated: “The upgrade contains the following set of conflicting VIBs: Mellanox_bootbank_net.XXXXversionnumbersXXXX. Remove the conflicting VIBs or use Image Builder to create a custom ISO.”

I checked the host to see if I was even using the Mellanox drivers, and thankfully I wasn’t and could safely remove them. If you are using the drivers that are causing the conflict, DO NOT REMOVE them as it could disconnect all network interfaces from your host. In my case, since they were not being used, uninstalling them would not effect the system.

I SSH’ed in to the host and ran the following commands:

esxcli software vib list | grep Mell (This shows the VIB package that the Mellanox driver is inside of. In my case, it returned “net-mst”)

esxcli network nic list (this command verifies which drivers you are using on your network interfaces on the host)

esxcli software vib remove -n net-mst (this command removes the VIB that contains the problematic driver)

After doing this, I restarted the host, scanned for upgrades, and successfully applied the new vCenter 6.5 ESXi Customized HPe image.

  1. […] A note on a problem I dealt with during ESXi 6.5 upgrade (conflicting VIBs marking image as incompatible when deploying HPe customized image) can be found here: […]

  2. Just went through this myself, thanks for the post! A few notes:

    The VIBs my esxi hosts complained about were different, but still not used, so I had to change the grep/remove commands to match

    The VIB remove commands take a loooong time on my boxes to execute, like 5+ min, and I thought they were stalled/doing something horrible. Nope, they just take a long ass time.
