We have been having the same problem since last October when we upgraded to esxi 6.5 and in turn started using the i40en nic driver. With this driver on every few weeks one of our hosts locks up. This post nails the problem better than I can describe https://communities.vmware.com/thread/552470?start=15&tstart=0 Install ESXi 6.5 on R730 with Intel X710 |VMware Communities
Our workaround was to downgrade to the i40e version, unfortunately doing this makes VMware non compliant in update manager and because us IT guys have serious OCD its very annoying. It's also not good as we like to keep a visual view of these hosts so we know when to patch them.
Is this issue going to be fixed? Just to note on more than one occasion we have had production hosts go down because of this issue and we have had to explain to our staff.
Same issue occurs whether it has Dell branding or not; it's still the same underlying broken card with the same broken driver i40en. Other threads:
Firstly, thank you for trying to help I understand it cannot
be easy for you trying to deal with frustrated customers. We have now sent an
email to our account manager and hopefully from our perspective they can send
us some new nic's which aren't this model because they are clearly a problem.
Just to state we have had about 6 outages due to this
issue, all when we upgraded our ESXi host 6.5 and it stated using this driver.
Please note when these outages occurred we had core system on these hosts such
as Microsoft exchange causing a companywide outage. One of these outages was at
4am and because we have an Asia office, I was woken up with a rather angry
phone call. Since we have downgraded our driver, the crashes have gone away entirely
although update manager is saying we are non-compliant with this driver missing.
In addition, when we patch a host the updates always include this driver, which
means we have to roll back this driver as part of the process or our ESX
servers will eventually lockup due to this issue.
Looking at the links ispcolohost has added this is not
just on Dell branded kit. Even if it is on Dell branded cards really as a customer,
it is not my problem to help Intel and Dell to work on the resolution process.
At the end of the day as a customer, I do not want to deal with the politics
between Intel and Dell. I do hope this issue are addressed in the next release
driver release for the i40en.
Thank you for the reply and I am sorry to hear about the outage encountered. I received an update about regarding Malicious Driver Detection (MDD) Error, and this will be addressed in the next driver release. Please refer to information below:
This Malicious Driver Detection is and open issue for ESX i40en driver version 1.5.8..
The Malicious Driver Detection issue that we are aware of will be addressed in the next i40en driver release. The next driver is going through VMware Certification process and expected to release in a couple of weeks. We will have an official statement on this issue by next week.
Please wait for our further update, thank you for your patience on this matter.
