What happened to vSphere 7.0 U3 ?
vSphere 7.0 Update 3 was initially released on October 5, 2021. Shortly after release, there were a number of issues reported by customers, so on November 18, 2021, all ESXi versions 7.0 U3a, U3b, U3c, as well as vCenter 7.0 U3b were withdrawn from VMware’s download area. VMware explains details of the issue in KB 86191.
The main reason was a duplicate driver i40en and i40enu for Intel 10 GBit NICs X710 and X722 in the system. A check on the CLI returns a result quickly. Only one result may be returned here.

Hosts with both drivers will potentially have HA issues when updating to U3c, as well as issues with NSX.
What’s new with Update 3c ?
On 27 January 2022 ( 28 January 2022 CET) the new Update 3c was released and is available for download. Besides fixing the issues from previous Update 3 versions (KB 86191), the main feature is the fix for the Apache Log4j vulnerability (VMSA-2021-0028.10).
All users and customers who had installed one of the withdrawn updates 3 at an early stage are highly recommended to update to version U3c.Continue reading “VMware vSphere 7.0 U3c released”
