Quick Fix – No Datastores after ESXi 7.0 Upgrade on SuperMicro with Intel Based SATA Adapters
As usual, I like to jump right into software upgrades to test out new functionality (on none production systems of-course). With the GA of vSphere7 overnight, I went about upgrading my Homelab vCenter and ESXi host. The vCenter upgrade went well, but I ran into an issue after I upgraded the ESXi Host using the online bundle upgrade.

So my assumption was that because the Intel Drivers where only compatible up to ESXi 6.7, with the Default VMware drivers disabled, there was no fall back. As William Lam states here, the original performance issue was fixed in Update 1 of 6.5, and suggested to re-enable the Default VMware AHCI driver. After re-enabling the drivers, I rebooted and tried the upgrade again… this time with success and with all the Datastores listed.
