Then ESXi hosts reach 100% of the CPU, and all VMs have a huge impact on performance. All VMs continue to work but not able to power down, power up, no migrations anything. Since there is no access to the SD card and system partitions, the ESXi host hangs, and it is impossible to do anything.

VSphere 7 Update 2 when is running on an SD Card simply loses connection to the SD Cards, and ESXi host freezes. I move all our scratch and coredump partitions to a Storage Datastore, so not running any of those partitions or logs on SD Cards. Note: Some unofficial statements from VMware employees say that a new patch to fix this issue(and others) will be launched on 15th of July. You use the patch, instead of this workaround.Ĭheck here in my other blog post about the patches for this issue and how to apply. There is already a patch to fix this issue. More information about this issue: KB83963 KB83782 Information about these: kb2077516and kb83376or in the What is new, The issue that we had in vSphere U1, fixed in U2 and is not related to this issue. Note: This problem is not related to vSphere 7 new partitions or /scratch or /coredump partition when running on an SD Card. If you upgrade from vSphere 6.7 to 7 update 2 or install vSphere 7 Update 2 in an SD Card, then have or will get this huge problem soon.

If you are one of the unlucky ones with vSphere 7 Update 2 loses connection with SD Cards a Workaround, then I feel your pain.
