VMWare has pulled vSphere 7.0 Update 3

VMware has discovered multiple issues with vSphere ESXi 7.0 Update 3, 3a, and 3b and vCenter 7.0 Update 3b. These versions are no longer available for download. If you downloaded any of these builds before VMWare pulled them, DO NOT install these updates.

The ESXi updates can cause the Purple Screen of Death (PSOD) and crash the host under certain circumstances. Here are links to known issues with these updates: https://kb.vmware.com/s/article/86287 and https://kb.vmware.com/s/article/86281. One client installed vSphere 7.0 Update 3, and it changed the iSCSI Qualified Name (IQN) on the host, which caused all of the shared SAN storage to go missing. If you have any issues that are not resolved by the VMware Knowledgebase articles, open up a support case with VMware.
