When deleting a Virtual Machine (VM) from an Anti-affinity rule on Storage DRS (SDRS), users have observed that a random VM is deleted instead of the one intended. This issue has been identified as a bug in the Web User Interface (WebUI).
VMware vCenter Server 7.0
VMware vCenter Server 8.0
The WebUI send the incorrect managed object identifier (moid) of the VM that was selected in the "Edit Storage DRS Rule" modal.
Broadcom is aware of this issue and a fix will be implemented in a future 8.0x release
As a workaround, users can use PowerCLI or the API to delete VMs from the SDRS Anti-affinity rule.
