Hi everyone, I have one question about the software upgrade on VxRail Appliance, I know that we need to download software package which includes the following components: VxRail Manager, VMware vCenter Server Appliance, VxRail Manager VIB and VMware ESXi. We just upload this software package into VxRail Manager and perform the software upgrade by VxRail Manager. It starts the pre-check first before software upgrade. Based on my knowledge about VxRail Appliance, the upgrade flow is VxRail Manager -> VMware vCenter Server Appliance -> VMware ESXi -> VxRail Manager VIB. As we’ve neither control nor knowledge on the whole upgrade process, how to handle any instance should something goes wrong in this upgrade program? Please advise.
