Upgrading VMware vSphere

Important: SDS device errors associated with maintenance mode on the production Cluster may occur when upgrading VxFLEX OS from version 2.0.1.4 to version 2.6.0. Device errors may dispaly in the VxFlex OS GUI on the SDS currently in maintenance mode after removing the ESXi Host from maintenance mode and re-starting the SVM. Before taking the SDS out of maintenance mode, clear the device errors by selecting all the devices with errors, right click and select clear device errors.
