## Data Object Description

Preflight check status. Various pieces of information useful to the user before performing a VIB install.

Properties

Name | Type | Description
--- | --- | ---
manualVmotionRequired | xsd:boolean | True if DRS is not configured/enabled in a way that would automatically move VMs when performing EnterMaintenanceMode_Task(). In such cases vSAN will issue the EnterMaintenanceMode_Task() call, but users need to assist in vMotion of any VMs on that host, either by using DRS manual recommendation application, or by fully manual vMotion.
rollingRequired | xsd:boolean | True if there are powered on VMs on the cluster which prevent a all-at-once install of VIBs across the cluster. Only relevant when the VIBs that need to installed require maintenance mode.
