The required action is to perform an inventory sync . In VCF Operations Fleet Management, vertical scale-up depends on current inventory data from the managed component. The scale workflow first validates that the Fleet Management appliance has an accurate view of the VCF Operations cluster, including node inventory and placement information. The documented vertical scale-up workflow states that after selecting Fleet Management > Lifecycle > Components , choosing the component, and selecting Vertical Scale Up , the administrator must acknowledge the downtime warning and click Trigger Inventory Sync to synchronize the VCF Operations Fleet Management appliance with the latest data from the cluster. After the inventory sync completes successfully, the administrator can click Proceed and continue selecting nodes and target scale-up sizing . Mandatory snapshots are not the corrective action for stale inventory. Taking the cluster offline is not the manual remediation for the “Needs Attention” inventory condition, although nodes are restarted during the scale operation. Scaling Cloud Proxies is unrelated to vertically increasing VCF Operations management-node resources.
