Which three actions are Day 1 Operations for VxRail API requests?

The VxRail REST API classifies orchestration tasks into separate operational boundaries, explicitly distinguishing between Day 1 (initialization and deployment) and Day 2 (ongoing lifecycle management) requests. Day 1 operations are exclusively bound to the automated processes required to bring a fresh, unconfigured set of bare-metal nodes up to a fully realized hyperconverged cluster infrastructure. This includes executing a discovery scan across the physical network segment to locate candidate nodes, invoking the deployment engine to programmatically apply the system design specification, and programmatically monitoring the initialization build sequence.

Specifically, the corresponding VxRail API endpoints utilized during this architectural phase include queries to discover unconfigured nodes on the local fabric, POST /v1/system/initialize to launch the automated deployment, and GET /v1/system/initialize/status to track execution milestones. Alternative operations, such as expanding an operational cluster by adding nodes or executing automated software runtime upgrades, are explicitly classified as Day 2 lifecycle management workflows. These Day 2 tasks require a pre-existing, fully initialized production environment and an active integration with the vCenter management layer.
