Day-2 Operations¶
Operational procedures for managing the cluster after installation and configuration. These demonstrate that the customer team can independently perform common lifecycle tasks — a key POC success criterion.
| Procedure | What It Demonstrates | Typical Time |
|---|---|---|
| Cluster Upgrade | Apply a z-stream or minor version update (minimal disruption with PDBs / LiveMigrate) | 45–90 min |
| Hardware Firmware Updates | Update BIOS, BMC, and adapter firmware on bare metal, one node at a time | 30–90 min per node |
| Add Worker Node | Expand cluster capacity by adding a new worker node via ISO | 20–30 min |
| Rotate SSH Keys | Replace SSH keys on cluster nodes using MachineConfig | 10–15 min per pool |
| Machine Config | Create and apply node-level configuration with MachineConfig and Butane | 10–15 min per pool |
| must-gather | Collect cluster diagnostics for troubleshooting and support cases | 5–15 min |
| Debugging MTU Mismatches | Diagnose and fix MTU-related connectivity issues | Varies |
Recommended for Every POC
At minimum, demonstrate Cluster Upgrade and must-gather — these are the two day-2 tasks most commonly asked about by operations teams evaluating OpenShift.
