When configuring a storage system in a MetroCluster configuration, you must make sure that the high-availability (HA) state of the controller module and chassis components is mcc or mcc-2n so that these components boot properly.
The system must be in Maintenance mode.
- In Maintenance mode, display the HA state of the controller module and chassis: ha-config show
The correct HA state depends on your MetroCluster configuration.
| Number of controllers in the MetroCluster configuration | HA state for all components should be... |
|---|
| Eight- or four-node MetroCluster FC configuration | mcc |
| MetroCluster IP configuration | mccip |
- If the displayed system state of the controller is not correct, set the HA state for the controller module:
| Number of controllers in the MetroCluster configuration | Command |
|---|
| Eight- or four-node MetroCluster FC configuration | ha-config modify controller mcc |
| MetroCluster IP configuration | ha-config modify controller mccip |
- If the displayed system state of the chassis is not correct, set the HA state for the chassis:
| Number of controllers in the MetroCluster configuration | Command |
|---|
| Eight- or four-node MetroCluster FC configuration | ha-config modify chassis mcc |
| MetroCluster IP configuration | ha-config modify chassis mccip |
- Boot the node to ONTAP: boot_ontap
- Repeat these steps on each node in the MetroCluster configuration.
