Bare Metal Orchestrator requires three partitioned disks mounted on the Global Controller (CP1), For high availability (HA), each of the redundant HA nodes (CP2 and CP3) must have matching disks mounted.
The following shows an example of the storage partitions that are mounted on a Global Controller node: sda and sdb.
If the mounted partitions are incorrectly assigned, you can reboot the nodes to change the mounted partition assignments using the operating system.
For more information about partition assignments and requirements, see Storage requirements.
