+### osdctl cluster change-ebs-volume-type
+
+Change the EBS volume type for control plane and/or infra nodes on a ROSA/OSD cluster.
+
+This command replaces machines to change volume types (not in-place modification).
+For control plane nodes, it patches the ControlPlaneMachineSet (CPMS) which automatically
+rolls nodes one at a time. For infra nodes, it uses the Hive MachinePool dance to safely
+replace all infra nodes with new ones using the target volume type.
+
+Pre-flight checks are performed automatically before making changes.

+
+### Examples
+
+```
+  # Change both control plane and infra volumes to gp3

+```

+### Options
+
+```
+  -C, --cluster-id string   The internal/external ID of the cluster
