 When a new Cluster is created, the credentials are automatically rotated during deployment. The managed credential process then automatically rotates these credentials periodically based on the credential type. The updated credentials are written to the key vault associated with the Cluster resource.

+The 2024-07-01-GA version of the Network Cloud API added the credential rotation status on the Bare Metal Machine and Storage Appliance resources. This information can be found in the secretRotationStatus data construct for each of the rotated credentials. The 2025-07-01-preview & subsequent versions of the API adds the keyVaultUri to this data construct to indicate which Key Vault contains the rotated secret.

 In order to restore the state of the credential, it must be reset to a value that the platform recognizes. There are two options for this situation:
 
-1. Run a [BareMetalMachine replace](./howto-baremetal-functions.md) action providing the current active credentials. The replace action allows the machine to use provided credentials to reset credential rotation. This is the recommended option if significant changes are made to the machine.
-1. Reset the BMC credential back to the value prior to the manual change. If a key vault is configured for receiving rotated credential, then the proper value may be obtained using information from the `secretRotationStatus` data for the Bare Metal Machine resource. The rotation status for the BMC Credential indicates the secret key and version within the key vault for the appropriate value. Once the credential is set to match the value expected by the credential rotation system, rotation will proceed normally.
