Resetting the Password of the Cluster Administrator


This section describes how to reset the password of the cluster administrator account on the Cluster Management page when the administrator forgets the password or the administrator account is locked after 10 consecutive incorrect password attempts.


  1. Log in to the management console at https://console.otc.t-systems.com/dws/.
  2. Click Cluster Management.
  3. In the Operation column of the target cluster, choose More > Reset Password.

  4. On the displayed Reset Password page, set a new password, confirm the password, and then click OK.

    The password complexity requirements are as follows:
    • Consists of 8 to 32 characters.
    • Cannot be the same as the username or the username written in reverse order.
    • Must contain at least 3 of the following character types: uppercase letters, lowercase letters, digits, and special characters ~!@#%^&*()-_=+|[{}];:,<.>/?
    • Passes the weak password check.
    • Be different from the old password and cannot be the reverse of the old password.
    • Cannot use a history password.

    If the default administrator account of the cluster is deleted or renamed, password resetting fails.
