Disable the security-mode Variable


Caution  -  When security-mode is set to none, the OpenBoot password is not automatically cleared. If security-mode is later enabled, the existing password takes effect. If the original password is forgotten, you cannot use your virtual machine and you must call your vendor's customer support service to make your virtual machine bootable again. To avoid this scenario, always clear the password when you disable the security-mode, as described in this procedure.

  1. Access the OpenBoot CLI.

    See Accessing the OpenBoot CLI and Getting Help.

  2. Set the security-mode variable to none.
    {0} ok setenv security-mode none
  3. Set the password to zero length by typing Return after both password prompts.
    {0} ok password
    New password (8 characters max):
    Retype new password: 
    {0} ok
