Changing Initial Passwords

Changing Initial Passwords

Scenarios

For security purposes, change the following passwords on the central management console (CMC) CLI:

  • Initial password of the default CMC user root
  • Initial password for the CMC U-Boot
  • Initial passwords of the default Hypervisor users
NOTE:
  • U-Boot is a primary boot loader that contains instructions to start the server's OS kernel. U-Boot performs basic configurations such as initializing hardware devices and setting up memory space mapping.
  • Hypervisor has three default users. One is root, which is used to log in to the Hypervisor CLI to perform operations such as configuration and upgrade. The other is klsftp, which is used to log in to Hypervisor through SFTP to upload or download files.
  • To ensure system security, change your initial password at the first login and change the password periodically.
  • A simple password is easy to crack, which makes the system vulnerable. You are advised to use a password that meets complexity requirements or to enable the password complexity check function.
  • The password complexity check function is enabled by default.
