Changing the System Password

Changing the System Password

The OceanStor 9000 system requires a correct system password to gain access. You are advised to periodically change the system password to eliminate information leakage.

The root account is automatically generated in the OceanStor 9000 Linux operating system. You are advised to change your password periodically. The new password must meet the password complexity policy.

Following methods of changing the password:

  • Log in to the system using PuTTY as user root. Enter passwd and set a new password for user root.
  • CLI command method:
    1. Use SSH to log in remotely to the management storage node (marked with a cluster management IP address) as user root.
    2. Run /startup_disk/image/ISM/ism_ap/CLI/ismcli/ -u admin -ip -port 8080 to log in to the CLI.
    3. Run change system root_password to enter a password as prompted.
  • Log in to DeviceManager, choose Settings > Cluster Settings > Cluster Node Settings, select the nodes whose passwords you want to change, and click Change root Password.

Password complexity policy:

  • When changing the password using PuTTY, the password must be at least 8 characters. When changing the password using CLI or DeviceManager, the password must be 8 to 16 characters in length.
  • Contains special characters and any two types of lowercase letters, uppercase letters and digits.
  • It cannot be the same as the user name or the user name typed backwards.
  • When changing the password using PuTTY, the password cannot be the same as the used passwords or part of one used password.
