Instructions

You can reset the password of the default admin user (Superuser) using the combination of a file written to the MDM and the reset_admin CLI command.

Prerequisites

Ensure that you are using the admin user with Superuser permissions.

About this task
NOTE: The procedure refers only to the default admin user with Superuser permissions, which was created during the system setup.
Steps
Option 1

1- Create a text file named MDM_SERVICE_MODE on the MDM in the location corresponding to your operating system:

Windows: C:\Program Files\emc\scaleio\MDM\logs\MDM_SERVICE_MODE
Linux: /opt/emc/scaleio/mdm/logs/MDM_SERVICE_MODE

2- In the body of the file, type the text Reset Admin, and save the file.

3- From the CLI, run the reset_admin command:

scli --reset_admin

 

Option 2

One-line command 

echo "Reset Admin" > /opt/emc/scaleio/mdm/logs/MDM_SERVICE_MODE && scli --reset_admin && scli --login --username admin --password admin

 

Results

The admin user password is reset to admin.

 

The current password must be changed to the preferred password using the following command 

# scli --set_password --old_password admin --new_password <MyNewPassowrd!!>
Password changed successfully

Note: In emergency cases, you may need to use this procedure to override the LDAP authentication and restore the Superuser (admin) so that the authentication method becomes both LDAP and native authentication 

 

 This procedure can be run from the iDRAC console if the node is not accessible
