Creating a User Group

Scenario

This section describes how to create user groups and specify their operation permissions on MRS Manager. Management of single or multiple users can be unified in the user groups. After being added to a user group, users can obtain operation permissions owned by the user group.

Up to 100 user groups can be created on MRS Manager.

Prerequisites

Administrators have learned service requirements and created roles required by service scenarios.

Procedure

  1. On MRS Manager, click System.
  2. In the Permission area, click Manage User Group.
  3. Above the user group list, click Create User Group.
  4. Set Group Name and Description.

    Group Name is mandatory and contains 3 to 20 digits, letters, and underscores (_). Description is optional.

  5. In Role, click Select and Add Role to select and add specified roles.

    If you do not add the roles, the user group you are creating now does not have the permission to use MRS clusters.

  6. Click OK. The user group is created.
