### Understanding User Accounts and Roles

The Sun StorEdge 6300 System is configured with three user accounts as shown in the table. The software enables the `admin` user to set passwords for the accounts. Each account uses the software with the role of the same name.

The Sun StorEdge 6100 System is configured with three user roles as shown in the table. The software enables the `admin` role to authorize users to access the system and the software. By default, the system is pre-configured with the root user assigned access to the admin role.

User Account or Role | Description
--- | ---
`admin` | 6300 Systems - An `admin` user has all administration privileges. The `admin` user can modify system attributes on the Administration page and set passwords for the accounts. 6100 Systems - An admin user is, by default, the root user. The root (admin) user can add, modify, and delete users and modify system attributes on the Administrator page.
`storage` | A `storage` user or role can use most of the software features related to storage device configuration. The Administration page is available to this user as read-only; this user cannot modify admin settings. This user can use the features available from the Array Management and Storage Access pages.
`guest` | A `guest` user or role has read-only privileges and can view the information. This user cannot modify any settings or feature.

Note - Only the admin user or role can change the passwords.
