### Understanding User Accounts and Roles

The Sun StorEdge 6320 System is configured with three user accounts and the Sun StorEdge 6120 Array is configured with three user roles shown in the table. The software enables the `admin` user or role to authorize users to access the system and the software, and to set passwords for the accounts or roles. The user accounts and roles are as follows:

User Account or Role | Description
--- | ---
`admin` | An `admin` user or role has all administration privileges. The `admin` user can add, modify, and delete users and modify system attributes on the Administration 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.
