Getting started
In this section:
A high-availability Lustre file system managed by Integrated Manager for Lustre software requires that your entire storage system configuration and all interfaces comply with a pre-defined configuration. For detailed information, see High Availability Configuration Specification. If the system will leverage ZFS you may also want to read Creating and Managing ZFS-based Lustre file systems.
The Integrated Manager for Lustre software can be used to:
- Create, monitor and manage high-availability Lustre file systems, including systems running ZFS as the back-end.
- Monitor existing Lustre file systems that have not been created by IML.
See the following information to get started:
- To setup superuser and user accounts on Integrated Manager for Lustre software see: Creating user accounts.
- Also see: Setting up email notifications of alerts.
- To create a new Lustre file system using Integrated Manager for Lustre software, see: Creating a new Lustre file system.
- To detect and monitor an existing Lustre file system using Integrated Manager for Lustre software, see: Detect and monitor existing Lustre file systems.
WARNING: For Lustre file systems created and managed by Integrated Manager for Lustre software, the only supported command line interface is the CLI provided by Integrated Manager for Lustre software. Modifying such a Lustre file system manually from a UNIX shell will interfere with the ability of the Integrated Manager for Lustre software to manage and monitor the file system.
Creating user accounts
- Using the menu bar, click the Configuration drop-down menu and click Users.
- Click + Create user.
-
At the Create user dialogue window, select the new user’s role:
a) File system user - A file system user has access to the full GUI, except for the Configuration drop-down menu, which is not displayed. A user cannot create or manage a file system, but can monitor all file systems using the Dashboard, Alerts, and Logs windows. Users log in by clicking Login in the upper-right corner of the screen, and log out by clicking Logout.
b) Superuser - A superuser has full access to the application, including the Configuration drop-down menu and all sub-menus. A superuser can create, monitor, manage, and remove file systems and their components. A superuser can create, modify (change passwords), and delete users. A superuser cannot delete their own account, but a superuser can create or delete another superuser.
- Fill out the remainder of the Create user dialogue window and click Create.
- To set up email notifications of alerts for a user, see Setting up email notifications of alerts.
More about roles
A superuser must be logged in to perform any actions that modify the system, such as starting a file system or adding a server.
After logging in, a user can modify their own account by clicking Account near the upper-right corner of the screen. A user can set these options:
- Details - Username, email address, and first and last name can be changed.
- Password - Password can be changed and confirmed.
- Email Notifications - The types of events for which this account will receive emailed notifications can be selected from a checklist. If no notifications are selected, email notifications will be sent for all alerts except “Host contact alerts”. See Setting up Email Notifications of alerts.
Note: Unauthenticated users can access the static HTML content present on the Integrated Manager for Lustre software GUI, but the display will not be populated with current system information unless the user is authenticated.
Setting up email notifications of alerts
This feature lets a superuser selectively turn on and turn off email notifications of specific classes of alerts for individual users. Users can also configure this capability. The alert email has specific information as to which component is affected.
Note: A mail handler needs to be established to forward alert emails before this feature will work. See Editing Integrated Manager for Lustre software Configuration Settings for more information.
To set up email notifications:
- As the user, click Account in the upper right corner. Then click Email Notifications.
- Using the menu bar, click the Configuration drop-down menu and click Users. For the desired user, click Edit. Then click Email Notifications.
- At the Email Notifications window, select the alert types for which you want to turn on notifications. Alert classes include:
- Host contact alert - Host lost contact with a server.
- LNet offline alert - LNet is offline for a server.
