Organizing devices into groups

In a data center, for effective and quick device management, you can:
  • Group the devices. For example, you can group devices based on functions, OSs, user profiles, location, jobs run, and then run queries to manage devices.
  • Filter the device-related data while managing devices, updating firmware, discovering devices, and managing alert policies and reports.
  • You can manage the properties of a device in a group. See Viewing and configuring devices.

OpenManage Enterprise–Tech Release provides a built-in report to get an overview of the OpenManage Enterprise–Tech Release monitored devices. Click OpenManage Enterprise > Monitor > Reports > Devices Overview Report. Click Run. See Running reports.

NOTE: To perform any tasks on OpenManage Enterprise–Tech Release, you must have necessary user privileges. See Role-based OpenManage Enterprise–Tech Release user privileges.

To view Dashboard data pertaining to selected devices or groups, select from the Device Groups drop-down menu.

NOTE: The health status of a device or group is indicated by appropriate symbols. The health status of a group is the health of a device in a group that has the most critical health status. For example, among many devices in a group, if the health of a server is Warning then the group health is also 'Warning'. The rollup status is equal to the status of the device that has high severity. For more information about Rollup Health status, see the MANAGING THE ROLLUP HEALTH STATUS BY USING IDRAC ON THE DELL EMC 14TH GENERATION AND LATER POWEREDGE SERVERS technical white paper on the Dell TechCenter.

Groups can have a parent and child group. A group cannot have its parent groups as its own child group. By default, OpenManage Enterprise–Tech Release is supplied with the following built-in groups.

System Groups: Default groups created by OpenManage Enterprise–Tech Release. You cannot edit or delete a System Group, but can view and hide based on user privileges. Examples of System Groups:

  • HCI Appliances: Hyper-converged devices such as VxRAIL and Dell EMC XC series devices
  • Hypervisor Systems: Hyper-V servers and VMware ESXi servers
  • Modular Systems: PowerEdge Chassis, PowerEdge FX2, PowerEdge 1000e chassis, and PowerEdge VRTX chassis
  • Network Devices: Dell Force10 networking switches and Fibre Channel switches
  • Servers: Dell iDRAC servers, Linux servers, Non-Dell servers, OEM servers, and Windows servers
  • Storage Devices: Dell EMC Compellent Arrays
  • Discovery Groups: Groups that map to the range of a discovery task. Cannot be edited or deleted because the group is controlled by the discovery job where the include/exclude condition is applied. Currently, 5500 discovered devices can be monitored by OpenManage Enterprise–Tech Release. See Discovering devices for monitoring or management.

NOTE: To expand all the subgroups in a group, right-click the group, and then click Expand All.

Custom Groups: Created by the user for specific requirements. For example, servers that host email services are grouped. Users can view, edit, and delete based on user privileges and group types.
  • Static Groups: Manually created by the user by adding specific devices to a group. These groups change only when a user manually changes the devices in the group or a sub-group. The items in the group remain static until the parent group is edited or the child device is deleted.
  • Query Group: Groups that are dynamically defined by matching user-specified criteria. Devices in the group change based on the result of devices that are discovered by using criteria. For example, a query is run to discover servers that are assigned to the Finance department. However, the Query Groups have a flat structure without any hierarchy.

NOTE: Static and Query groups:

  • Cannot be mixed.
  • Cannot have more than one parent group. Meaning, a group cannot be added as a sub-group under its parent group.

NOTE: Creating more number of Custom (Query) groups in the device group hierarchy impacts the overall performance of OpenManage Enterprise–Tech Release. For optimized performance, OpenManage Enterprise–Tech Release captures the health-rollup status after every 10 seconds—having more number of Dynamic groups affects this performance.

On the All Devices page, in the left pane, you can create child groups under the parent Static and Query group. See Creating or editing a Static device group and Creating a Query device group.

NOTE: To perform any tasks on OpenManage Enterprise–Tech Release, you must have necessary user privileges. See Role-based OpenManage Enterprise–Tech Release user privileges.

To delete the child group of a Static or Query group:
  1. Right-click the Static or Query group, and then click Delete.
  2. When prompted, click YES. The group is deleted and the list under the group is updated.
