Globally excluding devices

NOTE To perform any tasks on OpenManage Enterprise, you must have necessary user privileges. See Role-based OpenManage Enterprise user privileges.
NOTE Currently, you cannot exclude a device by using its hostname, but exclude only by using its IP address or FQDN.

When discovering device(s) from all the available devices, you can exclude certain device(s) from getting monitored by OpenManage Enterprise by doing the following:

  1. In the Global Exclusion of Ranges dialog box:
    1. In the Description of Exclude Range box, enter the information about the range that is being excluded.
    2. In the Enter Ranges to Exclude box, enter address(es) or range of devices to be excluded. The box can take up to 1000 address entries at a time, but separated by a line break. Meaning, every exclusion range must be entered in different lines inside the box.
      The range that can be excluded is same as the supported ranges that are applicable while discovering a device. See Create a device discovery job.
    NOTE
    • The range size is limited to 16,385 (0x4001).
    • The IPv6 and IPv6 CIDR formats too are supported.
  2. Click Add.
  3. When prompted, click YES.
    The IP address or the range is globally excluded, and then displayed in the list of excluded ranges. Such devices are globally excluded which implies that they do not take part in any activity performed by OpenManage Enterprise.
    NOTE The device that is globally excluded is clearly identified as 'Globally excluded' on the Job Details page.
    You can view the list of globally excluded devices by clicking:
    • Devices > Global Exclude. The Global Exclusion of Ranges dialog box displays the list of excluded devices.
    • Monitor > Discovery > Create > Global Exclude. The Global Exclusion of Ranges dialog box displays the list of excluded devices.
    • Monitor > Discovery > Global Exclusion List. The Global Exclusion of Ranges dialog box displays the list of excluded devices.
    To remove a device from the global exclusion list:
    1. Select the check box and click Remove from Exclusion.
    2. When prompted, click YES. The device is removed from the global exclusion list. However, a device removed from the global exclusion list is not automatically monitored by OpenManage Enterprise. You must discover the device so that OpenManage Enterprise starts monitoring.
NOTE Adding devices that are already known to the console (meaning, already discovered by the console) to the Global Exclusion List will remove the device(s) from OpenManage Enterprise.
NOTE The newly-included devices to the Global Exclusion List continues to be seen in the All Devices grid till the next Discovery cycle. To avoid performing tasks on such devices, it is highly recommended that the user manually excludes them from the All Devices Page by selecting the check box corresponding to the device(s) and then clicking Exclude.
NOTE Devices listed in the Global Exclusion List are excluded from all tasks in the console. If the IP of a device is in the Global Exclusion List and a discovery task is created where the range for discovery includes that IP, that device is not discovered. However, there will be no error indication on the console when the discovery task is being created. If you expect that a device must be discovered and it is not, you must check the Global Exclusion List to see if the device has been included in the Global Exclusion List.
