Uninstalling an IBM Storage Defender sensor through the UI

You can uninstall the sensor on one or multiple systems through the IBM Storage Defender UI.

To uninstall an IBM Storage Defender sensor on one or multiple systems, complete the following steps:

1. Log in to IBM Storage Defender.
2. Click the hamburger menu on the upper left corner of the page.
3. Click Data Resiliency > Recovery Groups.
4. From the list of recovery groups, click the row in the table for the recovery group that you are interested in.
5. On the recovery group's Overview dashboard, in the Defender Sensors tile, click Manage.
6. Select one or multiple VMs by clicking the check box for which you want to remove the sensors.
   Note: The connection manager uses FQDNs of the VMs for sensor installation or uninstallation operations. Therefore the IBM Storage Defender sensor uninstallation UI does not allow the selection of the following VMs:

   • VMs with no FQDN
   • VMs with localhost set as the FQDN
   • VMs with identical FQDNs

   Any changes on the VMs network configurations will be reflected in the UI after the next automatic or manually-triggered inventory scan. The automatic inventory scan interval is one hour.
7. Click the Remove Sensor button in the title bar.
8. Enter either a username and password, or the SSH key to access the virtual machine.
   Note: All selected VMs must have the same login credentials.
9. Click Remove Sensor to submit the uninstall request.
10. Check the state of VMs that change to Uninstalling.
    Tip: Monitor the Notification menu to check for completed or failed notifications for each sensor. If the status is TIMEOUT, the uninstallation request was accepted but did not respond for 15 minutes. For the FAILED status, check the detailed error message in the notification.

    Important: If you are trying to uninstall a sensor that belongs to a connection manager that is destroyed or not properly backed up and restored during a connection manager OVA upgrade, the sensor uninstallation fails.
