Issue/Introduction

Devices are deleted successfully using the Operator Console (OC) Deep Clean option

 

However, the robot processes remain running on the server.

Environment

  • DX UIM 23.4.2
  • RHEL 8

 

Cause

Delete devices (Deep Clean) cleanup process failure may vary due to one or more of the following:

  • robot version not 23.4.2
  • robot communication issues
  • robot not up and running
  • robot hung
  • one or more of the robot processes (controller, hdb, or spooler) is down/red hung
  • robot is a hub not just a robot
  • networking issues
  • access/permissions/ACL
  • server/robot already decommissioned
  • environmental
  • other/unknown causes
  • Spooler may be down

Resolution

Ensure that you meet the following prerequisites for bulk on-boarding/decommissioning of devices using Deep clean in DX UIM v23.4 CU2:

  1. Controller and Hub must be v23.4.2 or later
  2. Robot_update v23.4.2 or later
  3. UIMAPI v23.4.2 or later (when using the UIMAPI)
  4. automated_deployment_engine v23.4.2 or later

Consideration for Bulk On-boarding/Decommissioning of Devices (From DX UIM v23.4 CU2):

  • Robot decommissioning is supported on Windows and Linux only.
  • Robot decommissioning is not supported for robots installed as 'non-admin.'
  • Note that hub queues need to be manually cleared from the respective hubs to clean up the queues for the decommissioned robot.
  • When a device or robot is not reachable or down, robot decommissioning does not work. You must re-trigger the device decommissioning when the robot is up and running.

Scenarios: 

 

  • Halting hub robot uninstallation - This happens if you try to do a deep clean on a hub. The state for this job will go to Paused.

  • Halting oc robot uninstallation - This happens if you try to do a deep clean on an OC robot. If there is a desire to decomm a secondary OC, than OC need to be uninstalled first. The state for this job will go to Paused.

  • UnblacklistDevices as Delete Robot has failed - This happens if you do a deep clean on a version 23.4.1 or lower robot, where blacklist is not selected. (and deep clean is not supported). This can also happen on a robot that is 23.4.2 or greater where deep clean is selected, but the robot is not running. The robot must be running to perform deep clean.
    Stage = Revoking BlacklistDevices
  • Received status (11) on response (for sendRcv) for cmd = '_uninstall_robot' - This happens if you do a deep clean on a version 23.4.1 or lower robot, where blacklist was also selected. (deep clean not supported)

  • Received status (4) on response (for sendRcv) for cmd = 'nametoip' name = '/my_domain/my_hub/my_robot/controller' - This happens when a 23.4.2 or greater robot is shut down and both blacklist and deep clean are selected. The robot must be running.
    Stage = Delete Robot
