Unrelated Volumes Displayed in AppStack
Unrelated volume objects may be displayed within the AppStack resource on the Node Details page of the Orion website. This can be due to a couple known causes including stale volumes that need to be purged from the database, or Application Dependency Mapping detecting connections to other nodes and their volumes.

Overview
Unrelated Volumes may be displayed within the AppStack View that is most commonly located on the Node Details page.
The unrelated volume information could come from a past bug issue with the SAM ADM feature - if enabled and running agent and connections are being showing in the "Application Connections widget."
The other way unrelated volumes can appear is when they're no longer attached to a server or the serial number of the volume changes. Once this occurs, the volume will not be automatically removed from monitoring unless on Orion Platform 2019.2 or later and have the Automatically Remove Unknown Volumes checkbox enabled. This is located in Settings > All Settings > Polling Settings.

Orion Platform
Cause
- Application Dependency Mapping (ADM) - A feature within Server & Application Monitor that detects connections to other nodes. These connections that are detected could be showing volumes attached to the nodes that connections were detected.
- Stale volumes that are in the database (volume no longer attached to server).
Resolution
First, determine if ADM is the cause. This can be determined by disabling ADM in the Application Connection Settings (Settings > All Settings > Application Connection Settings). Disable the setting globally, save changes. Check the AppStack view to see if the unrelated volumes are displayed. If they are, continue with next step.
Second, if Application Dependency Mapping/Connections are not the cause of the issue, it is likely to be stale volumes. These are volumes that once existed and are no longer responding. Orion does not automatically delete old volumes so these will need to be manually removed from the system. The quickest and most efficient way is via SQL queries.
Determine which volumes are not responding:
1. Stop the Orion services.
2. Access Database Manager (run as Admin) > Add Orion Server.
3. Right-click the Orion database > New query
4. Execute SELECT * FROM [Volumes] WHERE VolumeResponding = 'N'
5. Click enable table editing.
6. Right-click then delete the row of the stale volume.
7. Start the Orion services.
If you're affected by the second cause listed above, then you can enable the automatic removal of volumes option in the Settings > All Settings > Polling Settings menu.
