 "Machine already belongs to a deployment" failure when trying to onboard machines in Aria Automation

https://knowledge.broadcom.com/external/article?articleNumber=314703

Products

VMware Aria Suite

Issue/Introduction

Symptoms:
  • When attempting to onboard machines in Aria Automation you get error:

Machine [<VMNAME1>] already belongs to a deployment.
Machine [<VMNAME2>] already belongs to a deployment....

  • Under Cloud Assembly > Resources > Virtual Machines the machines do not show as 'Managed' or 'Deployed' but rather as 'Discovered' machines.
  • No Deployment appears to have them as resources in the Aria Automation UI.

Environment

  • VMware Aria Automation 8.x

Cause

This can happen if the VM is still tied to the onboarding plan and needs a cleanup.

Resolution

To resolve the issue, clean up the machine's custom properties via Rest API to ensure there are no references to a deployment:

Prerequisites:

  • You have backups of the VMware Aria Automation 8.x appliance(s).
  • You must back up all VMware Aria Automation appliances at the same time — simultaneously for all nodes.
  • If you are making the snapshots manually, you must start the snapshots of the second and third node no more than 40 seconds after you start the snapshots for the first node.
  • When you back up the VMware Aria Automation appliance, disable in-memory snapshots and enable quiescing (quiescing is a requirement only for version 8.9 and newer).

Acquire an Authentication Token:

For more information, see the Getting Your Authentication Token section in the VMware Aria Automation Programming Guide.

Procedure: Remove the stale entries using the REST API

  1. Get the compute ID of the affected machines:

    GET https://AriaAutoFQDN/deployment/api/resources?search=VM-Name001

    Note:

    • Replace AriaAutoFQDN with the FQDN of your Aria Automation environment.
    • Replace VM-Name001 with the affected VM name.
    • From the output, take the ID (e.g., 67705272-418c-30a3-9b0d-eaf2eeedb117). Use this ID as <compute_id> below.
  2. Invoke a GET API call to the following URL to see the custom properties of the machines:

    GET https://AriaAutoFQDN/provisioning/uerp/resources/compute/<compute_id>
  3. In the body of the response, search for the customProperties section of the VMs. If any of the following properties are populated with a value, remove the key-value pairs:

    Set to null for the following links:

    • descriptionLink
    • orgAuthLink
    • projectAuth
    • ownerAuthLink

    For example: descriptionLink: " "

    Edit the customProperties map to remove the following key-value pairs:

    • __composition_context_id
    • __deployment_id
    • __component_type_id
    • __blueprint_resource_id
    • __groupResourcePlacementLink
    • __relocation_origin

    Note: You must remove both the key and the value.

    Remove from tenantLinks where XXX are values specific to the machine:

    • /owner/provisioning/auth/csp/users/XXX
    • /provisioning/resources/projects/XXX
  4. Invoke a PUT API request to the same URL containing the updated request body with properties removed:

    PUT https://AriaAutoFQDN/provisioning/uerp/resources/compute/<compute_id>
  5. Attempt again to onboard the machines.

If the previous instructions do not work, proceed to Manually unregister an onboarded machine from a deployment in case of an unregister action failure as next steps.

Step-by-Step Explanation of Ballooning, Compression & Swapping in VMware

 🔹 Step-by-Step Explanation of Ballooning, Compression & Swapping in VMware ⸻ 1️⃣ Memory Ballooning (vmmemctl) Ballooning is the first memory reclamation technique used when ESXi detects memory pressure. ➤ Step-by-Step: How Ballooning Works  1. VMware Tools installs the balloon driver (vmmemctl) inside the guest OS.  2. ESXi detects low free memory on the host.  3. ESXi inflates the balloon in selected VMs.  4. Balloon driver occupies guest memory, making the OS think RAM is full.  5. Guest OS frees idle / unused pages (because it believes memory is needed).  6. ESXi reclaims those freed pages and makes them available to other VMs. Why Ballooning Happens?  • Host free memory is very low.  • ESXi wants the VM to release unused pages before resorting to swapping. Example  • Host memory: 64 GB  • VMs used: 62 GB  • Free: 2 GB → ESXi triggers ballooning  • VM1 (8 GB RAM): Balloon inflates to 2 GB → OS frees 2 GB → ESXi re...

ESXi Host Troubleshooting Checklist

  🛠️ ESXi Host Troubleshooting Checklist (With Complete Log Locations) ✅ 1. Host Status & Connectivity Check host state in vCenter (Connected / Not Responding / Disconnected) Review CPU, RAM, and datastore usage Validate HA/DRS recommendations ✅ 2. Hardware Health Monitor hardware sensors (CPU, DIMMs, fans, PSU, RAID) Check RAID controller logs via vendor tools View hardware status in: vCenter → Monitor → Hardware Health DCUI → Hardware Status ✅ 3. Network Validation Verify vSwitches, Port Groups, NIC teaming, VLAN tagging Check vmkernel ports (mgmt, vMotion, iSCSI, vSAN) Test reachability using: Shell vmkping < IP > Show more lines Validate physical NIC status and link speed ✅ 4. Storage & Datastore Checks Confirm datastore accessibility Rescan storage adapters (iSCSI/FC/NFS) Validate multipathing (Round Robin / Fixed / MRU) Check datastore latency with esxtop ✅ **5. Critical Logs & Their Locations (Full List) Here are key ESXi log files that every VMware adm...

Check service health first For vCenter Server Appliance (VCSA): Shell https : / / < vcenter - FQDN > : 5480 Show more lines Go to Services → Health to verify: vCenter Server ESXi hosts vSphere Client DNS, NTP, DB connections vpxd, vpxd-svcs, vsphere-ui B. DNS & NTP checks vCenter is highly dependent on correct DNS & time sync. Check: Shell nslookup < vcenter - fqdn > nslookup < esxi - host - fqdn > Show more lines Time drift > 5 minutes causes: Login failures vpxd crashes PSC authentication issues C. Check storage/database health Slow DB/storage = UI slow, tasks hung. For VCSA: Shell df - h du - sh / storage / log / * / var / log Show more lines Free up space if partitions hit >80%. D.
