Environment

VMware HCX 4.11.x with multiple Single Site OSAM Service-Mesh's.

Cause

• SdrVMID is selected in a "first-in-line" basis.
• In a deployment with multiple Single Site OSAM SM's the first SDR VMID is chosen.
• In the "JobData" output shown above: the correct SRG appliance is shown. 
  

  "sgwApplianceId": "########-####-####-####-f2c933ca11f6",
          "sentinelVersion": "4.11.0.0.24448058",
          "sgwApplianceName": "<SM name>-SRG-I1",  

• The vm-id can be found by going to this SRG VM in VC inventory and looking at the URL:
  
  
  

Resolution

WORKAROUND:

• Operate with only 1 single site OSAM SM.
• This will be resolved in an upcoming release of HCX.
