Running a FailoverTest from Powershell?

I’m trying to run a FailoverTest of a VPG through the RESTful API from Powershell and hitting problems

I’m creating authentication headers OK, querying a list of VPGs, looping through to find the VpgIdentifer of the required VPG OK and then returning a list of Checkpoints for the required VPG. I select the latest one to create the Request Body before issuing an Invoke-RESTMethod along the lines of below: –

$testFailoverURI = “https://myzvm.mydomain.com:9669/v1/vpgs/1a1aaaaa-a1a1-1aa1-a1a1-a111111a11aa/FailoverTest”;

$contentType = “application/json”;

$failoverTestBody = ‘{“CheckpointId”: “1111111”}’

$testFailover = Invoke-RestMethod -Uri $testFailoverURI -Method Post -Headers $zvmSessionHeader -Body $failoverTestBody -ContentType $contentType;

but am getting the error: –

Invoke-RestMethod : {“Message”:”Exception occured in API : FailoverTest is not allowed due to below VraActivities:Vra on Host 111aa1a1-a1a1-11aa-11a1-a1a11111111a.host-11111 is not tracked “}

Any help/guidance would be much appreciated.

Thanks in advance,
