Execute the following requests to get information of Virtual Guest/Hardware already provisioned:

Virtual Guest:

https://[username]:[apikey]@api.softlayer.com/rest/v3/SoftLayer_Virtual_Guest/[VSI_id]/getObject?objectMask=mask[id,fullyQualifiedDomainName,createDate,provisionDate,activeTransaction,activeTransactionCount,status]

Method: GET

Hardware:

https://[username]:[apikey @api.softlayer.com/rest/v3/SoftLayer_Hardware/[Hardware_id]/getObject?objectMask=mask[id,fullyQualifiedDomainName,provisionDate,hardwareStatus,lastTransaction]

Method: GET

https://[username]:[apikey @api.softlayer.com/rest/v3/SoftLayer_Hardware_Server/[Hardware_id]/getObject?objectMask=mask[id,fullyQualifiedDomainName,provisionDate,activeTransaction,activeTransactionCount,hardwareStatus]

Where:

To know that a Server is already provisioned, please review that:

“activeTransaction” is NULL, or
“provisionDate” has a value different to NULL (i.e. when the VSI is ready, the provisionDate will have the respective provisionDate)
The “status” is Active

To get VSI/Hardware ids, please review:
