Verify EC2 Instance Status
Amazon EC2 servers have a control system to determine if the OS is running and responsive. That’s called Instance Status Check. The following script can be used to determine if all servers that have been converted to EC2 successfully and have booted and are responsive.
1. On the Migration Factory console, select Jobs on the left hand side menu, and select Actions, and then Run Automation on the right hand side
2. Enter Job Name, select 3-Verify Instance Status Script and automation-server.WORKGROUP as your automation server to run the script. Select Wave 1 and finally select Submit Automation Job
3. You will be redirected to the Job list page, the job status should be running, and you can click refresh button after about 1 minute to see the status.
As an alternative to check real time status, you can login to AWS Console, switch to AWS Application Migration Service. Select Launch History on the left hand side, you can see the real time job status, you need to wait for the status to change to Completed.
The Target instance might take up to 30 minutes to complete conversion and change the status to 2/2 Passed, you might not see status update from the scripts until the replication is complete. If the job failed with do not have a target instance, wait for 5 minutes and try again. This error means MGN job is still in progress, target instance hasn’t been created yet
4. Finally, job will be completed. Job status should change to COMPLETE, and you can see the details in the Log section
5. Migration factory should have also received status update from the script. If necessary, refresh screen.
