AWS SSM 发送命令来分离 EBS 存储？

Question

I was trying to detach EBS storage from a Windows EC2 instance using SSM send-command with a target filter named EC2. Example:

aws ssm send-command --targets "Key=tag:Name,Values=MYWINDOWSServer" --document-name "AWS-RunShellScript" --parameter "commands = aws ec2 detach-volume --volume-id vol-00000xxxae64a1bd"

The tag name is unique so it should only be executing on 1 server in this account. The output I am getting is confusing and I can't get this working. Can someone point me in the right direction? Thanks in advance.

Output:

This is the output of the ssm command that you ran. Once you run the SSM command it status is changed to pending and once the command gets completed it's status changes to success/failed/timed out depending on the outcome.

"Status": "Pending"

Similary, the output you see are all the argumets that return when you run a SSM command. Since this is in command line it is a bit over-whelming.

I would suggest you to look for this from SSM console in the Run command history. Look for the command ID: 934abae5-d28e-49f8-a5a8-a9a9f64c62cc

You will get to know if it completed or failed.
