aws ec2 run-instances with offline and unallocated disks

Hi Community
We have created a new ec2 instance with 3 drives by aws ec2 run-instances as below. The 3 volumes have been created and were shown as attached in the aws console ec2 volumes screen. Nevertheless on the server in Disk Management, only Drive C: was available, the additional 2 drives were offline and unallocated: We needed to take them online, initialize and allocate by Windows tools. Does anybody know how we make them online and allocated by an aws bash command? Thanks! Patrick
