Map non-NVMe disks on Amazon EC2 Windows instance to volumes
For instances launched from a Windows AMI that uses Amazon PV or Citrix PV drivers, you can use the relationships described on this page to map your Windows disks to your instance store and EBS volumes. This topic explains how to view the non-NVMe disks that are available to the Windows operating system on your instance. It also shows how to map those non-NVMe disks to the underlying Amazon EBS volumes and the device names specified for the block device mappings used by Amazon EC2.
Note
If you launch an instance If your Windows AMI uses Red Hat PV drivers, you can update your instance to use the Citrix drivers. For more information, see Upgrade PV drivers on EC2 Windows instances.
List non-NVMe disks
You can find the disks on your Windows instance using Disk Management or PowerShell.
Map non-NVMe disks to volumes
The block device driver for the instance assigns the actual volume names when mounting volumes.
Instance store volumes
The following table describes how the Citrix PV and Amazon PV drivers map non-NVMe instance store volumes to Windows volumes. The number of available instance store volumes is determined by the instance type. For more information, see Instance store volume limits for EC2 instances.
