AWS EBS volume not showing up windows disk management

Question

I created an EC2 Windows instance with gp2 EBS volume.

But on logging into the windows system and checking on Disk Management, I don't find the added volume space under both un-allocated or primary partition.

I created the instance using an AWS launch template and the Device name of EBS was given as xvda.

What am I missing here?

Answer 1

Changing the name of EBS from xvda to xvdd in ec2 launch template and creating a new instance solved the issue.

Seems like any EBS Device name above C alphabetically is not shown in Disk Management, which is weird.

For those who cannot create a new instance, create a new volume from EBS volume and attach it to instance manually and restart the windows machine. Then it would come up in the Disk management.

AWS now note that:

Recommended device names for Windows: /dev/sda1 for root volume. xvd[f-p] for data volumes.

i.e. for windows EC2 EBS (non root) volumes choose from the list of "Device Name"s a name that

• starts with xvd
• ends with a letter from f to p
