Work with EBS volumes

Every Amazon Elastic Compute Cloud (EC2) instance you create contains a root Amazon Elastic Block Store (EBS) volume. The root volume on Microsoft Windows is the C: drive.

You can attach additional EBS volumes to EC2 instances once deployed.

Set EBS volume size on creation

When you use ArcGIS Enterprise Cloud Builder for Amazon Web Services, the sample Amazon Web Services (AWS) CloudFormation templates provided by Esri, or AWS Management Console to deploy a site, you can set the size of the root volume for your instances when you create them.

Add an EBS volume

If you have an EBS volume that contains data you want to access from an ArcGIS Enterprise instance on AWS, you can add the volume to the instance using one of the following methods:

• If you deploy ArcGIS Enterprise using CloudFormation templates provided by Esri, you can specify an existing EBS volume to add to the deployment.
• If you do not use CloudFormation templates provided by Esri to deploy EC2 instances or to add an EBS volume to an instance after you create it, use the AWS Management Console. See the Amazon Elastic Compute Cloud documentation for attaching EBS volumes to a Windows or Linux instance.

Modify or move an EBS volume

If you have an EBS volume on your EC2 instance in addition to the root volume, you can alter the volume to increase the volume size or move the volume to another instance to transfer data. To accomplish this, use an AWS EC2 snapshot and AWS Management Console.

Follow these steps to create a snapshot to increase volume size or move a volume:

1. Connect to your instances on AWS and stop ArcGIS Server, Portal for ArcGIS, and ArcGIS Data Store if they are running.
2. Stop other services that have data folders on the EBS volume.
3. In the EC2 console in AWS Management Console, locate the EBS volume you want to modify or move, and create a snapshot of this volume using AWS tools.
4. Locate the newly created snapshot and create a volume from it.

   You can define the size of the volume when you create it.

5. If you created the snapshot to increase the volume size, you must remove the existing EBS volume from the instance.

   Take note of the mapping of the existing volume before you remove it, because you must map the larger volume to the same drive.

6. If you created the snapshot to move a volume, repeat steps 1 through 3 on the target instance.
7. Attach the newly created volume to the target instance.

   If you're replacing the EBS volume, ensure the disk mapping matches that of the volume you removed.

8. Start services that have data folders on the EBS volume you replaced.
9. Start the database instances.
10. Start ArcGIS software services.
11. If you no longer need the detached data volume or the snapshot you created, delete them using tools in AWS Management Console.
