How to Describe Volumes and Instances

After creating Amazon EBS volumes and attaching them to instances, you should verify they are available.

AWS Management Console

To view information about an Amazon EBS volume

  1. Log in to the AWS Management Console and click the Amazon EC2 tab.

  2. Click Volumes in the Navigation pane.

    The console displays a list of current volumes and the instances to which they are attached.

  3. To view more information about a volume, select it.

    Information about the volume appears in the lower pane.

Command Line Tools

To describe volumes, which lists information about all volumes that you own

  • Enter the following command.

                  PROMPT> 
              
                 
              
              ec2-describe-volumes

    Amazon EBS returns the following information.

    VOLUME vol-4d826724 us-east-1a 800 in-use 2008-02-14T00:00:00+0000
  ATTACHMENT vol-4d826724 i-6058a509 /dev/sdh attached 2008-02-14T00:00:17+0000
  VOLUME vol-50957039 13 us-east-1a available 2008-02-091T00:00:00+0000
  VOLUME vol-6682670f 1 us-east-1a in-use 2008-02-11T12:00:00+0000
  ATTACHMENT vol-6682670f i-69a54000 /dev/sdh attached 2008-02-11T13:56:00+0000

    This information includes the volume ID, capacity, status (in-use or available) and creation time of each volume. If the volume is attached, an attachment line shows the volume ID, the instance ID to which the volume is attached, the device name exposed to the instance, its status (attaching, attached, detaching, detached), and when it attached.
