Listing Attachments for a Boot Volume

Learn how to list attachments for a boot volume.

When a boot volume has no attached instances, then either the boot volume was detached from the associated instance or the instance was terminated (while the boot volume was preserved).

Required IAM Policy

To use Oracle Cloud Infrastructure, an administrator must be a member of a group granted security access in a policy  by a tenancy administrator. This access is required whether you're using the Console or the REST API with an SDK, CLI, or other tool. If you get a message that you don't have permission or are unauthorized, verify with the tenancy administrator what type of access you have and which compartment  your access works in.

For administrators: The policy in Let users launch compute instances includes the ability to list volume attachments. The policy in Let volume admins manage block volumes, backups, and volume groups lets the specified group do everything with block volumes and backups, but not launch instances.

If you're new to policies, see Managing Identity Domains and Common Policies. For reference material about writing policies for instances, cloud networks, or other Core Services API resources, see Details for the Core Services.
    1. On the Boot Volumes list page, select the boot volume that you want. If you need help finding the list page or the boot volumes, see Listing Boot Volumes.
    2. Select Attached instances.

  • Use the oci compute boot-volume-attachment list command and specify the --availabilty-domain and --compartment-idparameters to view the boot volumes in that availability domain and compartment:

    oci compute boot-volume-attachment list

    For a complete list of parameters and values for CLI commands, see the CLI Command Reference.

  • Run the ListBootVolumeAttachments operation and specify the availabilityDomain and compartmentId attributes to list boot volume attachments in a compartment.
