Creating a Volume

You can create a volume using Block Volume.

Required IAM Policy

To use Oracle Cloud Infrastructure, you must be given the required type of access in a An IAM document that specifies who has what type of access to your resources. It is used in different ways: to mean an individual statement written in the policy language; to mean a collection of statements in a single, named "policy" document (which has an Oracle Cloud ID (OCID) assigned to it); and to mean the overall body of policies your organization uses to control access to resources. written by an administrator, whether you're using the Console or the REST API with an SDK, CLI, or other tool. If you try to perform an action and get a message that you don’t have permission or are unauthorized, confirm with your administrator the type of access you've been granted and which A collection of related resources that can be accessed only by certain groups that have been given permission by an administrator in your organization. you should work in.

For administrators: The policy in Let volume admins manage block volumes and backups lets the specified group do everything with block volumes and backups.

If you're new to policies, see Getting Started with Policies and Common Policies. If you want to dig deeper into writing policies for instances, cloud networks, or other Core Services API resources, see Details for the Core Services.

Tagging Resources

You can apply tags to your resources to help you organize them according to your business needs. You can apply tags at the time you create a resource, or you can update the resource later with the desired tags. For general information about applying tags, see Resource Tags.

Using the Console

  1. Open the navigation menu. Under Core Infrastructure, go to Block Storage and click Block Volumes.
  2. Click Create Block Volume.
  3. Fill in the required volume information:
    • Name: A user-friendly name or description.
    • Domain: Must be in the same availability domain as the instance.
    • Size: Must be between 50 GB and 32 TB. You can choose in 1 GB increments within this range. The default is 1024 GB. If you choose a size outside of your service limit, you may be prompted to request an increase. For more information, see Service Limits.
    • Backup Policy: Select the appropriate backup policy for your requirements. See Policy-Based Backups for more information about backup policies. If you only require on-demand manual backups, select None.
    • Tags: Optionally, you can apply tags. If you have permissions to create a resource, you also have permissions to apply free-form tags to that resource. To apply a defined tag, you must have permissions to use the tag namespace. For more information about tagging, see Resource Tags. If you are not sure if you should apply tags, skip this option (you can apply tags later) or ask your administrator.
    • Encryption: Optionally, you can encrypt the data in this volume using your own Key Management encryption key. To use Key Management for your encryption needs, select the Encrypt using Key Management check box. Then, select the Vault Compartment and Vault that contain the master encryption key you want to use. Also select the Master Encryption Key Compartment and Master Encryption Key. For more information about encryption, see Overview of Key Management.

  4. Click Create Block Volume.

    The volume will be ready to attach once its icon no longer lists it as PROVISIONING in the volume list. For more information, see Attaching a Volume.

Using the API

To create a volume, use the following operation:

For information about using the API and signing requests, see REST APIs and Security Credentials. For information about SDKs, see Software Development Kits and Command Line Interface.
