Creating a Volume Group

Create a volume group in the Block Volume service.

1. Open the navigation menu and select Storage. Under Block Storage, select Volume Groups.
2. Click Create volume group.
3. On the Basic information page, enter a user-friendly name or description. Avoid entering confidential information.
4. Select the compartment that you want to store the volume group in.
5. Select the availability domain for the volume group.
6. (Optional) Click Show Tagging Options to add tags to the volume group.
  If you have permissions to create a resource, then 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're not sure whether to apply tags, skip this option or ask an administrator. You can apply tags later.
7. Click Next.
8. On the Add volumes page, add each volume that you want. After adding volumes, click Next.
  
  Click + Additional Volume.
  
  Select the compartment that contains the volume that you want.
  
  Select the volume that you want.
  
  Note
  
  For both block volumes and boot volumes:
  
  You can't add a volume with an existing backup policy assignment to a volume group with a backup policy assignment. Remove the backup policy assignment from the volume before you add it to the volume group.
  
  If any of the volumes you add to the group are configured for replication, the destination region configured for them must match the destination region you configure for the volume group. See Limitations and Considerations.
9. (Optional) On the Cross region replication page, enable asynchronous cross region replication for the volume group, and then click Next.
  If you enable cross-region replication, you can encrypt the volume group replica in the destination region with your own Vault encryption key by selecting Encrypt using customer-managed keys for Cross region replication encryption. If you select this option, you must specify the OCID for a valid encryption key in the destination region, for more information, see Requirements for Customer-Managed Encryption Keys for Cross-Region Operations.
  
  If any of the volumes you add to the group are configured for replication, the destination region configured for them must match the destination region you configure for the volume group, see Limitations and Considerations.
10. (Optional) On the Backup policies page, select a backup policy to configure schedule backups for the volume group, and then click Next.
  If you select a backup policy enabled for cross region backup copies you can encrypt the volume group backup copy in the destination region with your own Vault encryption key by selecting Encrypt using customer-managed keys for Cross region backup copy encryption. If you select this option, you must specify the OCID for a valid encryption key in the destination region, see Requirements for Customer-Managed Encryption Keys for Cross-Region Operations for more information.
  
  For more information, see Policy-Based Volume Group Backups.
11. On the Summary page, review the information to confirm that it's correct.
12. Click Create.

Use the oci bv volume-group create command and required parameters to create a volume group from existing volumes:

oci bv volume-group create --compartment-id <compartment_ID> --availability-domain <external_AD> --source-details <Source_details_JSON>

Volume lifecycle status must be AVAILABLE to add it to a volume group.

For example:

oci bv volume-group create --compartment-id ocid1.compartment.oc1..<unique_ID> --availability-domain ABbv:PHX-AD-1 --source-details '{"type": "volumeIds", "volumeIds":["ocid1.volume.oc1.phx.<unique_ID_1>", "ocid1.volume.oc1.phx.<unique_ID_2>"]}'

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

Run the CreateVolumeGroup operation to create a volume group.
