redfish_storage_volume (Resource)

This Terraform resource is used to configure virtual disks on the iDRAC Server. We can Create, Read, Update, Delete the virtual disks using this resource.

Note: capacity_bytes and volume_type attributes cannot be updated.

Import

Note: Odata ID of all available volumes on a storage controller can be fetched by running the following GET request on the iDRAC “/redfish/v1/Systems/System.Embedded.1/Storage//Volumes/” Eg. redfish/v1/Systems/System.Embedded.1/Storage/RAID.Integrated.1-1/Volumes/ The ID of any storage controller on the iDRAC, in turn, can be fetched using the “redfish_storage” data source

Import is supported using the following syntax:

terraform import redfish_storage_volume.volume "{\"id\":\"<odata id of the volume>\",\"username\":\"<username>\",\"password\":\"<password>\",\"endpoint\":\"<endpoint>\",\"ssl_insecure\":<true/false>}"
  1. This will import the storage volume instance with specified ID into your Terraform state.
  2. After successful import, you can run terraform state list to ensure the resource has been imported successfully.
  3. Now, you can fill in the resource block with the appropriate arguments and settings that match the imported resource’s real-world configuration.
  4. Execute terraform plan to see if your configuration and the imported resource are in sync. Make adjustments if needed.
  5. Finally, execute terraform apply to bring the resource fully under Terraform’s management.
  6. Now, the resource which was not part of terraform became part of Terraform managed infrastructure.
