Example Redfish REST calls: Create RAID volume

Prerequisites:

  • PowerEdge Gen 14 server (R740, M640, etc)
  • iDRAC 9 with firmware version: 3.21.21.21 or above

Create RAID volume (virtual disk)

Method: POST

URI: https://<idrac ip>/redfish/v1/Systems/System.Embedded.1/Storage/<CONTROLLER>/Volumes

BODY / Payload:

The following is an example of creating a RAID1 (mirror) volume on the RAID.Slot.6-1 controller using two disks (bay 2 and bay 3):

{
    "VolumeType": "Mirrored",
    "Name": "VOL02-R1",
    "Drives": [
        {
            "@odata.id": "/redfish/v1/Systems/System.Embedded.1/Storage/Drives/Disk.Bay.2:Enclosure.Internal.0-1:RAID.Slot.6-1"
        },
        {
            "@odata.id": "/redfish/v1/Systems/System.Embedded.1/Storage/Drives/Disk.Bay.3:Enclosure.Internal.0-1:RAID.Slot.6-1"
        }
    ]
}

For RAID1 the VolumeType is “Mirrored”. For other RAID types please use the below:

  • RAID 0: “NonRedundant”
  • RAID 1: “Mirrored”
  • RAID 5: “StripedWithParity”
  • RAID 10: “SpannedMirrors”
  • RAID 50: “SpannedStripesWithParity”

HTTP status 202 will be returned if creation is successful.
