3.3 Deleting a virtual drive (VD) by using Redfish 2016

VDs can also be deleted by using Redfish 2016 standard storage API. By using a selected VD URI of form

“redfish/v1/Systems/System.Embedded.1/Storage/Volumes/{virtual disk instance id}”, with no payload

required, use a DELETE command to delete the VD.

Here is an example, taken from the “DeleteVirtualDiskRedfish.py” script, of the form of the URI and DELETE

command for deleting VD from Python GitHub script.

url = 'https://%s/redfish/v1/Systems/System.Embedded.1/Storage/Volumes/%s' %

(idrac_ip, virtual_disk)

headers = {'content-type': 'application/json'}

response = requests.delete(url, headers=headers,

verify=False,auth=(idrac_username,idrac_password))

The following example uses the “DeleteVirtualDiskRedfish.py” script from the Dell EMC Redfish Scripting

Github repository to delete a RAID 0 VD:

1. Check for VDs detected on the target server.

C:\Python27>DeleteVirtualDiskRedfish.py -ip 192.168.0.130 -u root -p calvin -v

RAID.Slot.6-1

- Supported virtual disk(s) detected to delete for controller RAID.Slot.6-1 -

Disk.Virtual.0:RAID.Slot.6-1, Volume Type: NonRedundant

2. Using the VD instance ID, perform the VD delete operation.

C:\Python27>DeleteVirtualDiskRedfish.py –ip 192.168.0.130 -u root -p calvin -D

Disk.Virtual.0:RAID.Slot.6-1
