3.8 Limitations when using Redfish 2016 standard storage APIs for
storage configuration
There are several limitations on job workflows when using Redfish 2016 standard APIs for storage
configurations:
 Stacking multiple storage configuration operations and running them within a single iDRAC job is not
supported. For example, a certain storage management task might require the deletion of a virtual
disk followed immediately by the creation of a new VD. While the user may want to perform both
steps in a single iDRAC job, this is not possible under the current Redfish standard. These steps
must be performed by separate steps, using one job to delete the virtual disk and a second job to
create the new virtual disk with each job being monitored for completion before initiating another job
 Creating multiple sliced RAID volumes within a single job is also not supported. For example, a
storage management task might require the creation of sixteen 2G RAID 0 virtual disks; this is not
possible using a single iDRAC job within the current Redfish standard. The current storage APIs
require that only a single sliced RAID virtual disk be created within an iDRAC job, the job be
monitored for completion and the balance of virtual disks be created by repeating these steps.
3.9 Benefits of using the Dell EMC Server Configuration Profile feature
For certain storage management tasks, the Dell EMC Server Configuration Profile (SCP) feature can greatly
simplify operations:
 Multiple storage management operations can be stacked within a single SCP import operation. For
example, an SCP file, imported via a single iDRAC RESTful API call, can reset a PERC controller,
create multiple virtual disks, initialize the virtual disks, set an encryption key, and lock the virtual
disks, all performed via a single iDRAC job
 A range of PERC controller features are supported using an SCP which are not currently supported
by Redfish 2016 standard storage APIs. These features include:
 Converting disks between non-RAID / RAID state
 Changing or removing a controller encryption key
 Locking a RAID volume
 Assigning / Un-assigning global or dedicated hot spares
