SHARPv2 must be running (enable_SHARP = true) and the NVIDIA Scalable Hierarchical Aggregation and Reduction Protocol (SHARP)™ allocation parameter must be enabled (enable_SHARP_alloction = true) for this API to trigger resource (GUID) allocations and deallocations within SHARP.
NVIDIA SHARP reservation REST APIs support the following operations:
Get All Reservations
Description – Retrieves all SHARP reservations
Request URL – GET /ufmRest/app/sharp/allocate_resources
Request Content-Type – Application/json
Response
{ "anas1":{ "pkey":"0x12", "guids":["0x248a0703008a850a", "0x248a0703008a850b"] }, "anas2":{ "pkey":"0x12", "guids": ["0xf452140300383a01", "0xf452140300383a02"] } }
Status Codes
200 – OK
400 – BAD_REQUEST
Get Specific SHARP Reservation
Description – Gets specific SHARP reservation by app_id
Request URL – GET /ufmRest/app/sharp/allocate_resources/<app_id>
Request Content Type – Application/json
Status Codes

"anas1":{

}
}
Create a New SHARP Reservation
The following API is replacing the deprecated SHARP API presented in earlier versions of this UFM Enterprise REST API Guide.
Description – Creates a new SHARP reservation. By default, the SHARP blocking API is called, which entails sending the reservation request to SHARP and awaiting the response (success or fail). To revert to the previous behavior of using the non-blocking API, set the "blocking" parameter in the API to false. If the partial allocation parameter is set to false, the SHARP allocation request will not succeed in the event that even a single node is absent in the fabric. By default, this parameter is set to true.
Example of a false partial allocation: Request URL – POST /ufmRest/app/sharp/resources?partially_alloc=false
Example of calling a non-blocking API: Request URL – POST /ufmRest/app/sharp/resources?blocking=false
Request Content-Type – Application/json
Status Codes
202 – ACCEPTED (All nodes were added successfully to created allocation)
206 – PARTIAL (Not all nodes were added to created allocation because they are not found in the fabric)
200 - OK (All nodes were added successfully to the created allocation and the SHARP blocking API is called)
400 – BAD_REQUEST

Delete SHARP Reservation
The following API is replacing the deprecated SHARP API presented in earlier versions of the UFM Enterprise REST API Guide.
Description - Deletes SHARP Allocation. By default, the SHARP blocking API is called to delete SHARP reservation.
Example of calling delete allocation using SHARP blocking API: Request URL - DELETE /ufmRest/app/sharp/resources/<app_id>
Example of calling delete allocation using SHARP non-blocking API: Request URL - DELETE /ufmRest/app/sharp/resources/<app_id>?blocking=false
