If not created already, create an instance of Rest or Redfish Object using the RestObject or RedfishObject class respectively. The class constructor takes iLO hostname/ ip address, iLO login username and password as arguments. The class also initializes a login session, gets systems resources and message registries.

Rest Object creation:

REST_OBJ = RestObject(iLO_host, login_account, login_password)

:

Redfish Object creation:

REDFISH_OBJ = RedfishObject(iLO_host, login_account, login_password)

:

The method ex44_get_LogicalDrives takes an instance of rest object ( or redfish object if using Redfish API ) as argument.

def ex44_get_LogicalDrives(restobj):

:

Find and get the system resource for HpSmartStorageArrayController.

instances = restobj.search_for_type("HpSmartStorageArrayController.")

:

Send HTTP GET request to the system URI(s).

for instance in instances:
    response = restobj.rest_get(instance["href"])

:

For each system print array controllers from the response body. Return an error if not available.

if "ArrayControllers" in response.dict:
    sys.stdout.write("\tArrayControllers:  " +
                   str(response.dict["ArrayControllers"]) + "\n")
else:
    sys.stderr.write("\tArrayControllers is not " \
                "available on HpSmartStorageArrayController resource\n")
