A response code of 400 in the context of RESTful API operations generally indicates that the request

made by the client was malformed or contains a syntax error. This means that the data stream sent

by the client to the server did not follow the rules as defined by the API specification. It could be due

to various reasons such as incorrect request format, missing required parameters, or invalid

parameter values1.

In the case of the Dell XtremIO environment, if a customer receives a 400 response code when

attempting to create a volume via the RESTful API, it is likely due to a syntax error in the API

command. The customer should review the API request to ensure that it conforms to the expected

format and includes all necessary information as per the XtremIO API documentation2.

Reference:

Community discussions on the Dell Technologies website where similar issues have been addressed

and the cause of the 400 error was identified as a syntax error in the RESTful API command2.
