PowerMax_2000 rest API ReadTimeout issue.
Hi Team,
We are using PowerMax_2000 with Unisphere version V9.2.3.15 and openstack volume driver VMaxRestProductDriver (4.4.0).
While creating multiple volumes requests with above configuration, we are seeing ReadTimeout issue intermittently during invocation of Powermax Rest API's as shown below. Do you have any know issue of read timeout with PowerMax.
|__Flow 'volume_create_manager': requests.exceptions.ReadTimeout: The GET to Unisphere server httpspvc://9.3.118.149:8443/univmax/restapi has experienced a ReadTimeout error. Please check your Unisphere server connection/availability. Exception message: None: None

Do you have a Service Request open for this issue? If so, please provide the number so we can review the details.
I would recommend enabling INFO and RESTAPI logging on your Unisphere server and having support review these logs for any additional insight.
