Bug Description
During high load situations where multiple requests for volume creation/attachment and volume deletion/detachment are happening errors can occur.
This is being caused by the locks the 3PAR FC and iSCSI drivers have in place. By removing the locks and having separate connections for each volume request the problem can be avoided.
Example of an error that occurs under high load:
2014-10-14 11:44:09.900 ERROR oslo.messaging.
Bad or unexpected response from the storage volume backend API: Failure in clear_volume_
