The EqualLogic driver uses an SSH connection to the PS array to perform CLI operations. The maximum number of SSH sessions (7) supported makes limitation on provisioning multiple number of VM at the same time. The while loop in ssh getoutput becomes a deadlock and consumes all CPU resources. It seems that we should check the SSH session availability before entering the While loop.
Error: Number of open cli sessions reached maximum allowed value of 7 |

The cinder-volume service goes down and CPU utilization is at 100%. The root cause is due to the while loop in ssh getoutput routine which becomes a deadlock and consumes all CPU resources. It seems that we should check the SSH session availability before entering the While loop.
