Has any experienced to following especially with a VMware environment.

The storage system is tugging along happily and then you get High request for resources, resulting in CPU and Disk going about 90%. This isn’t my question.

My question is; within the  VMware environment you get High Latency, then  “Dead Path” and in the vmkernel.log high “WORLD” counters, this is normally resolved via a reboot of the VMhost, after the APD the NetApp resources go backdown to 0% until the next peak.

Is the above considered normal, with high utilization systems,  if not what should the behaviour be?

OnTap is 8.2.1P2 7-Mode.
