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.
NFS, FC or iSCSI?
