Hi people,
I saw a recent post from a list member asking about how to finsd out what is keeping a node so busy.
No, I had a quick look at my systems and sure as eggs I have a node which is 99% bust pretty much all the time dispite not doing that mush I/O.
Example:
Node CPU_(%) *Total_Ops Total_(Bps) Latency_(us) UOW-DR-03 38 6507 178442598 4152 UOW-DR-01 40 6195 24945585 1142 UOW-DR-02 99 2618 79917069 3246 UOW-DR-04 2 0 0 0
This is just a 5 sec sample, but its pretty much like that all the time.
How do a diagnose why? Ontap 9.3P2
