Hello,
We are experiencing some performance issues with data hosted on an aggregate that virtualizes a 3rd party array. After working with NetApp support, the conclusion was that the disk from the 3rd party array is not keeping up. That prompted the opening of a case with EMC. EMC quickly found that SPA on the EMC array is being far more utilized than SPB. They recommended balancing the load between service processors.
As far as I can tell, there is no way to manually configure our v3240 to use specific paths to 3rd party storage. Is this true? If not, how would I go about configuring our v3240 to use a path to a 3rd party LUN via SPB versus SPA?
You can see from the output of storage show disk -p and aggr status -r that we are overutilizing the path through sanswitch1, port 3/10 which goes to SPA. I'd like to swap the primary path with the secondary path so more LUNs will be accessed through sanswitch0, port 5/7 which goes to SPB.
# ssh filer storage show disk -p
PRIMARY PORT SECONDARY PORT SHELF BAY
