IBM Spectrum Control (TPC) and STOR2RRD coexistence
STOR2RRD can coexists with IBM Spectrum Control by monitoring same SVC/Storwize storage under one condition.
Booth tools must use the same sample rate as both use the same data collection.
STOR2RRD default sample rate is 5 minutes, TPC uses 1 minute.
Only the solution seems to be switch TPC to 5 minutes.
Note that not all storages are affected by that.
Especially big SVC clusters (4 - 8 nodes) do not work in STOR2RRD when TPC uses 1 minute sample rate.
You migh see every 5 minutes these errors in /home/stor2rrd/stor2rrd/logs/error.log-<storage name>

Here you can find out actual sample rate frequency on the storage, it must report 5 minutes!
