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>
