My experience, hope thats correct. If you try to refresh a storage (vsp for example) and you did not see „Refresh Performance Data“ you have a small thing to do. Setup */HiCommand/HiCommandServer/config/tuningmanager.properties that it fits your environment
- the number of cooperating Tuning Manager servers
htnm.servers=1- the information(host name and port number) on the cooperating Tuning Manager server
htnm.server.0.host=YOURSERVERIP
htnm.server.0.protocol=http
htnm.server.0.port=23015- restart all services
After that you have, if everything is correct, the Refresh-Option AND you can see „IOPS“ inside the „Mobility-Tab“ -> „DP-Pools“
