Dear Uehara,  These parameters should not be changed unless advised otherwise by EMC Support, hence there is no command to change any particular ones - changing performance profiles will change them all to the tested and recommended values for a particular profile.  Many thanks, Pawel
There are lots of ScaleIO performance parameters as written in CHAPTER 5 of EMC ScaleIO 2.0.x Performance Fine-Tuning Technical Notes. (e.g. mdm_number_sds_receive_umt, sds_number_network_umt) I could find how to change the values by changing its profile from Default to High Performance (and vise versa) but could not find how to change its each performance parameter. If anybody know how to change it, please let me know!
How to set up each performance parameter?
