CentOS* is not on the list of supported Linux* distributions for the Intel® SSD Data Center Tool.
However, in order to provide the best support possible we will download the latest release of CentOS* and test it in our lab. We will let you know how this turns out.
Additionally, we'll like to have some more information:
- What is the model of the Intel® Solid State Drive(s) you're working with?
- Do you get errors when you run any other commands?
We tested the Intel® SSD Data Center Tool with CentOS* 7 in our lab yesterday, but were unable to reproduce your issue.
Our recommendation in this case would be to remove ISDCT*, https://downloadcenter.intel.com/download/26221/Intel-SSD-Data-Center-Tool download a fresh copy and reinstall.
Please let us know whether this resolves your issue.
