This article applies to This article does not apply to This article is not tied to any specific product. Not all product versions are identified in this article.

Cause

The library libpmem was removed from the SDS node or not installed.
Checking for the lipmem package returns nothing.
#rpm -qa | grep libpmem*



The SDS uses this library to interact with the NVDIMMs.
This explains why the SDS service was unable to read the NVDIMMs.

Resolution

Install the libpmem on the SDS.
After the package is installed, reboot the SDS.
After the SDS comes back up, you can add the dax device to the SDS.

In this example the version is: libpmem-1.5.1-2.1.el7.x86_64
