When the OS is up running, verify that NVDIMM-Ns are populated correctly.

Identify whether NVDIMM-Ns appear as /dev/pmem0, /dev/pmem1, .. /dev/pmemN, where N is a natural number.
# ls /dev/pmem*
Check the size of NVDIMM-N devices /dev/pmem0 to /dev/pmemN
# lsblk
Create xfs file system for all pmemN devices
# mkfs.xfs /dev/pmem0 
Create directories on all nvdimmN
# mkdir –p /mnt/nvdimm0 
# mount –t xfs –o dax /dev/pmem0 /mnt/nvdimm0
Save the mount point and option so that devices are mounted on next reboot.
# echo "/dev/pmem0 /mnt/nvdimm0 xfs dax 0 0" >> /etc/fstab

Write or copy files onto /mnt/nvdimm0

# echo “writing into nvdimm” >> /mnt/nvdimm0/write.txt
