Step 2
Run the following command to query basic information about the SSD controller (such as
nvme0):
hioadm info -d nvme0
The command output is similar to the following:
[root@localhost tool]# hioadm info -d nvme0
Namespace<1> size: 1.6TB, 1600321314816Byte

Step 3
Run the following command to query the SMART information of the SSD controller (such as
nvme0):
hioadm info -d nvme0 –s
The command output is similar to the following:
[root@localhost tool]# hioadm info -d nvme0 -s
