After research, all commands to view ssd, as long as they pass RAID, need to use MegaCli and smartCtl to obtain the usage of SSD disk. After careful study, I am currently using.
The RAID cards are LSI logic/symbioslogic megaraid SAS1078 and 2 108. Use common MegaCli query:
This is the download address:
Mega CLI 5 of Centos
Mega CLI 6 of Centos
The whole process is divided into two steps. Step one, get the information of the subsequent hard disk from the RAID card. Next, smartCtl is used to display the details of the hard disk.
Use MegaCli to get hard disk information under RAID card:
Then use the following command:
/opt/mega raid/mega CLI/mega CLI 64-PD list-aALL
This can find out the contents under the RAID card. It will appear as follows:
Cabinet equipment ID: 252
Slot number: 7
Device Id: 28
Serial number: 2
Media error count: 0
Other error count: 1

Last Forecast Failure Event Sequence Number: 0
