I am in the process of building healthcheck for our various linux machines (DELL, HP etc) and trying to utilize some of the standard tools to expose physical disk health state. I am a noob on smartctl and trying to understand how it can help here.
I am encountering exit 4 running smartctl against my DELL machines on megaraid devices. Checking the man page for this return code, it states: “Bit 2: Some SMART or other ATA command to the disk failed, or there was a checksum error in a SMART data structure (see '-b' option above)”
I am assuming the failure here is because of the “ATA return descriptor not supported by controller firmware”?
Has anyone experienced this and how to overcome it?
