Thanks for your response, Christian.

>> smartctl -r ioctl,2 -i -H -d sat+megaraid,9 /dev/bus/0
Attaching the output. smart status check returned -1.

sat_device::ata_pass_through: scsi_pass_through() failed, errno=38 [ATA

>>None of the specs or previous sample outputs from Micron RealSSDs include
attribute 190.
What is the best way out in these cases to detect the health status of the
disks? Is there a flag or something to detect the value type (normalized vs

thanks,
Janny
