Using smartctl to get vendor specific Attributes from ssd drive behind a SmartArray P410 controller
- by Lairsdragon
Recently I have deployed some HP server with SSD's behind a SmartArray P410 controller. While not official supported from HP the server work well sofar.
Now I like to get wear level info's, error statistics etc from the drive. While the SA P410 supports a passthru of the SMART Command to a single drive in the array the output I was not able to the the interesting things from the drive.
In this case especially the value the Wear level indicator is from interest for me (Attr.ID 233), but this is ony present if the drive is directly attanched to a SATA Controller.
smartctl on directly connected ssd:
# smartctl -A /dev/sda

Do I hunt here a bug, or is this a limitation of the p410 SMART cmd Passthru?
