Smartctl Open Device Dev Sda Failed Dell Or Megaraid Controller Please Try Adding 39d Megaraid N 39 Extra: Quality [updated]

If you want, I can produce:

for N in $(seq 0 $((MAX_DISKS-1))); do echo "Checking $LOGICAL_DEV -d megaraid,$N" smartctl -H -d megaraid,$N $LOGICAL_DEV > /dev/null 2>&1 if [ $? -eq 0 ]; then echo "Disk $N exists. Health status:" smartctl -H -d megaraid,$N $LOGICAL_DEV | grep "SMART overall-health" echo "---" else # No more disks found break fi done If you want, I can produce: for N

Hardware RAID controllers (such as Dell PERC, LSI MegaRAID, Avago) create virtual disk devices (e.g., /dev/sda , /dev/sdb , /dev/sdc ) that represent logical RAID volumes rather than individual physical disks. When you run smartctl -a /dev/sda without any extra parameters, the utility sees that the device is managed by a known RAID controller driver and returns the error message you see. When you run smartctl -a /dev/sda without any

Reviewing this output map reveals that while /dev/sda exists as a combined virtual target, the controller hosts underlying drives mapped internally as index coordinates 0 , 1 , and 2 . Method 2: Querying via StorCLI / PercCLI If you want
