smartctl -a -d megaraid,1 /dev/sda

If you can't install MegaCLI or perccli , you can brute-force find the ID by running a simple loop. A community approach suggests iterating smartctl from 0 to around 30 to find all disks in smartctl , as smartctl -d ,0 /dev/sda is the same as smartctl -d ,0 /dev/sde if you keep using N .

Hardware RAID controllers (like Dell PERC H330, H730, H740, or LSI MegaRAID 9260, 9361) create (logical drives). To the operating system, these volumes look like single block devices— /dev/sda , /dev/sdb , etc. But smartctl tries to send S.M.A.R.T. commands directly to that device file. The RAID controller intercepts those commands and does not pass them to individual physical drives unless explicitly instructed.

By pairing smartctl with the appropriate -d megaraid arguments, you can effectively monitor the individual health, temperature, and bad sector counts of your underlying physical disks without tearing down your hardware RAID arrays. To help tailor these steps, could you tell me: Hardware RAID controllers (like Dell PERC H330, H730,

First, ensure you have smartmontools installed and find the correct device node (usually /dev/sda or /dev/sgX ). You can use lsblk to list devices. 2. Probe the Drive Structure commands directly to that device file
