Smartctl Open Device Dev Sda Failed Dell Or Megaraid Controller Please Try Adding 39d Megaraid N 39 Extra Quality |link| <2024>

For many systems with a single RAID volume, the command that works is:

✅ Works perfectly once you add -d megaraid,N . Common mistake: Forgetting to specify the physical disk index. Best practice: Use --scan to discover disks + indexes automatically.

If you need help corresponds to megaraid,N , I can explain how to use perccli to blink the drive light. For many systems with a single RAID volume,

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.

Find the appropriate storcli RPM or DEB from Broadcom. Run Inquiry: storcli /c0 show Find Drive ID: Look under the "PhysDrv" column. Method 3: Testing Other Device Types If you need help corresponds to megaraid,N ,

For example, to check the very first physical disk on the controller, try running: smartctl -a -d megaraid,0 /dev/sda Use code with caution.

This issue typically arises because smartctl attempts to scan /dev/sda as a standard, standalone SATA or NVMe drive. However, on a system equipped with a hardware or an LSI MegaRAID card, /dev/sda is actually a logical virtual disk managed by the controller firmware. The operating system cannot see the underlying physical drives directly, which blocks the standard S.M.A.R.T. commands. But smartctl tries to send S

: If the command still fails with minor errors, you can try adding the -T verypermissive flag to ignore mandatory SMART command failures that the controller might be blocking. Troubleshooting Summary

The storcli utility (formerly MegaCLI ) is the official command-line tool for managing LSI/Avago MegaRAID and Dell PERC controllers. It provides the most detailed and accurate device information.
