Smartctl Open Device Dev Sda Failed Dell Or Megaraid Controller Please Try Adding 39d Megaraid N 39 Extra Quality Jun 2026

is a common error encountered by system administrators managing Dell PowerEdge servers or any enterprise hardware utilizing Broadcom / LSI MegaRAID controllers.

The output will expose how the software perceives the hardware matrix. You will typically see lines structured like this:

One will fail (non-existent drive) or return info for the correct disk. is a common error encountered by system administrators

To use the "-d megaraid,N" option, you'll need to determine the logical drive number or physical drive number on the MegaRAID controller. You can do this by:

smartctl -a -d megaraid,0 /dev/sda

/dev/sda -d megaraid,0 -a -m admin@yourdomain.com /dev/sda -d megaraid,1 -a -m admin@yourdomain.com /dev/sda -d megaraid,2 -a -m admin@yourdomain.com Use code with caution. Restart the daemon to apply changes: systemelf restart smartd Use code with caution. Troubleshooting Common Errors

The underlying rejects the direct request, causing smartctl to drop out and print its helpful hint: utilize the -d megaraid,N flag. To use the "-d megaraid,N" option, you'll need

You cannot just guess the number N . You need to know the physical drive ID recognized by the MegaRAID controller.

Once you have the ID (e.g., 0 , 1 , or 32 ), use the -d (device type) flag: smartctl -a -d megaraid,0 /dev/sda For SATA Drives: smartctl -a -d sat+megaraid,0 /dev/sda and potential issues

The operating system cannot fetch direct hardware telemetry from a virtual drive abstraction. Instead, the controller intercepts the command and triggers the error.

smartctl (Self-Monitoring, Analysis, and Reporting Technology) is a utility used to monitor and control hard drives and solid-state drives (SSDs) that support the SMART (Self-Monitoring, Analysis, and Reporting Technology) standard. It provides valuable information about a disk's health, performance, and potential issues, allowing users to take proactive measures to prevent data loss and system crashes.
