Smartctl Open Device Dev Sda Failed Dell Or Megaraid Controller Please Try Adding 39d Megaraid N 39 Extra Quality ((hot))

When using on a Dell server equipped with a MegaRAID (PERC) controller, you may encounter the following error:

This public link is valid for 7 days and shares a thread, including any personal information you added. This link or copies made by others cannot be deleted. If you share with third parties, their policies apply. Can’t copy the link right now. Try again later.

If you have perccli (Dell) or storcli installed, run: /opt/MegaRAID/perccli/perccli64 /c0 /eall /sall show Use code with caution. Copied to clipboard Look for the DID (Device ID) or Slot Number column. 2. Run the Correct Command Your system will generate an output list mapping

If you are working with SSDs behind a PERC controller, a more precise command that often works better for SATA-to-SAS translation is: smartctl -a -d sat+megaraid,N /dev/sda Use code with caution.

StorCLI (or the older MegaCLI) is the powerful official utility for managing Broadcom/LSI MegaRAID controllers.

Use this syntax:

This error occurs because and MegaRAID controllers hide physical drives behind a "Virtual Drive" abstraction . When you run smartctl /dev/sda , the tool tries to talk to the RAID volume itself, which doesn't support standard S.M.A.R.T. commands. Can’t copy the link right now

By ignoring the garbled "39" text and identifying the correct disk index, you will successfully bypass the "Device Open Failed" error and retrieve your SMART data.

You can view event logs for error detection with a command like MegaCLI -AdpEventLog -GetEvents -f events.log -a0 .

: If the drive is SATA rather than SAS, you may need a combined flag: sudo smartctl -a -d sat+megaraid,N /dev/sda Summary of Flags -a : Displays all SMART information.

In this case N=0 (device ID 0) and /dev/sda is the logical RAID volume. This should retrieve S.M.A.R.T. information for the first physical disk in the array. However, N=0 is not always the correct identifier; the actual device IDs can vary, as demonstrated in the following sections.

To resolve this issue, you need to inform smartctl about the presence of the MegaRAID controller and the logical drive number (N) associated with the disk drive you want to monitor. You can do this by adding the -d megaraid,N option to the smartctl command.

megacli -PDList -a0 | grep "Slot Number" # (if MegaCLI installed)

, replacing N with the correct index. If you are still struggling to get the correct data,

Before querying the drives, you must find out how the controller identifies each physical drive. smartctl includes a native scanning utility that detects hidden arrays. Run the following command with root or sudo privileges: sudo smartctl --scan Use code with caution.
