Smartctl Open Device Dev Sda Failed Dell Or Megaraid Controller Please Try Adding 39d Megaraid N 39 Extra Quality !!link!! -

Here’s a concise review of the problem and solution:

Virtual arrays do not natively support physical Self-Monitoring, Analysis, and Reporting Technology (SMART) pass-through structures. Passing a raw geometry command down a generalized block route breaks at the controller level, generating the diagnostic message prompting for specific device arguments.

Your system will generate an output list mapping structural system endpoints:

sudo smartctl -t long -d megaraid,N /dev/sda Here’s a concise review of the problem and

Once you successfully retrieve S.M.A.R.T. data, it is crucial to understand what the numbers mean. Simply seeing a PASSED status at the top of the output is not sufficient—a disk can pass the overall health check while still having underlying problems.

/dev/sda -d megaraid,0 # /dev/sda, Physical Disk 0 /dev/sda -d megaraid,1 # /dev/sda, Physical Disk 1 /dev/sda -d megaraid,2 # /dev/sda, Physical Disk 2

: The /dev/sdX device passed to smartctl does not need to be the exact physical disk you are targeting—it is merely a handle to access the RAID controller. The -d megaraid,N parameter tells the controller which physical disk to query. data, it is crucial to understand what the numbers mean

When you try to run smartctl on a device (e.g., /dev/sda) connected to a MegaRAID controller, you might encounter the following error:

sudo smartctl -a -d megaraid,N /dev/sdX

In this output, the physical drives appear with Type: Direct-Access and Vendor: ATA . While this method does not explicitly give you the DID , it helps you verify that the drives are being detected and often shows you the controller‑specific ID under the Id: field. The -d megaraid,N parameter tells the controller which

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.

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