If successful, you will bypass the initial controller failure blocks and pull standard diagnostic metrics, including device temperature, power-on hours, reallocated sector counts, and drive health status. Making the Configuration Permanent

A PASSED health status is only a snapshot from the disk’s firmware. The dangerous attributes listed above must be monitored over time to detect genuine failure trends. The smartctl open device failed error is a
The smartctl open device failed error is a standard and expected response when querying a hardware RAID controller. It is not an error with the drives, but a notification that you are not using the proper syntax to access the physical devices behind the controller. including device temperature
Step 2: Extracting Missing Physical IDs via MegaCli / StorCli
The hardware controller can pass S.M.A.R.T. commands directly to underlying disks using pass-through parameters. smartctl requires you to provide explicit instructions identifying the hardware architecture type ( megaraid ) and the precise hardware slot designation ( N ) where the physical drive resides. Step 1: Discover Physical Drive IDs ( N )
