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

You can try to list all drives behind the controller to identify the correct N value (starting from 0, 1, 2...): smartctl -a -d megaraid,0 /dev/sda Use code with caution.

For hardware RAID environments like Dell PowerEdge servers with PERC controllers or other LSI-based MegaRAID cards, smartctl requires a special -d megaraid,N syntax. The N value is a non-negative integer (usually 0 to 127) that identifies the specific physical disk to query.

The output will display the exact syntax needed to communicate with each device:
