A utility for Linux, providing access to and control over SCSI disk and storage settings, including timeout values, queue depths, and more.

What is Sdparm?

sdparm is a command line utility for Linux that allows querying and modifying parameters on SCSI disks and storage devices. It provides a simple way to view and adjust settings like timeout values, queue depths, error recovery options, and more without having to directly edit configuration files.

Some key features of sdparm include:

• Get and set various device settings like timeouts, queue depths, write cache enable/disable, and more
• View device identification details like model, firmware version, and more
• Send commands like start/stop unit, spin up/down of disks
• Modify behavior during error recovery like lowering retry counts
• Read SMART information to check device health
• Simple text output for automation scripts to parse

sdparm is useful for systems administrators and IT professionals who need to tune settings on SCSI storage devices to optimize performance or change behavior. It can help resolve issues with problematic devices that are not responding well. As it does not require directly editing configuration files, sdparm simplifies the management and tuning of Linux SCSI subsystems.
