:camcontrol(8) is your friend here

    Depends on the driver.  For AHCI, if the AHCI chipset has the
    appropriate support it should detect the insertion automatically.
    If it doesn't then the port might not support hot-swap detection
    and camcontrol won't have any effect.

    That might make a nice mini project, though... to have the AHCI driver
    handle the SCSI bus-reset command from camcontrol and force the port
    into a hard reset sequence.

    For NATA/IDE attachments (adXX) you might be able to use natacontrol
    to force it to rescan the bus.

    For other devices it depends on the driver.
