The media argument causes the device media to be scanned. This
involves writing a data pattern to the media and then reading and
verifying the data written. You must include test parameters that
specify the media area to be scanned.
The following examples use the scan media command with different
test-parameters :
scu> media
scu: No defaults, please specify test parameters for transfer
