Specifying Tape Characteristics

If you do not specify any tape characteristics, the ufsdump command uses a set of defaults. Table 36-1 shows some arguments to the ufsdump command that work well for different types of tape cartridges. You can specify tape cartridge (-c), density (-d), size (-s), and number of tracks (-t). Note that you can specify the options in any order as long as the arguments that follow match the order of the options.
