How to Place a UFS File System on a Diskette

Even though the procedure for adding a UFS file system is the same for UFS diskettes formatted on IA platforms and SPARC platforms, a UFS diskette formatted on a SPARC platform can only be used on another SPARC platform, and a UFS diskette formatted on an IA platform can only be used on an IA platform.

  1. Format the diskette for a UFS file system.

    Use "How to Format a UFS Diskette".

  2. Create a SunOS file system on the diskette. 


    $ /usr/sbin/newfs -v /vol/dev/aliases/floppy0

    -v

    Prints status messages. 

    /vol/dev/aliases/floppy0

    Indicates the location of the floppy.  

    The newfs(1M) command displays a message asking you to confirm the creation of the file system.

  3. Confirm the creation of the file system. 


    newfs: construct a new file system
       /vol/dev/aliases/floppy0:(y/n)? y

    A status message is displayed, indicating the particulars of the file system and the diskette's formatting.

    The diskette is now ready to be used on a SPARC platform. However, before Volume Management recognizes it, you must run the volrmmount command, as described in the following steps.

  4. Invoke the volrmmount command using the -i option to notify Volume Management that the diskette is inserted. 


    $ volrmmount -i floppy0

  5. Verify that the UFS file system is on the diskette by using the ls command on the /floppy directory.

    If the floppy0 subdirectory appears, the diskette has a UFS file system and has been mounted properly. 


    $ ls /floppy
floppy0
