 newfs_vxfs(1M)                                               newfs_vxfs(1M)

 NAME    [Toc]    [Back]
      newfs_vxfs: newfs - create a new VxFS file system

 SYNOPSIS    [Toc]    [Back]
      newfs [-F vxfs] [-B] [-O disk_type] [-R swap] [-V] [-v]
           [mkfs_vxfs_options] special

 DESCRIPTION    [Toc]    [Back]
      newfs -F vxfs builds a VxFS file system by invoking mkfs.  special
      specifies a character (or raw) file (for example, /dev/rdsk/c0t6d0).

    Options    [Toc]    [Back]
      newfs recognizes the following options:

           -B             Reserve space for boot programs past the end of
                          the file system.  If the file /usr/lib/uxbootlf is
                          present on the system, sufficient space to
                          accommodate that file is reserved; otherwise 691
                          kilobytes are reserved.  This option decreases the
                          size of the file system being created.  This
                          option cannot be used if the file-system size is
                          also specified using -s (see mkfs_vxfs options

           -F  vxfs       Specify the file-system type vxfs.

           -O disk_type   Use disk parameters from the disk_type named in
                          /etc/disktab.  This option is provided for
                          backward compatibility with previous HP-UX
                          releases. Any parameters specified on the command
                          line will the corresponding values in
                          /etc/disktab.  Any values not specified in the
                          command line and not shown in /etc/disktab are

           -R swap        Reserve swap megabytes of swap space past the end
                          of the file system.  This option decreases the
                          size of the file system to be created by the
                          specified number of megabytes.  -R cannot be used
                          if the file-system size is also specified using -s
                          (see mkfs_vxfs options below).

           -v             Specify verbose mode.  newfs prints out its
                          actions, including the parameters passed to mkfs.

           -V             Echo the completed command line, but do not
                          execute the command.  If not valid, -V prints an
                          error message.  The command line is generated by
                          incorporating the user-specified options and other
                          information derived from /etc/fstab.  This option
                          allows the user to verify the command line.

 newfs_vxfs(1M)                                               newfs_vxfs(1M)

      NOTE: You can specify the -R and -B options in the same command line.
      In that case, both the requested swap space and the space needed for
      boot programs are reserved.  These options are used when the file
      system size is defaulted to the size of the entire disk.

    mkfs_vxfs Options
      The following additional command-line options can be used to override
      default parameters passed to mkfs_vxfs:

           -b block_size  File system block size in bytes. The default value
                          is 1024 bytes for systems smaller than two
                          terabytes.  For Version 5 disk layout file systems
                          larger than two terabytes, the maximum file system
                          size is dependent on the block size.  A four
                          terabyte file system requires a 1K block size, An
                          eight terabyte file system requires a 2K block
                          size, a 16 TB file system requires a 4K block
                          size, and a 32 TB file system requires an 8K block

           -o  largefiles | nolargefiles
                          Valid only for the Version 4 and 5 disk layouts.
                          This option controls the largefiles flag for the
                          file system.  If largefiles is specified, the bit
                          is set and files two gigabytes or larger can be
                          created.  If nolargefiles is specified, the bit is
                          cleared and files created on the files system are
                          limited to less than two gigabytes.  The default
                          is nolargefiles.  See mkfs_vxfs(1M),

           -s size        File system size in DEV_BSIZE blocks (defined in
                          <sys/param.h>).  The default value is the size of
                          the entire disk or disk section, minus any swap or
                          boot space requested.  The size specifies the
                          number of sectors in the file system.  By default,
                          size is specified in units of DEV_BSIZE sectors.
                          However, you can append a suffix to size to
                          indicate another unit of measure.  Append k or K
                          to indicate that the value is in kilobytes, m or M
                          to indicate megabytes, or g or G to indicate

    Operands    [Toc]    [Back]
      newfs recognizes the following operand:

           special        A character (raw) file.

 EXAMPLES    [Toc]    [Back]
      To create a VxFS file system on /dev/rdsk/c1t5d0 and reserve 40
      megabytes of swap space.
