NAME

SYNOPSIS
       disk_type] swap]

DESCRIPTION
       builds a VxFS file system by invoking

       special specifies a character (or raw) file (for example, or

   Options
       recognizes the following options:

	      Reserve space for boot programs past the end of the
			     file  system.  If the file is present on the sys‐
			     tem, 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  (see
			     options below).

	      Specify the file-system type

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

	      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.  cannot be used if the file-
			     system size is also specified using (see  options
			     below).

	      Specify verbose mode.
			     prints  out its actions, including the parameters
			     passed to

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

       NOTE: You can specify the and 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

	      File system block size in bytes. The default value is
			     1024 bytes for  systems  smaller  than  two  ter‐
			     abytes.   For  Version 5 disk layout file systems
			     larger than two terabytes, the maximum file  sys‐
			     tem  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 size.

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

	      File system size in
			     blocks (defined in 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  sectors.
			     However, you can append a suffix to size to indi‐
			     cate another unit of measure.  Append or to indi‐
			     cate  that the value is in kilobytes, or to indi‐
			     cate megabytes, or or to indicate gigabytes.

   Operands
       recognizes the following operand:

	      special	     A character (raw) file.

EXAMPLES
       To create a VxFS file system on or and reserve  40  megabytes  of  swap
       space.

FILES
       Disk description file.
       Static information about the file systems.
