DESCRIPTION
builds a VxFS file system by invoking

Options
recognizes the following options:
Reserve space for boot programs past the end of the
file system. If the file 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 (see options below).

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.

Echo the completed command line, but do not execute the command.
If not valid, prints an error message. The command 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 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 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 giga-
bytes or larger can be created. If is specified, the bit is cleared and files created on the files system are lim-
ited 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 indicate another unit of measure. Append or to indicate that
the value is in kilobytes, or to indicate 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.
