.Sh DESCRIPTION
|
||||
.Nm Ccdconfig
|
||||
is used to dynamically configure and unconfigure concatenated disk
|
||||
devices, or ccds. For more information about the ccd, see
|
||||
.Xr ccd 4 .
|
||||
.Pp
|
||||
The options are as follows:
|
||||
.Bl -tag -width indent
|
||||
.It Fl c
|
||||
Configure a ccd. This is the default behavior of
|
||||
.Nm ccdconfig .
|
||||
.It Fl C
|
||||
Configure all ccd devices listed in the ccd configuration file.
|
||||
.It Fl f Ar config_file
|
||||
When configuring or unconfiguring all devices, read the file
|
||||
.Pa config_file
|
||||
instead of the default
|
||||
.Pa /etc/ccd.conf .
|
||||
.It Fl g
|
||||
Dump the current ccd configuration in a format suitable for use as the
|
||||
ccd configuration file. If no arguments are specified, every configured
|
||||
ccd is dumped. Otherwise, the configuration of each listed ccd is dumped.
|
||||
.It Fl M Ar core
|
||||
Extract values associated with the name list from
|
||||
.Pa core
|
||||
instead of the default
|
||||
.Pa /dev/mem .
|
||||
.It Fl N Ar system
|
||||
Extract the name list from
|
||||
.Pa system
|
||||
instead of the default
|
||||
.Pa /netbsd .
|
||||
.It Fl u
|
||||
Unconfigure a ccd.
|
||||
.It Fl U
|
||||
Unconfigure all ccd devices listed the ccd configuration file.
|
||||
.It Fl v
|
||||
Causes
|
||||
.Nm ccdconfig
|
||||
to be verbose.
|
||||
.El
|
||||
.Pp
|
||||
A ccd is described on the command line and in the ccd configuration
|
||||
file by the name of the ccd, the interleave factor, the ccd configuration
|
||||
flags, and a list of one or more devices. The flags may be represented
|
||||
as a decimal number, a hexadecimal number, a comma-separated list
|
||||
of strings, or the word
|
||||
.Dq none .
|
||||
The flags are as follows:
|
||||
.Bd -unfilled -offset indent
|
||||
CCDF_SWAP 0x01 Interleave should be dmmax
|
||||
CCDF_UNIFORM 0x02 Use uniform interleave
|
||||
.Ed
|
||||
.Pp
|
||||
The format in the
|
||||
configuration file appears exactly as if it were entered on the command line.
|
||||
Note that on the command line and in the configuration file, the
|
||||
.Pa flags
|
||||
argument is optional.

||||

|
||||
.Ed
|
||||
.Pp
|
||||
.Sh EXAMPLE
|
||||
The following command, executed from the command line, would configure ccd0
|
||||
with 4 components (/dev/sd2e, /dev/sd3e, /dev/sd4e, /dev/sd5e), and an
|
||||
interleave factor of 32 blocks.
