68.Sh DESCRIPTION
69.Nm Ccdconfig
70is used to dynamically configure and unconfigure concatenated disk
71devices, or ccds.  For more information about the ccd, see
72.Xr ccd 4 .
73.Pp
74The options are as follows:
75.Bl -tag -width indent
76.It Fl c
77Configure a ccd.  This is the default behavior of
78.Nm ccdconfig .
79.It Fl C
80Configure all ccd devices listed in the ccd configuration file.
81.It Fl f Ar config_file
82When configuring or unconfiguring all devices, read the file
83.Pa config_file
84instead of the default
85.Pa /etc/ccd.conf .
86.It Fl g
87Dump the current ccd configuration in a format suitable for use as the
88ccd configuration file.  If no arguments are specified, every configured
89ccd is dumped.  Otherwise, the configuration of each listed ccd is dumped.
90.It Fl M Ar core
91Extract values associated with the name list from
92.Pa core
93instead of the default
94.Pa /dev/mem .
95.It Fl N Ar system
96Extract the name list from
97.Pa system
98instead of the default
99.Pa /netbsd .
100.It Fl u
101Unconfigure a ccd.
102.It Fl U
103Unconfigure all ccd devices listed the ccd configuration file.
104.It Fl v
105Causes
106.Nm ccdconfig
107to be verbose.
108.El
109.Pp
110A ccd is described on the command line and in the ccd configuration
111file by the name of the ccd, the interleave factor, the ccd configuration
112flags, and a list of one or more devices.  The flags may be represented
113as a decimal number, a hexadecimal number, a comma-separated list
114of strings, or the word
115.Dq none .
116The flags are as follows:
117.Bd -unfilled -offset indent
118CCDF_SWAP		0x01		Interleave should be dmmax
119CCDF_UNIFORM	0x02		Use uniform interleave
120.Ed
121.Pp
122The format in the
123configuration file appears exactly as if it were entered on the command line.
124Note that on the command line and in the configuration file, the
125.Pa flags
126argument is optional.

137.Sh EXAMPLE
138The following command, executed from the command line, would configure ccd0
139with 4 components (/dev/sd2e, /dev/sd3e, /dev/sd4e, /dev/sd5e), and an
140interleave factor of 32 blocks.
141.Bd -unfilled -offset indent
