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 Ns . .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 Use .Ar system as the kernel instead of the running kernel (as determined from .Xr getbootfile 3 ). .It Fl u Unconfigure a ccd. .It Fl U Unconfigure all ccd devices listed the ccd configuration file. .It Fl v Cause .Nm 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 CCDF_MIRROR 0x04 Support mirroring CCDF_PARITY 0x08 Support parity (not implemented yet) .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. .Bd -unfilled -offset indent # # /etc/ccd.conf # Configuration file for concatenated disk devices # .Pp # ccd ileave flags component devices ccd0 16 none /dev/da2e /dev/da3e .Ed .Pp .Sh EXAMPLE The following command, executed from the command line, would configure ccd0 with 4 components (/dev/da2e, /dev/da3e, /dev/da4e, /dev/da5e), and an interleave factor of 32 blocks. .Bd -unfilled -offset indent # ccdconfig ccd0 32 0 /dev/da2e /dev/da3e /dev/da4e /dev/da5e .Ed .Pp .Sh FILES .Bl -tag -width /etc/ccd.conf -compact .It Pa /etc/ccd.conf default ccd configuration file .El .Sh SEE ALSO .Xr ccd 4 , .Xr rc 8 .Sh HISTORY The .Nm command first appeared in .Nx 1.0a .
