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
