If we take a look at sys/types.h,
/*
* minor() gives a cookie instead of an index since we don't want to
* change the meanings of bits 0-15 or waste time and space shifting
* bits 16-31 for devices that don't use them.
*/
#define major(x) ((int)(((u_int)(x) >> 8)&0xff)) /* major number
*/
#define minor(x) ((int)((x)&0xffff00ff)) /* minor number
*/
#define makedev(x,y) ((dev_t)(((x) << 8) | (y))) /* create dev_t
*/
So, 0x20449 is major # 0x04, a SCSI device, and minor # 0x00020049.
Just do an ls -l /dev/da* and you'll find your device: da2.
