after partition using fdisk, i can not see the new device file (/dev/sdd1)

I used fdisk -l to partition /dev/sdd, use the entire disk as partition 1. it looks successful:
# fdisk -l /dev/sdd

Disk /dev/sdd: 10.7 GB, 10737418240 bytes
64 heads, 32 sectors/track, 10240 cylinders
Units = cylinders of 2048 * 512 = 1048576 bytes
Sector size (logical/physical): 512 bytes / 512 bytes
I/O size (minimum/optimal): 512 bytes / 512 bytes
Disk identifier: 0x35e3e2c4

Device Boot Start End Blocks Id System
/dev/sdd1 1 10240 10485744 83 Linux


the problem: i don't see the device file /dev/sdd1. tried to delete it and partition again, the same.

also tried
- mknod b 8 70 /dev/sdd1, to manually create it, but when i use oracleasm createdisk DISK2 /dev/sdd1, the command won't recognize manually crated /dev/sdd1.
- reboot the server,
- "partprobe" command, no luck.

in addition, cat /proc/partitions seems including /dev/sdd1:
cat /proc/partitions
major minor #blocks name
