Hello, Pankaj.

Probably you are not starting your RAID. You can check it with
cat /proc/mdstat. If not, well, you can mark the partitions forming the RAID
with persistent superblock (fd partition type in fdisk)) for starting
automatically the RAID on boot, or fill in the /etc/raidtab file with the
values of your current RAID and start it manually (see raidtools2 package).

Also you can read RAID-HOWTO for unvaluable information.
