Hai all
I have 3 scsi harddisk of capacity 18 gb each.
I configured raid using diskdruid at during the installation time of RedHat 7.0.
I configured RaID as follows

/boot -sda1 not raid
/ /dev/md0 Raid 1
/var /dev/md1 Raid 5
/home /dev/md2 Raid 5
/usr /dev/md3 Raid1
/opt /dev/md4 Raid1

Raid1 is setup in two different disks & Raid 5 is setupped in 3 different disks.

When i tested the raid by removing a hard disk and booting with boot disk the system halted at prompt
asking the root password for repairing disks.I tested by removing the disk one by one The result is the same at all times.
I read from the documentation that the raid will automatically take the data from other disks even a disk is failed. But this is not happening in my case.
What is wrong with me.Please help
