What version of RedHat enterprise? What kind of RAID card? What kind of hard drives??
You need to provide useful information, if you'd like a useful answer. Right now, the best thing you could do, is to contact IBM for hardware questions, and RedHat for Linux questions..you're paying them for support when RedHat Enterprise....

REEL 4 , adaptec raid card , the hard drive is come with IBM server , it should be IBM brand , can advise is there any command that I can check it ? thx
First clue should be that the two drives are active but you can only actually see one within RHEL, this would be a common effect of many types of raid cards. The second is to check the raid controller itself during boot and it will tell you if it actually has an array or not. If their is no array displayed, instead just both hard drives, then it's not actually running any form of raid.

1. yes , i see it with one drive , but I am sure if it is software raid or only one drive is active .
2. I can't boot it as this is production server .
What is the device called, if it's called sda then it won't be software raid, mdadm is the main tool for software raid in RHEL and would have labels like md0, md1, etc.
