I am struggling to install debian squeeze (64 bit) OS in the system which is having RAID 1. While partitioning the drive, It says an error Operation not permitted during write on /dev/md126 . I am using IBM System x3250 M4 server model.
For more info about the server:

Here, You can find the screenshot of the disk partitioning error.
Whether squeeze is detecting the RAID ( controller ) or not ?
How to solve this error?
