am sorry but i can't explain this problem in arabic

my problem is that after install Ubuntu server 10.04 on IBM blade server which is connected to a IBM DS4700 SAN Storage " the SAN is configured to use RAID10";
i have a multi access path to some partitions on the SAN therefore when i go to disk utility on the Ubuntu server i can see its doubling the SAN hard drives, each hard is showing two, i searched the IBM Site and i found out that i must install a utility to bundle the partitions, but Unfortunately they don't support Ubuntu,
i searched the Ubuntu website and i found that i need to install the multipath tool

apt-get install multipath-tools

i install it.

but i dont know what to do next can you help me please?

thanks
