Hello there,

We had a RAID0 setup on PE2900 with PERC5/i card, 3 HDs under the 
first Virtual disk array. Recently, we purchased addtional 5 HDs to create 
the second virtual disk array. I am able to use Dell OMSA utility to 
create a new virtual disk and do fast initialization afterwards.

My question is to partition the new raid0 and format the disks in order to 
mount it. The new virtual disk is slightly above 1TB, (250Gx5HDs), and we 
are using Debian/Ubunntu OS. I would much appreicate if anyone could help 
me on this issue. I search around for a while but unfortunately find no 
solution. I am really new to the Linux and server world.

Please also find the part of dmesg output in the following. Thanks for 
your help in advance!

PS. the old raid 0 is under /dev/sdd, including the 3 HDs under /dev/sda,
/dev/sdb, /dev/sdc, respectively. And we have 3 external HDs for backup.
