Thank you very much for your answer.

I am going to do the expansion bynight, but I am going to expand the RAID
but no the logical drives because I have read in the HP Array Configuration
User Guide that it is not recommended doing this when you use Windows 2003
and MSCS. The reason is that in the Logical Drive Capacity Expansion process
the drives have to be configured as dynamic and MSCS required the disks as
basic. I wopuld create new logical drives.

Thank you again.
