I have 7835H-2400 with CCM 3.3. It is equipped with two disks running RAID1. Now, I will be upgrading CCM to 4.3, which requires (Win2003) 72GB of disk space. I would like to purchase additional two disks for each of 7835s so I can have two disks (existing ones) configured as a single logical 72GB filesystem, and remaining two (new ones) configured as a mirror. It looks nice in theory, however, I haven't found anywhere any procedure or a guideline how to perfrm such task. When and how should I reconfigure RAID? Can I break existing RAID 1 and extend existing 36GB filesystem to 72GB? Will CCM3.3 accept that? Or should I re-create whole RAID structure during a bootup process just before installing Windows 2003? Is it possible to extend one logical filesystem through two 36GB disks, at all?
