Expanding Raid5 on DL380 G6

Expanding Raid5 on DL380 G6

I have a Raid5 already in place across 4 136.76GB Drives, and i want to add 4 identical drives to the existing raid and expand the partition.


Running Windows Server 2008,

Smart Array P410i controller, accelerator enabled.


i attached screenshots from the system management.


Questions are,

Can i do it (add 4 drives) without rebuilding the array and subsequently destroying the data (i want to SAVE the data)

How do i do it? (via startup RAID configuration (if there is something), or will it appear as an option on the system management homepage)

To be able to expand the arrays you have't got the right bits on your P400 ( I had a similar problem). I added a 512MB BBWC module to the controller and then the expansion option became available.


If you go to this link


and see the section


Does the Smart Array P410 have battery-backed cache and what features require BBWC?
