CX-400 need to add new/additional disks to current LUN/RAID group

[woodc]

We have a CX-400 with one RAID group/LUN that we need to expand by adding more disks.

We physically installed the disks then went under the RAID group in Navisphere 6 and used the expand button to add 1 of the new disks. This took about half a day to "transition" and now the new disk is listed but the size has not changed (RAID 5 BTW). There is now more free space in the graphic shown under the partition tab of the RAID group, the free space went up under the general tab of the RAID group and under the general tab of the LUN the RAW capacity went up...but we do not know how to complete this to actually make the free space usable by the attached OS (Server 2000) Disk management still shows the disk as being the old size.

Any help would be greatly appreciated!

The first thing you will need to do is use the "Defrag RAID Group" utility when you right click on it and view properties. This will allow the free space of the new addition to be added to the stripe set.

Once this has been done you will need to use the "diskpar" utility located on the resource kit for 2000 to expand the partition. Keep in mind, you will only be able to do this if your disk is in basic mode.
