No option for Expand Array after adding disk.

[Jkarlow]

I have an issue trying to add disk space to my Array configured on a P410i raid controller. When I add the disk, the ACU see it, but when I right click the array/disk, I only have options to "Add Spare", or "New Array". Nothing for "Expanding the Array". I slapped the disk in a couple other HP Proliant DL G7 servers with same/simular setups, and I DO have the option to expand. Firmware is same, and all have Cache battery backups. But believe something is not set correctly in the controller configuration. I have tried comparing the configs line by line, but having issues determining what needs setup/enabled. Any advice would be greatly appreciated.
