I've noticed that one of the drives has "unassigned" status. Does it mean that it's a spare disk?

How I can safely add it to this existing array?
Hi, I've successfully added the fourth drive to the array. I'm trying to extend the logical drive now:
hpacucli ctrl slot=0 ld 1 modify size=max
and I received the following warring:
Warning: Extension may not be supported on certain operating systems. Performing extension on these operating systems can cause data to become inaccessible. See ACU documentation for details. Continue?
I'm running CentOS 6.3 - where I can check if CentOS supports this?
If it does and I will extend the logical drive on the RAID card do I still have to create a new partition, resize physical volume and extend the logical volume on the OS itself to be able to use this extra space?
