My Client is looking to upgrade the Hard Drives in their HP Proliant ML310 G5 Server running SBS2003. Currently they have (3) 146GB SAS drives running RAID 5. They want to go to (4) 300GB SAS drives running RAID 5. Now I'm more familiar with Dell PE servers. Dell has the Dell Management Server software that will allow you to rebuild the RAID 5 Array after adding a new drive into the system. But I haven't found the equivalent in HP software to do this. Can someone point me to the right software on a HP Proliant ML310 G5 to accomplish this.
