I have a HP DL120 server running under co-location with a 2 disk RAID 1. Now i want to gain DB read speed by adding two more disks. My question is if the two disks automaticly will be included in the raid 1 or if the machine will have to be reconfigured in bois to include the two exta disks. The first confugoration to get the two disks in raid were bios config but now i can see and admin them from HP Array Configuration Utility.
(Using Smart Array B110i SATA RAID)

You machine will take up to 4 disks and will support a 4 disk RAID 10 array but you'll need to buy the 'HP Smart Array Advanced Pack' (HP P/N: 516471-B21) and one of the forms of flash-backed cache (ie. HP P/N's 534916-B21) if you don't already have one.
Once these are in place and you've got 4 MATCHING drives then you'll be able to boot into the HP ORCA utility via F9 or boot from a SmartStart CD/ISO (a better idea) and initiate a RAID-level migration from 1 to 10. Once complete this will either allow you to add the new space to any existing virtual disks or create new one/s.
As all before have said, make sure you've got good backups first ok :)
