It depends... You can replace the drives one at a time, then extend the array and logical disk using the HP ACU. Once the array is extended, you can then use DISKPART to extend the disk. No down time required. If you do this, you are taking the chance that you won't lose another drive while the array is rebuilding each time you replace drive, but I have done it and it is pretty painless. The other way is to blow away the array, put your new drives in, create a new array, create a new disk, format and recover your files from backup. This way you know you will have down time and schedule it. -Brian

This gives me a single 203 GB logical drive. I would like to increase storage on this server to as much as possible. I see that there are 300GB SCSI drives that are available for this server (about $1000 each). So my question is... what is the best way to do this? Remove the 4 74GB drives and replace them w/ 4 300GB drives in a new RAID 5 configuration? The current 1 logical drive is "D:" on Windows 2003 server, and only contains a single Firebird SQL database file. ~ Upgrade to Next Generation Antispam/Antivirus with Ninja! ~ ~ <http://www.sunbelt-software.com/SunbeltMessagingNinja.cfm> ~
