I have a client with an HP ML350 G3 and they are running very low on disk space on their RAID5.  They have 3 slots open for disk drives and I want to add more drives to increase their disk space.  Once I add the drives do I have to use a partition tool to enlarge the partition or will the RAID configuration software allow me to do this?

I believe that the raid utility will allow you to enlarge the volume, but you'll still have to run something in whatever OS you are running to actually enlarge the partition.

Which raid card is in there... I think it came with an adaptec? What OS and tool do you use to manage the raid controller?

Depends on the RAID controller.
You should be able to definitely create a New RAID with a New drive letter with no problem, but if you want to expand, it is controller dependent.

I hope this helps !

An ML350 G3 is going to be 3 years or 4 years old so you're probably talking 36GB or smaller disks. There's no economic sense in buying any more 36 or 72GB disks when there are 300GB disks that can fit in the three spare slots unless you are going to gamble with second hand ones. Just shove a couple of 147's or 300's, move the data onto a new array and the customer's capacity problem is solved for 3 more years rather than 6 months.

If you have already bought the disks then expansion is pretty simple; upgrade to the latest Proliant Support Pack, (and upgrade to the latest firmware at the same time if you want to do the job well.) Then add the disks physically first and open the array configuration utility (ACU). You'll see the add disks to array option in the right hand pane when you select the array and after adding the disks the option to expand the array will appear when you select the logical disk.
I recently did this to my file server, which is a ML 350 G. Using the Smartstart RAID utility that came with the server, I saw no option of simply expanding the RAID without recreating the whole thing from scratch, which, of course, wipes out the data from the RAID. Because I inherited a system partition with 100mb of free space, I backed up all the data and active directory using Arcserve 11, verified the backup by conducting a test backup, and then shut down the server, installed the new drive, and booted off the SmartStart CD.

I wiped out the old raid and created a new raid with the new hard drive in the raid. I reinstalled Windows 2003 (specified a system partition of 20gb) reinstalled Arcserve, and restored from backup. The VP came in the next day and didn't even notice anything was amiss. I was quite happy, even though it was a lot of work.

You shouldn't have been using SmartStart Beachdude67, it's a piece of pie to expand as long as you do it all live. Rebooting to the install CD was the wrong thing to do.

Actually I take that back, since the rebuild takes so long it was probably best in your case to backup, shutdown, swap, restore. Depends where the OS is installed though.
Ha, but it worked.
