Extend Raid5 with a new HD (HP DL380 G3)

  • 772

Because one of our customers is running out of disk space, I need to extend his Raid5 with one more disk.

At the moment the raid5 contains 3x72gb harddisk. The harddisk i want to add is exactly the same one.

He's running Win2003std on a HP Pro Liant DL380 G3

what would be the best (fastest) way? and do i need to convert the partition to dynamic volume?

anybody tried that with the HP tools?

kind regards

    Assuming you're using the HP controllers: You'll need to reboot, hit whatever the key is to get into the RAID controller, add the new drive to the container, and then wait for the array to rebuild. When you boot up, you'll need to expand the partition.

    It's fairly simple once you start doing it, but schedule more downtime than you need and take a backup first just to be safe. That's just good practice any time you're messing with the storage layer.

    If you're using software raid or a non-HP controller... well, you're kinda on your own, kid.

  2. If you installed the HP Array Configuration Utility CLI, you should have a hpacucli.exe program which allow you to add your disk without rebooting your server.

    Not sure how it works on windows but it does without problems on linux.

    It should be something like

    hpacucli ctrl slot=0 array A add drives=1I:1:4

    then extend the logical drive

    hpacucli ctrl slot=0 logicaldrive 1 modify size=max

  3. On basic disk extend hardware RAID by partition software, of course, It's way to convert your disk to dynamic disk, then using Spanned Volume to enlarge the capacity. An article http://www.extend-partition.com/resize-windows-server-2008-partition.html for resizing server partition.
