I have a DELL poweredge 2400 (PERC 2Si controller) with a RAID 1 (SYSTEM) and RAID 5(data) partition. I want to expand by another disk into the RAID 5 partition. How do I do that?

    check the documentation of the controllers. Older cards dont allow dynamic resizing.

    dynamic resizing isn't awfully common either tbh, i would expect you having to lose all the information on your RAID before you can do anything like resizing etc.

    Accepted Solution

    Yes, you can add a disc to your RAID 5 set. You'll need to make sure that your PERC 2/Si is at the current driver/firmware revision:

    And Array Manager should also be at the current revision.

    You can then right-click on your RAID 5 set in Array Manager and select Expand.

    Once the array has completed the expansion, you'll need to open a command prompt and run diskpart.exe (from the W2K Resource kit, W2K3 ships with it) to expand the Windows partition.

    If you're running Linux, the procedure is slightly different,
