Expand an array with 3Ware

Before expanding your array, please consider the size of array that you are moving to. Changing the size of the array could cause issues if a new cluster size must be assigned:

It is possible to expand an array with 3Ware using the 3DM2 web utility. Please follow the steps below to successfully expand the array using the Migration method:

  1. Install the new disks into the system. Keep in mind that is is an additive process, and not one where existing disks are removed. Also of note is that the disks need to be the same capacity as the original disks, else the total capacity of the new disk will only read as much of that of the existing disks. i.e new 6TB drives will only show up with 4TB available if an array with 4TB drives already exists.
  2. Once installed, open the 3DM2 page by opening a browser and navigating to https://localhost:888/
  3. Login with Administrator/admin256. For older units, or units that have just been re-imaged, the password may be 3ware.
  4. Once logged in, navigate to Management > Maintenance.
  5. Select the unit in the Unit Maintenance table (usually u0). 
  6. Select Migrate Unit and the bottom of the table. 
  7. Select the drives desired to expand the unit with by checking the Port ID next to them.
  8. It is suggested to leave the RAID level the same as the original configuration. As a rule, systems shipped with 8 drives and fewer would be RAID 5 while systems shipped with 9 drives and more would be RAID 6. 
  9. It is also suggested to leave the stripe size as the original as well. As a rule, systems with RAID configuration all shipped with a 256k stripe size.
  10. Select OK.

Once the unit has finished migrating (you can check the progress in the exacqVision client), the OS needs to be informed that the drive has expanded:

  1. Reboot the system once migration has completed.
  2. Log back into the system as the admin.
  3. Stop the exacqVision server service by (Windows) selecting Windows Key+R > type net stop exacqVisionServer > OK or (Linux) select Ctrl+Alt+T > type sudo /etc/init.d/edvrserver stop > press Enter > use admin256 for password.
  4. In Windows, select Start > right-click Computer > Manage > Disk Management > right-click existing array’s partition (i.e. D:) > Extend > cycle through the menu by selecting Next and then OK at the end. 
  5. In Linux, new partitions must be under 16TB. In this case, please call Support for assistance in expanding the array in the OS.
  6. Start the exacqVision server service by (Windows) selecting Windows Key+R > type net start exacqVisionServer > OK or (Linux) select Ctrl+Alt+T > type sudo /etc/init.d/edvrserver start > press Enter > use admin256 for password.
  7. Open the exacqVision Client and navigate to Config (gears) > Storage under the system being edited. Make sure the new capacity is the same as what was reported by the OS.

How to Expand an Array with an LSI Controller

Purpose: To show the process of adding a drive labeled Unconfigured Good to an existing array. This guide assumes that a new drive(s) has been added to at least one unused drive bay that will be used to expand.


Modify the Drive Group

  1. If the server was shut down, close the exacqVision client and log out of user and into admin.
  2. Minimize the exacqVision Client and open the LSI MegaRAID Storage manager. This can be accessed by either selecting Start > All Programs > MegaRAID Storage Manager > StartupUI or double-clicking the MegaRAID Manager icon on the Desktop (if present).
  3. The Host View page will open. Select the Host that comes up in the list to get the login window.
  4. Log in with the OS credentials configured for the system and select Login.
    (If using a legacy Exacq system, the credentials will be admin/admin256 in Windows and root/exacqvisionip in Linux.)
  5. Navigate to the Logical tab next to the Physical tab.
  6. Locate the proper Drive Group for RAID 5 or 6 then right-click it and select Modify Drive Group.
    (Select Drive Group: 0, RAID (5,6) for systems with only one Drive Group. For systems with the additional OS-on-RAID option, select Drive Group: 1, Raid (5,6))
  7. Select the box next to Confirm and then select Yes.
  8. Use the drop-down at the bottom of the page and select RAID 6 and then select Next.
  9. Select the box next to the Available Drive you want to add and then select Next.
  10. Confirm the Post modification settings are larger than the Current settings and select Finish.
  11. Reconstruction of the array will begin. This can take a large amount of time.
