Resizing a LEM Virtual Appliance v5.4 or above

The default size of the LEM virtual appliance is 250 GB. Starting with version 5.4, you can increase and decrease the capacity of your LEM virtual appliance using two distinct methods. The following sections describe how to do each.

Increasing the LEM Virtual Appliance

You can increase the capacity of your LEM virtual appliance by increasing the hard disk in your vSphere or Hyper-V client. If you want to increase the size of your virtual appliance, consider the following notes:

  • Due to licensing restrictions in versions before 5.6, you can only increase the disk size up to a maximum of 1 TB.
  • After you increase the size of your virtual disk, you cannot decrease it using the same methods.
  • You cannot increase the size of your virtual appliance if you have snapshots for the VM.

Decreasing the LEM Virtual Appliance

If you need to decrease the capacity of the virtual appliance, create a smaller (secondary) hard disk for the virtual appliance in your vSphere or Hyper-V client, and then start the virtual appliance to automatically clone the existing disk to the secondary hard disk.

Note: The new disk must be large enough to accommodate all of the data on the existing disk, but it does not have to have the same maximum capacity.

To clone a disk in vSphere:

  1. Open vSphere.
  2. In the left pane, select the LEM appliance.
  3. In the Inventory menu, click Virtual Machine > Power > Shut Down Guest.
  4. Add the new disk:
    1. In the Inventory menu, click Virtual Machine > Edit Settings.
    2. Click Add.
    3. In the center pane, select Hard Disk, and then click Next.
    4. Select Create a new virtual disk, and then click Next.
    5. Enter the settings for a new hard disk that is large enough to accommodate all of the data on the existing disk.
    6. Click Next.
    7. In the Virtual Device Node menu, select SCSI (0:2), and then click Next.
    8. Click Finish.
    9. Click OK.
  5. Back on the vSphere Client window, click Inventory > Virtual Machine > Power > Power On. The appliance starts up, clones the primary disk to the new disk, and then shuts down. This takes between 15 minutes and several hours, depending on the size of the disk.
  6. Replace the old disk with the new one:
    1. In the Inventory menu, click Virtual Machine > Edit Settings.
    2. In the left pane, select the old hard disk.
    3. Click Remove.
    4. Select the new hard disk.
    5. In the right pane, select SCSI (0:0) in the Virtual Device Node menu.
    6. Click OK.
  7. Power on the LEM appliance.

To clone a disk in Hyper-V:

  1. Open Hyper-V Manager.
  2. In the left pane, select the LEM appliance.
  3. In the Actions pane (right), click Shut Down.
  4. Add the new disk:
    1. In the Actions pane, click Settings.
    2. In the left pane under Hardware, click IDE Controller 0.
    3. In the right pane, select Hard Drive, and then click Add.
    4. Under Virtual hard disk (.vhd) file in the Media section, click New.
    5. On the New Virtual Hard Disk Wizard window, select Fixed size and then click Next.
    6. Specify a name and location for the new disk, and then click Next.
    7. Specify a size for the new blank disk that is large enough to accommodate all of the data on the existing disk, and then click Next.
    8. Click Finish.
    9. In the left pane under IDE Controller 0, select the new hard disk.
    10. In the right pane, select 1 in the Location menu.
    11. Click OK.
  5. Back on the Hyper-V Manager window, click Start in the Actions pane. The appliance starts up, clones the primary disk to the new disk, and then shuts down. This takes between 15 minutes and several hours, depending on the size of the disk.
  6. Replace the old disk with the new one:
    1. In the Actions pane, click Settings.
    2. In the left pane under IDE Controller 0, select the old hard disk.
    3. In the right pane, click Remove.
    4. In the left pane under IDE Controller 0, select the new hard disk.
    5. In the right pane, select 0 in the Location menu.
    6. Click OK.
  7. Power on the LEM appliance.
