If a scratch partition is not set up, you might want to configure one, especially if low memory is a concern. When a scratch partition is not present, vm-support output is stored in a ramdisk.


The directory to use for the scratch partition must exist on the host.


  1. In the vSphere Client, select the host in the inventory.
  2. Click the Configuration tab.
  3. Under Software, click Advanced Settings.
  4. Select ScratchConfig.
    The field ScratchConfig.CurrentScratchLocation shows the current location of the scratch partition.
  5. In the field ScratchConfig.ConfiguredScratchLocation, enter a directory path that is unique for this host.
  6. Reboot the host for the changes to take effect.
