If a scratch partition is not set up, you might want to configure one, especially if the host is low on memory. When a scratch partition is not present, system logs are stored in a ramdisk.


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


  1. From the vSphere Client, connect to the vCenter Server.
  2. Select the host in the inventory.
  3. Click the Configure tab.
  4. Select System.
  5. Select Advanced System Settings.
    The setting ScratchConfig.CurrentScratchLocation shows the current location of the scratch partition.
  6. In the ScratchConfig.ConfiguredScratchLocation text box, enter a directory path that is unique for this host.
    For example, /vmfs/volumes/DatastoreUUID/DatastoreFolder.
  7. Reboot the host for the changes to take effect.
