Prior to version 4 of ESXi you need to configure the scratchconfig. Is this still recommended or necessary?
I can't find anything in the documentation or in the knowledgebase.
According to this article :
"The ScratchConfig.ConfiguredSwapState and ScratchConfig.ConfiguredScratchLocation settings are required for HA in ESXi 3.5. They are not required for HA in ESXi 4.0..."
Hope it helps.
