ESX Commands - esxcfg-dumppart
Finally have a second to log into the test ESX and mess with esxcfg- commands again.
Today, _esxcfg-dumppart, _this command can be used to list, create and activate dump partitions used by the VMKernel during a crash. I would bet almost everyone automatically creates one of these during the install of ESX. What I mean is I never even tried to not create a dump part on installation. I was trying to think of a practical use for this. Maybe we want the dump to go to a SAN partition or a some other drive? I would guess this would make is possible.
I found a neat PDF from VMware while researching this command.
