Related terms
- Core dump
When the VMkernel of an ESX host fails, the host saves a diagnostic image of its state. Possible destinations are a dump partition (ESX-OSData unless changed), a VMFS datastore file, or a remote ESX Dump Collector reached over the network.
- Core dump target
The location an ESX host writes core dumps to, which can be a diagnostic partition, ESX Dump Collector or a file on VMFS (except VMFS on software iSCSI). A host with none configured has nowhere to save them.
