When VMware ESXi PSODs (Purple Screen), we require core dump from the failing system to analyze the failure. During a purple diagnostic screen, VMware ESX/ESXi attempts to write a VMkernel coredump to a previously-configured VMKCore (partition type 0xFC) partition on disk and/or to the ESXi Dump Collector service via the network.
This paper talks about utilizing an iDRAC vFlash USB partition for configuring it as a core dump collector. The intended audiences for this whitepaper are those who make use of VMware ESXi core dump partition to collect coredump for analyzing different failures. This paper is basically for people who plan to use a different storage (other than ESXi booted device or underlying storage) for creating core dump partition. It details about the steps to configure an iDRAC vFlash as a VMware ESXi core dump collector.
