If your Auto Deploy host has a built-in USB flash drive, and an error results in a coredump, the coredump is lost. Set up your system to use ESXi Dump Collector to store coredumps on a networked host.

Problem

If your Auto Deploy host has a built-in USB Flash, and if it encounters an error that results in a coredump, the coredump is not sent to the local disk.

Solution
1

Install ESXi Dump Collector on a system of your choice.

ESXi Dump Collector is included with the vCenter Server installer.

2

Use ESXCLI to configure the host to use ESXi Dump Collector. 

esxcli conn_options system coredump network set IP-addr,port
esxcli system coredump network set -e true
3

Use ESXCLI to disable local coredump partitions.

esxcli conn_options system coredump partition set -e false
