Reconfigure diagnostic partition using Get-EsxCli -V2

The following powershell snippet is going to unconfigure the diagnostic coredump partition using the esxcli version 2 cmdlet. The second part will reconfigure the diagnostic partition with the ‘smart’ option so that an accessible partition is chosen.

If you want to configure a new diagnostic partition the you will find the necessary information in the following VMware knowledge base article: Configuring a diagnostic coredump partition on an ESXi 5.x/6.x host (2004299). There will be additional steps to supply the partition id.

First we connect to the esxi host directly and insert the connection details in the variable $srv:

Then we create a esxcli object $esxcli using the variable $srv we created previously:

Now we create a variable $arg to store the arguments we will provide later:

Setting the $arg property ‘unconfigure’ to true will deactivate the diagnostic partition:

The invoke command will invoke the command remotely on the esxi host. After execution the diagnostic partition is deactivated:

The second part starts with creating a new set of arguments:

Reactivate the coredump, because we deactivated it before:

Enable the coredump partition:

The ‘smart’ property will try to use an accessible partition:

The last argument will configure the diagnostic partition using the supplied parameters:

Reconfigure diagnostic partition

Reconfigure diagnostic partition with PowerCLI using Get-EsxCli
