Reconfigure diagnostic partition using Get-EsxCli -V2

by Harold Preyers | Nov 2, 2018 | ESXi, PowerCLI, VMware

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.

$srv = Get-VMHost ESXiHost
$esxcli = Get-EsxCli -VMHost $srv -V2
$arg = $esxcli.system.coredump.partition.set.CreateArgs()
$arg.unconfigure = "true"
$esxcli.system.coredump.partition.set.Invoke($arg)
$arg = $esxcli.system.coredump.partition.set.CreateArgs()
$arg.unconfigure = "false"
$arg.enable = "true"
$arg.smart = "true"
$esxcli.system.coredump.partition.set.Invoke($arg)

$srv = Get-VMHost ESXiHost

$esxcli = Get-EsxCli -VMHost $srv -V2

$arg = $esxcli.system.coredump.partition.set.CreateArgs()

$arg.unconfigure = "true"

$esxcli.system.coredump.partition.set.Invoke($arg)

$arg = $esxcli.system.coredump.partition.set.CreateArgs()

$arg.unconfigure = "false"

$arg.enable = "true"

$arg.smart = "true"

$esxcli.system.coredump.partition.set.Invoke($arg)

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

$srv = Get-VMHost ESXiHost
$esxcli = Get-EsxCli -VMHost $srv -V2
$arg = $esxcli.system.coredump.partition.set.CreateArgs()
$arg.unconfigure = "true"
$esxcli.system.coredump.partition.set.Invoke($arg)
$arg = $esxcli.system.coredump.partition.set.CreateArgs()
$arg.unconfigure = "false"
$arg.enable = "true"
$arg.smart = "true"
$esxcli.system.coredump.partition.set.Invoke($arg)

1	$srv = Get-VMHost ESXiHost

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

$srv = Get-VMHost ESXiHost
$esxcli = Get-EsxCli -VMHost $srv -V2
$arg = $esxcli.system.coredump.partition.set.CreateArgs()
$arg.unconfigure = "true"
$esxcli.system.coredump.partition.set.Invoke($arg)
$arg = $esxcli.system.coredump.partition.set.CreateArgs()
$arg.unconfigure = "false"
$arg.enable = "true"
$arg.smart = "true"
$esxcli.system.coredump.partition.set.Invoke($arg)

2	$esxcli = Get-EsxCli -VMHost $srv -V2

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

$srv = Get-VMHost ESXiHost
$esxcli = Get-EsxCli -VMHost $srv -V2
$arg = $esxcli.system.coredump.partition.set.CreateArgs()
$arg.unconfigure = "true"
$esxcli.system.coredump.partition.set.Invoke($arg)
$arg = $esxcli.system.coredump.partition.set.CreateArgs()
$arg.unconfigure = "false"
$arg.enable = "true"
$arg.smart = "true"
$esxcli.system.coredump.partition.set.Invoke($arg)

3	$arg = $esxcli.system.coredump.partition.set.CreateArgs()

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

$srv = Get-VMHost ESXiHost
$esxcli = Get-EsxCli -VMHost $srv -V2
$arg = $esxcli.system.coredump.partition.set.CreateArgs()
$arg.unconfigure = "true"
$esxcli.system.coredump.partition.set.Invoke($arg)
$arg = $esxcli.system.coredump.partition.set.CreateArgs()
$arg.unconfigure = "false"
$arg.enable = "true"
$arg.smart = "true"
$esxcli.system.coredump.partition.set.Invoke($arg)

4	$arg.unconfigure = "true"

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

$srv = Get-VMHost ESXiHost
$esxcli = Get-EsxCli -VMHost $srv -V2
$arg = $esxcli.system.coredump.partition.set.CreateArgs()
$arg.unconfigure = "true"
$esxcli.system.coredump.partition.set.Invoke($arg)
$arg = $esxcli.system.coredump.partition.set.CreateArgs()
$arg.unconfigure = "false"
$arg.enable = "true"
$arg.smart = "true"
$esxcli.system.coredump.partition.set.Invoke($arg)

5	$esxcli.system.coredump.partition.set.Invoke($arg)

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

$srv = Get-VMHost ESXiHost
$esxcli = Get-EsxCli -VMHost $srv -V2
$arg = $esxcli.system.coredump.partition.set.CreateArgs()
$arg.unconfigure = "true"
$esxcli.system.coredump.partition.set.Invoke($arg)
$arg = $esxcli.system.coredump.partition.set.CreateArgs()
$arg.unconfigure = "false"
$arg.enable = "true"
$arg.smart = "true"
$esxcli.system.coredump.partition.set.Invoke($arg)

6	$arg = $esxcli.system.coredump.partition.set.CreateArgs()

Reactivate the coredump, because we deactivated it before:

$srv = Get-VMHost ESXiHost
$esxcli = Get-EsxCli -VMHost $srv -V2
$arg = $esxcli.system.coredump.partition.set.CreateArgs()
$arg.unconfigure = "true"
$esxcli.system.coredump.partition.set.Invoke($arg)
$arg = $esxcli.system.coredump.partition.set.CreateArgs()
$arg.unconfigure = "false"
$arg.enable = "true"
$arg.smart = "true"
$esxcli.system.coredump.partition.set.Invoke($arg)

7	$arg.unconfigure = "false"

Enable the coredump partition:

$srv = Get-VMHost ESXiHost
$esxcli = Get-EsxCli -VMHost $srv -V2
$arg = $esxcli.system.coredump.partition.set.CreateArgs()
$arg.unconfigure = "true"
$esxcli.system.coredump.partition.set.Invoke($arg)
$arg = $esxcli.system.coredump.partition.set.CreateArgs()
$arg.unconfigure = "false"
$arg.enable = "true"
$arg.smart = "true"
$esxcli.system.coredump.partition.set.Invoke($arg)

8	$arg.enable = "true"

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

$srv = Get-VMHost ESXiHost
$esxcli = Get-EsxCli -VMHost $srv -V2
$arg = $esxcli.system.coredump.partition.set.CreateArgs()
$arg.unconfigure = "true"
$esxcli.system.coredump.partition.set.Invoke($arg)
$arg = $esxcli.system.coredump.partition.set.CreateArgs()
$arg.unconfigure = "false"
$arg.enable = "true"
$arg.smart = "true"
$esxcli.system.coredump.partition.set.Invoke($arg)

9	$arg.smart = "true"

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

$srv = Get-VMHost ESXiHost
$esxcli = Get-EsxCli -VMHost $srv -V2
$arg = $esxcli.system.coredump.partition.set.CreateArgs()
$arg.unconfigure = "true"
$esxcli.system.coredump.partition.set.Invoke($arg)
$arg = $esxcli.system.coredump.partition.set.CreateArgs()
$arg.unconfigure = "false"
$arg.enable = "true"
$arg.smart = "true"
$esxcli.system.coredump.partition.set.Invoke($arg)

10	$esxcli.system.coredump.partition.set.Invoke($arg)

Reconfigure diagnostic partition

Reconfigure diagnostic partition with PowerCLI using Get-EsxCli

The following Get-EsxCli command will unconfigure your diagnostic partition and reconfigure with smart selection. This was needed because the install partition uuid had changed due to an option in the NetApp system while doing system testing.

$server_list = Get-VMhost

Foreach ($srv in $server_list)
{
 $esxcli = Get-EsxCli -VMhost $srv
 #$esxcli.system.coredump.file.add($null,"VMFS_log_partition","$srv.name",$null)
 $esxcli.system.coredump.partition.set($null,$null,$null,$true)
 $esxcli.system.coredump.partition.set($true,$null,$true,$null)
 $esxcli.system.coredump.partition.get()
}

$server_list = Get-VMhost

Foreach ($srv in $server_list)

{

$esxcli = Get-EsxCli -VMhost $srv

#$esxcli.system.coredump.file.add($null,"VMFS_log_partition","$srv.name",$null)

$esxcli.system.coredump.partition.set($null,$null,$null,$true)

$esxcli.system.coredump.partition.set($true,$null,$true,$null)

$esxcli.system.coredump.partition.get()

}
