Need to run script/python command against ESXi hosts

PSScripter — Mon, 15 May 2023 11:08:14 GMT

Hello,

I need to run the following commands against 2 clusters of hosts, 26 in total, all contained in 1 VC:

mv /vmfs/volumes/WB01-INF03-PMAX-DS01/ucs-tool-esxi_1.2.1-1OEM.zip /tmp

esxcli software component apply -d /tmp/ucs-tool-esxi_1.2.1-1OEM.zip

python /opt/ucs_tool_esxi/ucs_host_inventory.py

Can anyone point me in the right direction to do this in PS? I dont want to ssh into all of the hosts. Thank You!

The esxcli command you can do via the Get-EsxCli cmdlet, for the mv and python commands you will need to use SSH I'm afraid.
With the Posh-SSH module you can do that from your script.

See for example Use Posh-SSH instead of PuTTY

Here is what I came up with, I have not used it yet..but I think it will work

Connect-VIServer 'XXXXXXXXXXXXX' $hosts = Get-Cluster "XXXXXXXXXX" | Get-VMHost $cred = Get-Credential $cmd = "mv /vmfs/volumes/INF03-PMAX-DS01/ucs-tool-esxi_1.2.1-1OEM.zip /tmp" $cmd1 = "python /opt/ucs_tool_esxi/ucs_host_inventory.py" foreach ($host in $hosts) { Get-VMHost $host | Get-VMHostService | Where-Object { $_.Key -eq "TSM-SSH" } | Start-VMHostService $session = New-SSHSession -ComputerName $host -Credential $cred -AcceptKey Invoke-SSHCommand -SSHSession $session -Command $cmd Get-esxcli software component apply -d /tmp/ucs-tool-esxi_1.2.1-1OEM.zip Invoke-SSHCommand -SSHSession $session -Command $cmd1 Remove-SSHSession -SSHSession $session | Out-Null }

Any thoughts on that piece of work lol?

I'm still trying to get this working correctly. Here is my latest, and the error I am getting:

Connect-VIServer 'XXXXXXXXXXXXX' $hosts = Get-Cluster -name "XXXXXXXXXXX" | Get-VMHost $cred = Get-Credential $cmd = "mv /vmfs/volumes/INF03-PMAX-NonProd-DS01/ucs-tool-esxi_1.2.1-1OEM.zip /tmp" $cmd1 = "python /opt/ucs_tool_esxi/ucs_host_inventory.py" $arguments = @{ 'VIBURL' = '/tmp/ucs-tool-esxi_1.2.1-1OEM.zip' } foreach ($esx in $hosts) { # Get-VMHost $esx | Get-VMHostService | Where-Object { $_.Key -eq "TSM-SSH" } | Start-VMHostService $session = New-SSHSession -ComputerName $esx -Credential $cred -AcceptKey Invoke-SSHCommand -SSHSession $session -Command $cmd $esxcli = Get-EsxCli -VMHost $esx $esxcli.software.component.apply.Invoke($arguments) Invoke-SSHCommand -SSHSession $session -Command $cmd1 Remove-SSHSession -SSHSession $session | Out-Null }

The copy seems to work, but the esxcli command is failing with this:

MethodInvocationException: C:\Temp\vSphere\Install-UCSTools.ps1:19 Line | 19 | $esxcli.software.component.apply.Invoke($arguments) | ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ | Exception calling "Invoke" with "1" argument(s): "A specified parameter was not correct: argument[1]"

Any thoughts on how I can get this working?

Thank You.

This seems to work:

Connect-VIServer 'XXXXXXXXXXXXX' $hosts = Get-Cluster -name "XXXXXXXXXXX" | Get-VMHost $cred = Get-Credential $cmd = "mv /vmfs/volumes/INF03-PMAX-NonProd-DS01/ucs-tool-esxi_1.2.1-1OEM.zip /tmp" $cmd1 = "python /opt/ucs_tool_esxi/ucs_host_inventory.py" $arguments = @{ 'VIBNAME' = '/tmp/ucs-tool-esxi_1.2.1-1OEM.zip' } foreach ($esx in $hosts) { Get-VMHost $esx | Get-VMHostService | Where-Object { $_.Key -eq "TSM-SSH" } | Start-VMHostService $session = New-SSHSession -ComputerName $esx -Credential $cred -AcceptKey Invoke-SSHCommand -SSHSession $session -Command $cmd $esxcli = Get-EsxCli -VMHost $esx $esxcli.software.vib.install("/tmp/ucs-tool-esxi_1.2.1-1OEM.zip") Invoke-SSHCommand -SSHSession $session -Command $cmd1 Remove-SSHSession -SSHSession $session | Out-Null }

To use the Invoke method, you have to add the V2 switch

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