Get Dell iSM & PTAgent Versions with PowerShell?

I need to get the iSM and PTAgent versions from AHV clusters running on the Dell XC platform using PowerShell cmdlets. Does anyone know if this is possible? I can’t figure it out and do not think it is possible at this point.

Yes, you can use this to get firmware information from the PTAgent. I susscessfully did it after importing the SSHSessions module. Sample below:


$CvmCredentials = Get-Credential
$CvmCredentials | Export-Clixml -Path "${env:\userprofile}\CVM.cred"

$CvmCredentials = Import-Clixml -Path "${env:\userprofile}\CVM.cred"

$CvmIP = “x.x.x.x”

New-SshSession -ComputerName $CvmIP -Credential $CvmCredentials

$Inventory = Invoke-SshCommand -ComputerName $CvmIP -Command "curl -s -k H 'Content-Type:application/json' -X POST '' --data {} | less"
$Inventory = $Inventory.result | ConvertFrom-Json


Now you can dig through the $Inventory object and grab whatever you need. For example, $inventory.iDRAC will display all the properties of the iDRAC, like firmware version. Pretty much anything that LCM displays or updates is available here.

@sedwards, Hahaha! Wow, I’m a dummy. Okay, so I don’t know what I was thinking but I was connecting into the CVM instead of AHV for some reason (Using the SSHSessions module) and after connecting into AHV insteadI was able to pull the information I was looking for. Thanks!

Now I wonder if I can use this on the CVM to connect to the PTAgent and pull firmware data instead of creating a cim-session directly to the iDRAC and pulling everything. Might be faster or at least use it as a backup in the event I can’t establish a cim-session.

@sedwards, okay, so this is actually getting me somewhere, sort of. I downloaded the module and was able to successfully establish an ssh session to a CVM via PowerShell. However, it looks like it only supports certain commands, like “ls” or “df -h”. If I try to run something like “genesis status” then it comes back with “[cvm ip] had an error: bash: genesis: command not found.” But running a “hostname” command will return me back the CVM name and like I said above, df -h works and ls works so I am sure other common linux commands work too but nothing specific to Nutanix seems to function, unfortunately.

Similar result if I try to do a cluster status. I get “[cvm ip] had an error: bash: cluster: command not found”

I don’t think I’ll be successful at getting PTagent or iSM versions if I can’t even pull a simple cluster status. I guess it is quite possible I am doing something wrong though.


Hi Jason,


There’s no Winrm interface on the AHV hosts for powershell to talk to. We use rpm commands run on the ahv hosts to get that version information manually, like this:

rpm -qa | grep -i ism


rpm -qa | grep -i ptagent DellPTAgent-1.3-0.7940.x86_64  

You would need to be able to ssh to the ahv hosts and run above commands and capture the output in your powershell script. 


I found this guy’s blog that seemed relevant to this topic:



These nodes are all running AHV, not Hyper-V. Don’t think this will work.


Also, I need to be able to pull the information with the Nutanix PowerShell cmdlets so the results can be sent to a spreadsheet with a ton of other information I’m gathering. I’m managing hundreds of nodes and need to automate wherever I can.

Hi @JasonStenack 

Please check the command below, this should get you started. 

Get-ChildItem -Path HKLM:\SOFTWARE\Microsoft\Windows\CurrentVersion\Uninstall | Get-ItemProperty | Where-Object {$_.DisplayName -match 'DellPTAgent'} | Select-Object DisplayVersion, DisplayName, InstallDate | ConvertTo-Json

If this does not work, I suppose you are hitting an issue we have noticed where LCM fails to populate the ISM and PTAgent versions due to python version being installed automatically is a 32 bit process and the DELL’s PTAgent/ISM is a 64 bit installation when done manually.

Let me know if this help !!
