PowerCLI: VAMI DNS Change

  • 1.  PowerCLI: VAMI DNS Change

    Posted Apr 26, 2022 08:13 PM

    I've been fighting with it for 3 days, sucking up my pride needed to happen 2 days ago

    I am trying to update the VAMI DNS, using PowerCLI.  I get get the detail:

    $DNSService = Get-CisService -Name "com.vmware.appliance.networking.dns.servers"
    ($DNSService.get()).servers
    1.1.1.3
    1.1.0.3
     
    I can add:
    $DNSService.Add("8.8.8.8")
    ($DNSService.get()).servers
    1.1.1.3
    1.1.0.3
    8.8.8.8
     
    How do I purge the existing content or simply replace the list?  I'm still learning the API content, I hope this is simple.

    Use the set() method, this overwites with what is in mode and servers (which is an array)

    Make sure to first check with the get() method what the mode is set to.

    Perfect!  I was wondering all over looking at how to set the various array details, that was indeed more simple than I was making it.  Thanks!

    Hi Lucd,

    i have tried your Solution with VCSA 8. But it not works..

    see here:

    $dns = Get-CisService -Name 'com.vmware.appliance.networking.dns.servers'

    $dnsservers = "1.1.1.1, 8.8.8.8"

    When i put the variable in the servers String or the String itself is the same result:

    $dns.set(@{mode = 'is_static';servers = @($dnsservers)})

    $dns.set(@{mode = 'is_static';servers = @('1.1.1.1, 8.8.8.8')})

    A server error occurred: 'com.vmware.vapi.std.errors.error': DNS Server: 1.1.1.1, 8.8.8.8 does not appear to be a valid IPv4 or IPv6 address. (Server error
    id: 'com.vmware.applmgmt.err_invalid_dns_servers'). Check $Error[0].Exception.ServerError for more details.
    At line:1 char:1
    + $dns.set(@{mode = 'is_static';servers = @('1.1.1.1, 8.8.8.8')})
    + ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
    + CategoryInfo : OperationStopped: (:) [], CisServerException
    + FullyQualifiedErrorId : VMware.VimAutomation.Cis.Core.Types.V1.CisServerException

    Any Suggestions what i am doing wrong??

    Afaik it should be an array of strings, not a single string

    When i try these i receive an other Error:

    A server error occurred: 'com.vmware.vapi.std.errors.error': Operation Failed. (Server error id: 'com.vmware.applmgmt.err_operation_failed'). Check
    $Error[0].Exception.ServerError for more details.

    Did you also do the get()?
    What is the mode?

    Yes i have done these with a Custom Object:

    $dnsCustom = [PSCustomObject]@{
    Servers = ($dns.get().servers -replace '{}', '') -join ','
    Mode = $dns.get().mode
    }

    Output:

    Servers                              Mode
    -------                                  ----
    3.3.3.3,.4.4.4.4                is_static

    Can you stop/start your PS/PowerCLI session, reconnect to the CisServer and run the code again.

    I had similar issues in the past, a restart and reconnect helped.

    I have restarted the CI Session and also restarted the vCenter itself.

    Same Results

    On a vCenter with Version: 7.0.3 Build: 20150588 it works, but not on vCenter 8.0.0 Build: 20920323

    When I look at the underlying REST API there seems to be a difference in the Body of the method.

    V7 vs V8

    Can you check what the following shows on V8 (I don't have a V8 available yet)?

    You´re right the Body has changed.

    Output is:

    Did you use that snippet I posted earlier, with the 

    That should provide the correct layout of the config object.

    Yes i have used that before

    That should normally return an object with the correct layout for V8 version.
    If it doesn't then there is an issue somewhere.
    You could call the V8 Rest API directly, but you will have to authenticate first.

    Ok Thx, but i have no Tools installed on that JS for API Connections directly like Postman...

    You can use the Invoke-WebRequest or Invoke-RestMethod cmdlets.
