Script to Unmanage all hosts in a CSV file

Thank you for posting this. It appears this script requires the Node ID in the CSV file to function. Is there anyway for the script to lookup the NodeID from just the hostname or IP?

A very slick script, up there hopefully someone can answer my question.

The script below works like a charm,

Is there anyway to add a fixed DateTime for $now and $later ?

In other words we have to unmanage the hosts on Fridays at 7pm till Saturday, 1am, unmanaged for 6 hours

Thanks for your help

$Hostname = @()

$NodeID = @()

Import-Csv C:\Scripts\Solarwinds\Hosts.csv | ForEach-Object { $Hostname += $_."Hostname"; $NodeID += $_.NodeID }

$swis = Connect-Swis -host "XXXX" -UserName "xxxx" -Password "xxxx"

For ($i=0; $i -lt $NodeID.length; $i++) {

    $now=[DateTime]::UtcNow

    #$now="Friday, May 11, 2018 7:00:00 PM"

    $later=$now.AddMinutes(5)

    #$later="Saturday, May 12, 2018 1:00:00 AM"

    $NodeIdStr = "N:" + $NodeID[$i]

    $NodeIdStr

    $WhatTime = Invoke-SwisVerb $swis Orion.Nodes Unmanage @($NodeIdStr,$now,$later,"false")

    $WhatTime

    $Hostname[$i]

    $NodeID[$i]

}
