Hi All
I'm putting together a script and I would like it to perform some input validation. It basically needs to compare the name of the clusters in a vcenter and compare it to what the user enters, if the cluster exists it should continue with the name if it doesn't it should print "Invalid cluster name" and ask for input again.
The full script allows the user to connect to one of multiple vcenters and it already works vCenters with only one cluster. However as soon as there is more than one cluster it does not validate any of the names correctly. So basically doesn't deal with the multiple variables in the array correctly.
Below are the snippets from this part of the script. Some help would be greatly appreciated.
Function Test-Cluster {
[CmdletBinding()]
param (
[ValidateScript({
if ($_ -eq $clusters) {
$true
} else {
throw "$_ is an invalid cluster name "
}
})]
$clustername
)
}
# Connect to your vCenter instanceConnect-VIServer -Server $vcentername -Credential $vcenterpw | Out-Null
# Choose a cluster
Write-Output " "
Write-Host "The following clusters are available in the vCenter" -ForegroundColor Green
Write-Output " "
$cluster = Get-Cluster
$clusters = $cluster.Name
$clusters
Write-Output " "
Do {
$clustername = Read-Host -Prompt 'Which cluster contains the resource pool you would like to upgrade?'
Try {
$a = 'no error'
$Error.clear()
$null = Test-Cluster -clustername $clustername
}
Catch {
Write-Host $Error -ForegroundColor Red
$a = 'error'
}
}
While ($a -eq 'error')
