Hi,
I'm using this code to export DRS-Rules.
1. The data is exporting fine (if the script is executed manually), but the console is still throwing the errors (screenshot below, also attached with this post)
2. The script doesn't export any data if I schedule the same from windows task scheduler.
Please let me know how to address the above.
Code:
## get cluster .NET view objects, which hold the info about the DRS rules
Get-View -ViewType ClusterComputeResource -Property Name, ConfigurationEx | %{
## if the cluster has any DRS rules
if ($_.ConfigurationEx.Rule -ne $null) {
$viewCurrClus = $_
$viewCurrClus.ConfigurationEx.Rule | %{
$oRuleInfo = New-Object -Type PSObject -Property @{
ClusterName = $viewCurrClus.Name
RuleName = $_.Name
RuleType = $_.GetType().Name
RuleEnabled = $_.Enabled
Mandatory = $_.Mandatory
} ## end new-object
## add members to the output object, to be populated in a bit
"KeepTogether,VMNames,VMGroupName,VMGroupMembers,AffineHostGrpName,AffineHostGrpMembers,AntiAffineHostGrpName,AntiAffineHostGrpMembers".Split(",") | %{Add-Member -InputObject $oRuleInfo -MemberType NoteProperty -Name $_ -Value $null}
## switch statement based on the object type of the .NET view object
switch ($_){
## if it is a ClusterVmHostRuleInfo rule, get the VM info from the cluster View object
# a ClusterVmHostRuleInfo item "identifies virtual machines and host groups that determine virtual machine placement"
{$_ -is [VMware.Vim.ClusterVmHostRuleInfo]} {
$oRuleInfo.VMGroupName = $_.VmGroupName
## get the VM group members' names
$oRuleInfo.VMGroupMembers = (Get-View -Property Name ($viewCurrClus.ConfigurationEx.Group | ?{($_ -is [VMware.Vim.ClusterVmGroup]) -and ($_.Name -eq $oRuleInfo.VMGroupName)}).Vm | %{$_.Name}) -join ","
$oRuleInfo.AffineHostGrpName = $_.AffineHostGroupName
## get affine hosts' names
$oRuleInfo.AffineHostGrpMembers = if ($_.AffineHostGroupName -ne $null) {(Get-View -Property Name ($viewCurrClus.ConfigurationEx.Group | ?{($_ -is [VMware.Vim.ClusterHostGroup]) -and ($_.Name -eq $oRuleInfo.AffineHostGrpName)}).Host | %{$_.Name}) -join ","}
$oRuleInfo.AntiAffineHostGrpName = $_.AntiAffineHostGroupName
## get anti-affine hosts' names
$oRuleInfo.AntiAffineHostGrpMembers = if ($_.AntiAffineHostGroupName -ne $null) {(Get-View -Property Name ($viewCurrClus.ConfigurationEx.Group | ?{($_ -is [VMware.Vim.ClusterHostGroup]) -and ($_.Name -eq $oRuleInfo.AntiAffineHostGrpName)}).Host | %{$_.Name}) -join ","}
break;
} ## end block
## if ClusterAffinityRuleSpec (or AntiAffinity), get the VM names (using Get-View)
{($_ -is [VMware.Vim.ClusterAffinityRuleSpec]) -or ($_ -is [VMware.Vim.ClusterAntiAffinityRuleSpec])} {
$oRuleInfo.VMNames = if ($_.Vm.Count -gt 0) {(Get-View -Property Name $_.Vm | %{$_.Name}) -join ","}
} ## end block
{$_ -is [VMware.Vim.ClusterAffinityRuleSpec]} {
$oRuleInfo.KeepTogether = $true
} ## end block
{$_ -is [VMware.Vim.ClusterAntiAffinityRuleSpec]} {
$oRuleInfo.KeepTogether = $false
} ## end block
default {"none of the above"}
} ## end switch
$oRuleInfo
}
} ## end if
} ##end get-view
