hello everyone
i am designing some simple script to retrieve VM Hard Disk information with PowerCli and i got some pretty weird issue: i ocasionally get runtime execution errors with vc server disconnection, but after the error, i can retrieve info on the same vcenter with simple commands (like Get-VM for instance). The vc farms still available over viclient and powercli all the time, so it must be something on the code
the steps i use to reproduce the strange behavior:
(Using Powercli 5.5 and Powershell 3.0. Error still happens with Powercli 5.1)
- Connect to vcenter (multiple servers)
- run the command and it eventually gets stuck in line 12 ($ghd = Get-HardDisk (Get-VIObjectByVIView $VMView)) with the error 'Server XXXX is disconnected'
- Run some other command (like get-vm) to certify that server is still connected
sample script is below
Function Get-VMDiskInfo {
[CmdletBinding()]
Param (
[Parameter(Mandatory=$true,
ValueFromPipeline=$True,
ValueFromPipelineByPropertyName=$true)]
[Alias('Name')]
$VM
)
PROCESS{
$VMView = Get-View -ViewType VirtualMachine -Filter @{"Name" = $VM}
$ghd = Get-HardDisk (Get-VIObjectByVIView $VMView)
$output = @()
ForEach ($VirtualSCSIController in ($VMView.Config.Hardware.Device | Where {$_.DeviceInfo.Label -match “SCSI Controller”})){
ForEach ($VirtualDiskDevice in ($VMView.Config.Hardware.Device | Where {$_.ControllerKey -eq $VirtualSCSIController.Key})){
$VMSummary = “” | Select VM,Disk, SCSI, DiskType, DiskFormat, DiskSizeGB, DiskFile
$VMSummary.VM = $VM
$VMSummary.SCSI = [string]::Concat($VirtualSCSIController.BusNumber,":",$VirtualDiskDevice.UnitNumber)
$VMSummary.Disk = $VirtualDiskDevice.DeviceInfo.Label
#pegando info do Get-Harddisks
$d = $ghd | ? {$_.Name -match $VirtualDiskDevice.DeviceInfo.Label}
$VMSummary.DiskType = $d.DiskType
$VMSummary.DiskSizeGB = [Math]::Round($d.capacityGB,2)
$VMSummary.DiskFile = $d.filename
if($d.Disktype -eq "Flat"){
$VMSummary.DiskFormat = $d.StorageFormat
}
$output += $VMSummary
}
}
Write-Output $output
}
}
does anyone have any idea whats going on ?
almost forgot, sorry about the messy code and the poor english...
thanks in advance
