Script to check the correct resource pools
Hi guys
Hoping someone can help with PowerCLI issue?
I want to set up a script PowerCLI who together share CPU and memory allocated to all VMS in each Resource Pool, add them together and compare them with resource information in the list of resources and those who differ from a CSV output (including how on every property is different).
The idea is that this script will quickly check through our vast domain for incorrectly configured in the resource pools (ie. those who have not been updated).
Anyone able to help give advice on how I can get that data into PowerCLI from the pool of resources and the virtual computer?
Thank you very much

I don't know if the values you provide are correct for what is planned.
Especially the MaxCpuUsage won't say much because this will normally reflect the total amount of CPU resources on the host (provided that the customer has no defined limits).
The following should give a better picture (I guess)
$dcName =$report = @() $dc = Get-View -ViewType Datacenter -Filter @{"Name"=$dcName} Get-View -ViewType ResourcePool -SearchRoot $dc.MoRef | where{$_.Name -ne "Resources"} | %{ $rp = $_ $rpMem = 0 $rpCpu = 0 Get-View -ViewType VirtualMachine -SearchRoot $rp.MoRef | %{ $rpMem += $_.Summary.QuickStats.hostMemoryUsage $rpCpu += $_.Summary.QuickStats.overallCpuUsage } $report += New-Object PSObject -Property @{ Name = $rp.Name "VmCpuTotal (MHz)" = $rpCpu "VmMemTotal (MB)" = $rpMem RpCpu = $rp.Runtime.Cpu.UnreservedForVm RpMem = $rp.Runtime.Memory.UnreservedForVm / 1MB } } $report | Export-Csv "C:\ResPool.csv" -NoTypeInformation -UseCulture
Note that this does not overcommitment account. To have the script must use the unreservedForPool rather than the UnreservedForVm property property.

PC telling me to install the network hardware and check the correct drivers is loaded
I just installed Windows vista and I can not get Internet. He tells me to install any network hardware and check the correct drivers are loaded. I'm not smart with computers and jargon. So if anyone can help with this question, it would be appreciated. Thank you
Go to the website of the manufacturer of your computer/laptop > drivers and downloads Section > key in your model number > look for the latest Vista drivers > download/install them.
If you have problems on which to install, contact the manufacturer of your computer.
See you soon.

Move a guest to the different resource pool
I have a box of ESXi 4.1 stand alone. Like a fool when it was created, I don't create pools of resources. Now that more added, I started using pools of resources. I tried to find info on the passage of the guests to a pool different and found that it could be issues (kb/1018360) but cannot find how to actually move a guest. Any ideas?
You can only select and drag the virtual computer to the new resource pool

Using Script to check the version of Adobe Reader software
Hello. I am now currently using LiveCycle Designer to create a form that allows users to attach attachments. We found that if a user uses Adobe Reader 7.0 or below, there is a problem on fixing attachments. Accordingly, we would like to add a script to check the version of the Adobe Reader client in a ready state of the form. If a user uses Adobe 7.0 or below, the message box opens and suggests the user to download a more recent version of the Adobe Reader software. I would like to know is possible to do so. Thank you very much
Hello
the script might look like:
If (typeof (app.viewerVersion)! = "undefined")
If (app.viewerVersion<>
{
xfa.host.messageBox ("your Version of Adobe Reader is old...");
}
}
You can use it in the docReady:Event of your form to inform users.

Is there if a VMS resource pool has enough resources available to start the virtual machine WITHOUT triggering an error of vSphere PowerCLI script - or a series of commands - which can be used to determine?
For reasons of performance test, we use a pool of resources with maximum rates for RAM and CPU. Each virtual machine in the pool has a reservation for CPU and RAM. Test automation will try to start VMs as much as possible in the pool during the test. The CLI will return an error when you start the virtual machine may exceed the amount of allowed resources. When this happens, an error on the console vSphere "insufficient resources". Instead of constantly from the virtual machine, fault and generates error - is there a way to check to see if there is enough space?
Thank you
Jason
Hi Jason,
You can try if the following PowerCLI function is what you need. The function does not resemble stretch bookings.
function Get-VmStartPossible { param($VM) $VM = Get-VM $VM $ResourcePool = $VM | Get-ResourcePool $CpuReservationUsed = $ResourcePool.ExtensionData.Runtime.Cpu.ReservationUsed $VMCpuReservation = $VM.ExtensionData.ResourceConfig.CpuAllocation.Reservation $ResourcePoolCpuLimit = $ResourcePool.ExtensionData.Config.CpuAllocation.Limit $MemoryReservationUsed = $ResourcePool.ExtensionData.Runtime.Memory.ReservationUsed $VMMemoryReservation = $VM.ExtensionData.ResourceConfig.MemoryAllocation.Reservation $ResourcePoolMemoryLimit = $ResourcePool.ExtensionData.Config.MemoryAllocation.Limit*1MB if (($CpuReservationUsed + $VMCpuReservation -gt $ResourcePoolCpuLimit) -or ($MemoryReservationUsed + $VMMemoryReservation -gt $ResourcePoolMemoryLimit)) { $false } else { $true } }
You can call the function with:
Get-VmStartPossible -VM MyVM

Script to check the DRS VM groups?
Hello guys,.
I want to know if you could give me an idea on how to check the DRS of VM groups on my cluster.
DRS group are created with a shared identifier that is common on the VM too. For example: VMS DRS group R125 must include each VM name "R125" is included (such as VM-R125-001).
First of all, I would like to work on a script that will be able to detect if certain VM are not in their groups of DRS corresponding VM (by listing for example) and later add an e-mail notification if possible.
I would like to know if you could give me some advice on how to run this script, what cmdlet should I use, etc.
Thank you very much
Kind regards
Benedict.
EDIT: VM DRS group and not of DRS rules
Try like this
Import-Module DRSRule
#
# Specifications cluster
$cluster1 = "ClusterName".
$cluster = get-Cluster-name $cluster1
#
#for each customer ID.
foreach ($Group in (Get-DrsVMGroup-Cluster $cluster))
{
# Get all the virtual machines that match the groupID
$vms = get-VM-name 'vm-$($Group.Name)-01"- location $cluster | Select name
# Compare 2 results
$result = compare-Object - referenceobject $Group.VM - DifferenceObject $vms
# Display the result
Write-Output "missing DRS rule $([string]: join (($result |))). where {$_.} SideIndicator - eq "=>"} | Select ExpandProperty - InputObject,)' | ')) »
Write-Output "be deleted from the rule DRS $([string]: join (($result |))). where {$_.} SideIndicator - eq '<='} |="" select="" -expandproperty="">='}>

Script to check the version of Cisco VEM on ESXi host
Hallo,
I need help, a script to check and report in a CSV file, the version of Cisco Nexus 1000v VEM on all ESXi hosts connected to a vCenter.
Basically, "vem version - v" but for all the ESXi hosts connected to a vCenter.
Thank you
Joseph
I suspect you could use PowerShell v1, in this version that the Export-Csv has not had the UseCulture parameter.
Try to run the script without this parameter.
But I would strongly suggest to upgrade your version of PowerShell (v3 is available)

Keep the host resource pools after leaving a cluster
I thought is was impossible to keep existing or cluster transplant pools of resources on the host which prefabricated a cluster.
However, vSphere resources management Guide of reading I found an interesting note:
Make sure that you remove the cluster host by placing first in maintenance mode. If you
instead disconnect the host before you delete the cluster, the host keeps the pool resource that
reflects the hierarchy of the cluster.It looked like something, so I tried it but no luck, the host had no pool after removed offline.
Now I'm confused of what this phrase actually means.
What do you see when you connect with vSphere client directly?
Usually, I see ONLY the list of the running virtual machine resources... not all resource pool.
Without virtual machines so I think that all the resource pools are removed.
Try to disconnect with some VM running (also false VMs).

PowerCLI script to check the setting of syslog on a whole cluster?
Hey guys,.
I'm looking for a way to check the setting configured for syslog remote on a large cluster of ESXi. Is it possible to easily check by cluster?
Thanks in advance,
The following PowerCLI script will give you the servers remote syslog for all hosts in a cluster:

Where information on permissions, folders, and the stored resource pools?
Hello world
Lets guess a virtual Center 2.5 with some ESX 3.5, resource pools, clusters of somes, folders with permissions for some users
I would like to know where is the information about files, resource pools, permissions and other stored data. In the registry in VC in .ini files?
The fact is that we are going to migrate to a new Virtual Center but we want to preserve the information on the Organization to avoid retyping all the data again.
Thanks in advance
Hello Luis_F,
Files, Resource Pools, etc. are stored in the database to the virtual Center. Here is a link to a diagram of the U2 virtual Center 2.0.2 schema. There are of course changes in 2.5, but the diagram can help out you.

SQL script to check the status of the last command

It works perfectly, but my problem is that if a command fails, the other controls in suite works. However, I need to keep a check when a broken command that you exit the script.
On unix, we have an option of echo $? to check the status of the previous command, but how to accomplish this SQL.
Pls help!
