Re: PowerCLI: Migrate VM’s to another VLAN/Portgroup

PIR8 — Mon, 04 Feb 2013 19:01:33 -0000

here is script i wrote to migrate the static IP's based on a conversion table;

if ($file){
$file = Import-Csv $file
}
$iptable = Import-Csv "H:\My Documents\IP_Table.csv"
$interfaces = Get-WmiObject Win32_NetworkAdapterConfiguration | where {$_.DefaultIPGateway -ne $null} | Select DHCPEnabled, IPAddress, IPSubnet, DefaultIPGateway, DNSDomain, DNSServerSearchOrder, ServiceName, Description, Index
Foreach ($interface in $interfaces){
$Interface = Get-WmiObject Win32_NetworkAdapterConfiguration | where {$_.DefaultIPGateway -ne $null}
#$Interface | GM
$gateway = $Interface.DefaultIPGateway
$IPOctect = $Interface.IPAddress[0].split(".")
$iptable | foreach {
#$_ | FT
if ($IPOctect[1] -eq $_.IPOctect1 -and $IPOctect[2] -eq $_.IPOctect2){
Write-Host "$(Get-Date -format T): Found IP Address" $Interface.IPAddress #"in table:" $_.IPOctect[0] $_.IPOctect[1] $_.IPOctect[2] $_.IPOctect[4]
#Concatenate IP
$dot = "."
$NewIP = $_.New_IPOctect0 + $dot + $_.New_IPOctect1 + $dot + $_.New_IPOctect2 + $dot + $IPOctect[3]
$gateway = $_.New_IPOctect0 + $dot + $_.New_IPOctect1 + $dot + $_.New_IPOctect2 + $dot + "1"
$subnet = $Interface.IPSubnet[0]
Write-Host "$(Get-Date -format T): Setting IP Address to $NewIP"
Write-Host "$(Get-Date -format T): Setting Gateway Address to $gateway"
Write-Host "$(Get-Date -format T): Setting subnet to $subnet"
Write-Host "$(Get-Date -format T): Setting DNS: $dns for $site"
Write-Host "$(Get-Date -format T): Registering DNS"
$Interface.EnableStatic($NewIP, $subnetmask)

get-vmhoststorage can take pipeline input... no need for the foreach loop.

Sorry, zie je comment nu pas :) Heb het erg druk en gebruik geen scripts daarvoor, wij monitoren onze datastores in Nagios.

Laurens,

Wij kennen elkaar van XTG Gouda.
Ik heb een omgeving 4 Hosts. vSphere 4.
Wil graag elke maand automatisch een diskgebruik hebben.

Een XLS rapportage van alle VM's en hun disk gebruik en wat er vrij is.
Zodat we over 4 jaar een mooie rapportage kunnen geven in exl wat het verbuik geweest is.

Heb jij een PowerCLI op de plank liggen ?

I installed the 512MB cache module with the battery backup unit, but I'm still experiencing AWFUL disk read/write performance. I'm running ESXi 4.1 U2. I've installed all of the latest firmware updates (Firmware DVD 9.30 plus the Service Pack disk from September 2011).

When I "F8" into the controller setup at boot, I don't see any options to verify/adjust the cache settings, so is there another way to do this?

This script definitely good. But some information missing. It would be great if the output has total CPU and Total Memory along with the current utilization.

Hi gabrielpc1190,

Buy a Battery Kit upgrade (for BBWC) 462969-B21.

Attach this to the connector on the cache and when the battery charges (may be 30mins to 2 hrs) then all will be fine.

If you are going to turn on Physical Drive Write Cache State make sure you have the server running off a UPS otherwise you may lose data on a unscheduled power outage.
I recommend that all servers should be on a suitable sized UPS with the monitoring/remote shutdown software installed.
It amazes me how many servers I see attached to UPS with no monitoring/remote shutdown software installed.
o.O

Hi,

Very nice skript.
Is it also possible to get the Cluster from this VM Host in the same skript?
So that i have the rows: VMHostName, ClusterName, OverallStatus, CPU Usage, Memory Usage

And it would be also great if i have a row with Host count.

Julio :
I’m planning on buying an HP DL380 G6 and will use vmware ESXi 4.0 too with 3 VM (2 with Windows Server 2008 + 1 Linux) so this issue concerns me very much.
The model that is on stock right now in my country (Argentina) is 491324-001 which includes HP Smart Array P410i/256MB Controller.
What are my options? HP recommends 1) 512MB BBWC 462967-B21 2) Battery Kit upgrade (for BBWC) 462969-B21 3) 256MB Cache Module 462968-B21. But I’m not sure which one is for me. Do I need 512MB BBWC for use Battery Kit upgrade (for BBWC) 462969-B21?
I would appreciated your help.

Did you get this resolved?
I want to upgrade my server too but i dont know what i have to buy. I have the Smart Array P410i/256MB Controller too.
Thanks

Thanks for posting the code for your utility. It helps having a VMware related example in figuring out how powershell code fits into the PrimalForms GUI generated templates.

Re: VMware vCenter Server Heartbeat

denicklor — Mon, 20 Dec 2010 05:57:06 -0000

"In our case this is Windows Server 2008 x64 Standard. Give it a temporary IP (DHCP if you will) and a bogus hostname. This will be overwritten when Heartbeat sets up your secondary node with your primary node’s data. Both: also make sure you have your ILO configuration on both the primary as the secondary server to be able to reach the servers in some of the steps of the installation Both: make sure the Windows Update level on both servers is the same. Both: in case you are using Windows Server 2008 you need to install some features on the server before you can start the installation: Backup, Backup-Features and Backup-Tools. Both: Very important, installing Heartbeat will NOT work properly when you have NIC Teaming enabled. If you want to use NIC Teaming: set it up when the whole Heartbeat setup is finished! Primary: install Heartbeat and follow the steps on the screen, make sure you have some storage space on the network available to store the temporary backup-files to transfer the backup which contains the identity of your primary server to your secondary.Important: make sure your secondary server is able to reach this location. Secondary: as you probably have followed all of the steps on your primary node the setup will tell you to continue your setup on your Secondary node. Secondary: don’t forget to manually change your Channel IP to the proper IP you have reserved for the secondary node after the Heartbeat setup rebooted your server! Both: this is for both servers, but has to be configured only once in your Heartbeat configuration. You will need to provide a service account to the vCenter Service Plugin of Heartbeat that has enough access on your vCenter Server to monitor if it’s down or up.I would suggest if you are running vCenter Server on a service account like I do you use that account for this purpose."
You can out more?

Guys
dont buy this.... Is a piece of s****. Customer has TWO licenses, and from month of using this product in production was HB working normally week i think. Everything was fine, until we try to patch operating system (MS Update). We use official KB (http://kb.vmware.com/kb/101... but of course this doesnt work and after that starts our problems. Now we are solving these with support third week and im crazy about it.....

good luck

Vincent — Thu, 22 Jul 2010 09:11:26 -0000

I'm running vC HB 6.3 on W2k8 R2 in a test lab. I've two questions

1. How do i keep the passive secondary vCenter HB server up to date. E.g. Anti virus, MS updates, etc. Is it possible to sync the whole primary server so when a failover has occured, the whole secondary HB server is complete synchronized?

2. When I try to connect the vCenter Heartbeat server on a computer(Only Heartbeat console cliënt installed) other then the vCenter Heartbeat Server we receive the following message:

Connection refused to host: ; nested exeception is: jave.net.ConnectException: Connection timed out

We opened tcp port 52267 in the firewall. We tried it on a XP SP3 and a Windows 2008 Cliënt. On the vCenter Heartbeat Server 6.3 server(s) the Heartbeat console works normal.

The biggest downside of VCSHB is the license cost - it's twice as much as the software it protects...

MSCS is officially not supported by VMware to make your vCenter redundant.

Hi,

Thanks for this helpful article.

I had forgotten all about this product, seems to not get my press compared to others in the VMware line.
But defiantly needs more considering when comparing to MSCS for HA.

There's a WAY easier way to do this, just right click the setup executable, choose the "Compatability" tab, and just tell it to do the install as if it was Vista SP2. Boom, requirement check passed!

I had exactly the same problem.

Only firmware updates will not solve the problem.

I bought a 512mb bbwc controller (pn: 462967-B21) and my transfer rate was great.
In stead of 2 / 3 MB/s i've got now 70 till 100 MB/s disk transfer speed on my local disks.
