HP’s September VMware driver bundle and issues with Emulex CNA’s


Update 08/10/2014: HP support recommends to install the following versions of the Emulex firmware/drivers.

Install the following driver and firmware version for the NIC and install on server and check

As it is a ESX 5.1 we would use BE2NET driver

Driver: 4.9.488.0 – http://www.hp.com/
Firmware: 4.9.416.0 – http://www.hp.com/

You can read more about the issues here at http://www.techazine.com. I saw the same symptoms on brand new HP BL460 Gen8 and vSphere 5.1 update 2, the latest build: VMware-ESXi-5.1.0-Update2-2000251-HP-5.68.30-Sep2014.iso released on 2014-09-08.  Hosts randomly disconnects from vCenter, even if those hosts are in maintenance mode (lucky me).

The driver causing the issues is version: net-be2net 10.2.293.0-1OEM.510.0.0.802205 Emulex VMwareCertified 2014-08-25. More information about the drivers included in the latest custom ISO can be found here: http://vibsdepot.hp.com/hpq/recipes/September2014VMwareRecipe16.0.pdf

To solve this issue, you need to downgrade the driver to the previous version. I had no issues with the 4.6.247.10 drivers so I used this one.

I created a PowerCLI script to verify the installed version of the net-be2net on all the BL460c Gen8 blades.

$be2netlist = @()
foreach($vmhost in (Get-VMhost | ?{$_.Model -eq "ProLiant BL460c Gen8"}| sort name)){
    Write-Host "Checking host $($vmhost.name)" -ForegroundColor Yellow
    $esxcli = Get-EsxCli -VMHost $vmhost
        $be2net = New-Object PSObject -Property ([ordered]@{
            vmhost = $vmhost.name
            driver = ($esxcli.software.vib.list() | ?{$_.Name -eq "net-be2net"}).name
            version = ($esxcli.software.vib.list() | ?{$_.Name -eq "net-be2net"}).version        
        })
        $be2netlist += $be2net
}
$be2netlist | ft -AutoSize

The output:

Now we wait for a fix from HP and Emulex.

Slow mouse performance on Windows 2008 R2 virtual machine


I wanted to migrate the lab to Windows Server 2008 R2 and found some problems with the video drivers provided with vSphere 4.0. After a quick search at http://kb.vmware.com I found the following KB article: KB1011709. This article mentioned the new WDDM driver:

Troubleshooting SVGA drivers installed with VMware Tools on Windows 7 and Windows 2008 R2 running on ESX 4.0

Details
  • You receive a black screen on the virtual machine when using Windows 7 or Windows 2008 R2 as a guest operating system on ESX 4.0.
  • You experience slow mouse performance on Windows 2008 R2 virtual machine.
Solution

This issue can occur due to the XPDM (SVGA) driver provided with VMware Tools. This is a legacy Windows driver and is not supported on Windows 7 and Windows 2008 R2 guest operating systems.

To resolve this issue, update to ESX 4.0 Update 1. A new WDDM driver is installed with the updated VMware Tools and is compatible with Windows 7 and Windows 2008 R2.

Note: After a VMware Tools upgrade, the driver files are located in C:\Program Files\Common Files\VMware\Drivers\wddm_video.

Script: Install Printer Drivers On TS/Citrix Servers


Aleks van http://www.virtualistic.nl/ heeft een script geschreven voor het installeren van Printer drivers op een Terminal / Citrix server. Ik was de gelukkige betá tester (zonder problemen) en alles werkte out of the box.

Hieronder een quote van de website van Aleks:

Prerequisites:
– You have to be able to install printdrivers (duh!)
– You have to be able to connect to your printerserver (test this through typing \\yourprintserver you should see your shared printers)
What is inside the zip file?
– The script of course!
– Addprinters.txt this is the input file for the script. Place your printers in this .txt file (eg: \\yourprintserver\printer1)
The default location of the addprinters.txt is C:\ You can change this but make sure you edit the script to reflect the new location.

Zodra je het Addprinters.txt hebt gevuld, start je het script en dan verschijnt het onderstaande scherm.

PrinterDriver_Script

Nu ben je natuurlijk benieuwd wat het script gedaan heeft. Dat laat ik zien in de onderstaande tekening:
