Bring Your Own Cloud

Daniel de ZoeteComments Off on Bring Your Own Cloud

File:OwnCloud2-Logo.svgIn the category “Sumble Upon”, I came across a nice piece of software which let you forget about Dropbox, SkyDrive, GDrive, etc. Because now you can build your storage-cloud on premises.

Nowadays there is a proliferation of providers, if you want some storage in the cloud to store your photos, videos, documents, etc. And as always every provider has its own advantages and limitations.

Now we could use a Synology NAS or a Pogoplug to create a storage-cloud on premises, but we want to be in control and we want to try, play and experience building our own storage-cloud. It’s just like version 2 of building our own NAS, not just buy a NAS but build one with OpenFiler or FreeNAS.

We all know the little blue bar in VMware that tells us the progress of an action. But what does the percentages mean and what is the problem when the action fails at a certain percentage?

Some people also know shortcuts regarding the windows shell, like Windowskey+E to open the explorer and CTRL+SHIFT+ESC to open the taskmanager. Many of this shortcuts stay the same in every version of Windows and sometime new shortcuts are added.

With the introduction of Windows 8, Microsoft also introduced some new shortcuts and in my opinion essential to know when want to work with Windows 8 in corporate environment. My personal favorite is Windowskey+X.

So here is a list of new shortcuts for Windows 8 that I know of: Continue reading »

Snapshots present and growing, but not visible in Snapshot Manager

Daniel de ZoeteComments Off on Snapshots present and growing, but not visible in Snapshot Manager

When using  a backup solution for your virtual environment and the database-server for this backup solution is also situated in the virtual environment, you have to face some challanges. The backup solution cannot back up its own database, while using it. Luckily there are work-a-rounds covering this particular problem. But what happens if you misconfigured this work-a-round? In this case snapshots will be taken of the database-server and will not get removed properly, resulting in snapshots on your datastore that keep growing and growing and you will not be aware of it, because the snapshot manager says there are no snapshots present.

Deployment ESXi with duplicated MAC-addresses

Daniel de ZoeteComments Off on Deployment ESXi with duplicated MAC-addresses
After deploying new ESXi 4.1 hosts trough Altiris and adding them to the Virtual
Center Server, I saw that some of the hosts repeatedly were being disconnected
and connected again. Also the new hosts were not reachable from the network.

At first we thought of network problems although other servers in the datacenter did not
experience this sort of problems. Continue reading »

VMFS permission Access denied and VM’s are running.

Daniel de Zoete, Marco DrostComments Off on VMFS permission Access denied and VM’s are running.

In a upgrade process form ESX 4.0 to ESXi 4.1 we reinstalled a Blade servers(BL 460c G6) by script. In our update process steps there is a step Un-present all LUN that are presented to the related host. This is done to be sure that the installation will not install on a LUN that is presented. And here is where the human factor kicked in we forgot 1 LUN the was presented to the host. This was a LUN that was presented form the Test and Development  environment and this was temporally but not temporally  enough 🙁 So when running the installation script he saw that LUN (CLUN002)  as the first disk and in the script it says install on first disk See this article. In the beginning we did noticed that the installation failed but with a adjustment of the script it worked. And all Virtual machine just keep running. The next morning all look well until some of the virtual machine went for a planed reboot and did not come up any more. At this point we know we had a storage issue because the rebooted virtual Machines gave a Orphaned error. Some machine where not rebooted and could not be accessed though the vCenter Console option but could be accessed through RDP and where alive and well.

Scripted install VMware ESXi on HP Blade hardware

Daniel de Zoete, Marco DrostComments Off on Scripted install VMware ESXi on HP Blade hardware

Today we got to the second stage of upgrading the customer VMware environment. The first stage was the test and Development cluster. This cluster consists 6 HP DL 380 G5 rack mounted servers and with the install script we have made it was a peace of cake! In stage 2 we upgrade (by reinstallation) a part of the production environment when we did the scripted installation all looked well installation process in running writing his image reboot and then the blade server booted the old ESX 4.0 installation instead of the new ESXi 4.1 installation. What the [beeeeep]  is going on? it should be getting in the second part of the installation script where it will set vSwitches settings e.g.. The problem was in the part of the script where the script choose the first discovered disk to install onto we had used this command:

autopart –firstdisk –overwritevmfs

But with a HP Proliant blade (BL 460c G6) this will not work unless you uses the command like this :

autopart –firstdisk=hpsa,cciss,local –overwritevmfs

the hpsa is for SA P410i BL460C G6 the cciss is for SA E200i BL460C G1 and local is for the OTA servers.

!!!!! Warning !!!!!

When using this option un-present all LUN of the responding Host before installation or else you will end up with an new installation of ESXI on your First available LUN

Microsoft OCS on Linux

Daniel de ZoeteComments Off on Microsoft OCS on Linux

As one of the few, i use a Linux environment on my  laptop for production. Now that we use Microsoft Office Communication Server, I needed to find a way of connecting to Microsoft OSC from my laptop. Luckily more people had this same challenge and so a project was started on sourceforge.net for the development of a plugin for pidgin. This plugin “SIPe” (http://sipe.sourceforge.net/) enables you to communicate with Microsoft OCS.

When creating a virtual machine from a template in VMware Vsphere, most of you will make use of the “Guest Customization Wizard” to create a new SID for Windows Virtual Machines and other sort of things in which you want your new virtual machine to differ from the template.

Normally this is no problem, but when you want the newest of the newest like Microsoft Windows Server 2008 R2 64-bit, VMware doesn’t support guest customization, not even when you have updated your ESX and Virtual Center to the latest software-level. You get the following message:
