Yesterday and today my colleague Rob Mokkink and I were getting very negative feelings towards the VizionCore vRanger Pro and Veeam Backup products, but like often, the problem existed behind the keyboard. But we prefer to call it an “undescribed feature” of these products.
We downloaded the latest versions of both products to see which product would fit best in our current environment and connecting to the Virtual Center servers went flawless but with neither of the 2 products we could connect to our ESX hosts. Errors that occured were errors that nobody experienced before, according to the product support forums. Read the rest of this entry »
One of the things you have to be carefull within a Virtual Infrastructure environment, just as in every other environment by the way, is how your LUNs are balanced over the HBA’s. Especially when you have a pretty dynamic infrastructure you might not always pay attention to this.
My colleague Rob Mokkink has made a pretty nice powershell script that balances LUN’s on the different HBA’s.
On one of my previous articles Sven, who is actually a colleque of mine, asked if it would be possible to remove snapshots which were left unaccounted for. I reacted is a simple way: yeah, of course and as a matter of fact is is very easy. I really must say the guys from the VI Toolkit have done a great job on maki Read the rest of this entry »
In the light of the offically released Virtual Infrastructure Toolkit I decided to create a simple powershell script. I’m planning to create more powershell scripts and post them on virtualfuture.info.
The first one is a script which can remove the connected iso files from the CD drive. Some administrators do not disconnect a CD drive when the have finished use the ISO, the side effects of this behaviour are: the VM regurally polls the CD drive which creates a slight overhead and a VMotion may fail. This script can run unattended e.g. every night so even when an ISO file remains mounted it is ejected everynight. Read the rest of this entry »
People who want to have scripting abilities added to their ESX farm can now finally download the Powershell addon for VMware Infrastructure because is has been officially released and thus supported. This addon is far more easy to learn than visual basic or perl scripting (the previous scripting languages you had to learn if you wanted this kind automation). The VI Toolkit added over 120 commandlets which eases the automation and scriptablity of ESX servers or an ESX farm.
