So this has been an ongoing saga for quite a while: Repeated VDDK error 1 and 2 This is an issue I blogged about a little while ago too, right here: WARNING: Veeam Backup VDDK error 1 and 2 ESXi 5.5/6 Veeam B&R v8/9 It has been causing people plenty of issues and although it’s simple to fix, it’s annoying and it shouldn’t be happening! Veeam and VMware have been pointing the finger at each other for months now. Personally I would lean to it being a VMware issue, simply because a restart of the management agents resolves the issue. So I have been following the thread on the Veeam forums and there has finally been an update! VMware have […]
We are delighted to announce that Manny Sidhu is joining vMusketeers! Manny currently works from Melbourne Australia, has been a vEXPERT for the last 3 years and has been announced as a vEXPERT NSX for 2016. Like the rest of us he is a huge fan of VMware , virtualization and a certification junkie. Thanks for joining our merry band of vMusketeers Manny!
These are the steps I took to apply this fix: First thing I did is I took a Veeam backup of the VM, then I copied over the files as downloaded from: Additional patch for security issue CVE-2015-2342 for vCenter Server 5.x on Windows (2144428) I did a md5 check Opened Command Prompt as administrator, and navigated to the folder where I had extracted the script and ran: cscript JMXScript5.<x>.vbs “<location_of_wrapper.conf_file>” cscript JMXScript5.5.vbs “C:\Program Files\VMware\Infrastructure\vShereWebClient\server\bin\service\conf\wrapper.conf” Since I was running 5.5u3b, I already had a partial fix so it was just a matter of running the script to fully patch it. The script stops the web service, does it business and restarts the web service again. This takes about a minute or so. The […]
Configuring the alarms isn’t all that easy and not documented that well. In the vExpert slack I was chatting to @railroadmanuk Tim as he was trying to configure up some alarms, and this is something I have been meaning to dig into more myself. He started me off in the right direction telling me he configures them from the vCenter server alerts. So, vCenter Server > Manage > Alarm Definitions and from here you create a new alarm. I needed to create an alarm for when a new VM is put onto a replicated datastore and an alarm when a currently protected VM has been configured in a way, which would impact its protection status (eg new VMDK on a non replicated datastore […]
The CPU over-commitment ratio also known as the vCPU to pCPU ratio. In this post I will test this new feature of vSphere 6.5 and how it impacts a vSphere 6.5 datacenter design. I am testing this because some of the information about this setting is kind of vague and I want to be sure that I understand how it works and what its impact is on production environments and how it will affect vSphere designs. To be able to test the above mentioned features I have setup a small test environment using 2 nested ESXi hosts, a nested VCSA 6.5 server and a handful of VM’s. The Cluster: 2 hosts HA is disabled DRS is enabled ( because this is a DRS feature!) The hosts: Both hosts have the […]
Colocation is awesome. For those of you that don’t know what it is exactly, let me explain it quickly. Colocation means running your company-owned hardware off-premise, usually in a datacentre. You rent space in the datacentre in the form of racks or “rack units” which is encapsulated in a monthly fee. Why choose colocation? Convenience – No matter how big your company is, running servers and hardware on-premise is expensive. You’ll need a dedicated room which should have – actually NEEDS – reliable power supply, air-conditioning and redundant internet links coming in from the outside world. Not to mention the room needs to be physically secure to prevent hackers from being able to physically access or steal the hardware, and […]
If you have questions about the deployment of or migration to the VCSA no matter what version, Emad and Adam are probably the guys you want to have a conversation with and the session called ‘The vCenter server and Platform Services Controller Guide to the Galaxy’ should be the first session you should check out at VMworld Barcelona. The right question to ask yourself here is: why would you want to stay with the Windows Server hosted vCenter server? Because you are used to it and everyone in your department can support it? Because the database administrators know perfectly well how to support Oracle or MSSQL databases but no Postgres? Because the Windows vCenter server historically has supported more features and has […]
This presentation was actually co-hosted by Guido Appenzeller, the CTO for the NSBU and Scott Lowe who hardly needs any introduction anymore. In this session they elaborated further on how NSX will bridge clouds together and gave live demonstrations on how it all works! Note: I scheduled this session without actually knowing what to expect. Often these kind of sessions tend to be loaded with marketing talk which doesn’t interest me in the least. However this session in reality was a true gem. The guiding principles The guiding principles for a multi cloud network are that software really has to be independent from the hardware, the software had to evolve to a new model and some form of cloud networking is needed of course. Let’s […]
