VCDX #251 at your service with a smile!

June 18, 2017 Bilal Ahmed 0

So I recently managed to get my VCDX number! waheyyyyyyyyyyyyyyyyyyyyyyyyyyy It was a long process for me, which I am now going to break down. Hopefully this will give people some insight into how everything comes together and I do hope it will give future candidates an idea of how to approach it. The Start So back in early 2016 I knew someone who was considering pursuing the VCDX, and they asked if I wanted to partner up with them. I initially declined…..simply because I didn’t think I had the skill level currently to even consider such a task. Their response was ………..how else are you going to get the skill set? Upon thinking about it, that made perfect sense […]

Bitdefender – True Agentless protection

June 13, 2017 Kim Bottu 0

Last week I was in London at the InfoSecurity convention having a look what is happening in the security world. If you have never attended InfoSecurity, it is a free event where most of the presentations are a bit loaded on the marketing side.  Of course there are always exceptions. The 2-hour workshops are truly gems. At least the workshops which I did attend to. What if you could protect VM’s without agents or without any other piece of installed software? The workshop which really caught my attention was the workshop presented by Andrei IONESCU and Adrian Liviu ARSENE who are both employed by Bitdefender: ‘Data Center Security – HYPERVISOR INTROSPECTION’. Starting with explaining how external and internal threats are evolving they quickly moved on to explain how their […]

How to get some free IT training resources?

June 13, 2017 Kim Bottu 0

IT courses can cost quite a bit of money. If you are like me and want to have more training than your company’s training budget allows you, you might want to have a look at how you can get some free training under your belt. Free training can come from anywhere really, be that ebooks, books, onsite learning platforms or online lab, you just have to look for it and make your pick. Some even come with free certificates of completion. At the bottom you can find my personal  favorite picks. But let me give you some learning possibilities which you probably have not considered yet and let me start with the most unobvious ones: How to become a technical reviewer of a […]

VMworld 2017 Barcelona – Are you going?

June 12, 2017 Kim Bottu 0

A couple of weeks ago I received some very pleasant news in my inbox:  “VMworld Blogger Pass, Barcelona – YOU’RE GOING!” This is the second year VMware bestows this honor on me and I am feeling as happy and honored as I felt last year. Just like last year, I had to read the email a couple of time before I was able to believe the subject of the email. *grin* Of course a free conference ticket only takes you that far. I have to extend my gratitude also to my managers who recognize the value of all the technical sessions at VMworld and who sponsor all my other costs. You guys rock! So what is this VMworld I am writing about? I have always seen VMworld […]

A different take on the SRM upgrade order

March 3, 2017 Kim Bottu 0

Upgrading a vSphere environment with SRM can be tricky. If you follow the official best practice on how to upgrade vSphere and SRM you might find yourself in a position where SRM is out of commission because the last part of the upgrade process,  the part where you upgrade the DR site, fails. The official recommended way to upgrade SRM The official recommended way to upgrade SRM connected sites is to upgrade all components in the Primary sites first and then upgrade the components in the DR site. This means that you upgrade vCenter components followed by the SRM components in Primary Site A first, followed by vCenter components and the SRM components in Primary Site B and then by the vCenter components […]

ERROR vCenter 5.5U2 upgrade to vCenter 6.0U2a: 1603, A change must be made to this systems time and many others

March 3, 2017 Kim Bottu 0

Recently I had several problems upgrading vCenter server 5.5U2 to vCenter server 6.0U2a. Luckily all has been solved now and I owe a huge thank you to  Ciaran McE from VMware Support who has stood by me and helped me to solve this vCenter upgrade problem. Below I am listing a handful of the errors we have seen, how you can spot them and how you can solve them. Error 1: Error 1603. Because SSO appeared to be somehow corrupt [As a test to check if SSO was intact I deleted of a local SSO group resulted in the unavailability of SSO as a whole], I had to install a new external SSO server,  remove and reinstall vCenter server and re-point […]

Site Recovery Manager 5.8.1 SRM and VR Protection Advanced Settings Riddle

February 7, 2017 Bilal Ahmed 0

When you use SRM (in my case SRM version 5.8.1) in combination with VR to protect your VMs, SRM will own these VMs. You will not be able to recover these protected VMs using vSphere Replication on its own, as long as they are SRM protected.  This became an issue for us, simply because we had an issue where the SRM service would fail to start at the DR site. Working with VMware support we got it working again but neither VMware Support or myself really knew what the root cause was. A little SRA and SRM history We are using SRM in combination with SRA’s and had a Recovery Plan that was stuck in partial re-protect mode and no amount […]

vSphere Replication when using vRDMS

January 31, 2017 Bilal Ahmed 0

So you can use vRDMs with vSphere Replication: https://blogs.vmware.com/vsphere/2015/07/vsphere-replication-virtual-rdm.html There aren’t many use cases for it and it isn’t documented very well. So I have just been pondering over something: vSphere replication supports VMs that have vRDMs but not pRDMs. ESXi5.5 now supports vRDMs up to 62TB. What it does, is it will bring the vRDM up as a VMDK file at the DR site. I am throwing this out there as a possible option for replication of our VMs that have RDMs attached, since we have a few VMs that have RDMs attached to them and which need to be replicated too. “If you wish to maintain the use of a virtual RDM at the target location, it is possible to […]
