WARNING: Veeam Backup VDDK error 1 and 2 ESXi 5.5/6 Veeam B&R v8/9 Updated: 03/01/2017

January 3, 2017 Bilal Ahmed 0

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 […]

Upgrading vSphere Web Client due to Fix Security Issue CVE-2015-2342 5.5u3b

December 13, 2016 Bilal Ahmed 0

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/Creating Custom Site Recovery Manager 5.8.1 (SRM) Alarms

December 6, 2016 Bilal Ahmed 0

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 Host Virtual MAC Address Riddle

September 5, 2016 Bilal Ahmed 0

For ages I have been pondering over ‘something’ which seems very trivial and the fact I can’t get any solid info on it is driving me nuts: Why does every pNIC also have a virtual MAC address? So here with have the VMkernel ports, a VSS and pNICS: Just as you would expect, every physical NIC (pNIC) on a host has a MAC address. BUT when you type ‘esxcfg-info -n‘ in the shell, you will notice that every vmnic also has a Virtual MAC Address!   \==+Physical Nic : |—-Name…………………………………………..vmnic3 |—-PCI Segment…………………………………….0 |—-PCI Bus………………………………………..2 |—-PCI Slot……………………………………….0 |—-PCI function……………………………………1 |—-MAC Address…………………………………….XX:XX:XX:32:06:1f |—-Virtual MAC Address……………………………..00:50:56:52:06:1f |—-FPT Shareable………………………………..true Now as you can see the Virtual MAC Address starts off with a VMware MAC and then finishes at the […]

VCAP6-DCV Deployment Beta

July 18, 2016 Bilal Ahmed 0

So myself and Kim did this exam the other day. Kim hasn’t done any DCA style exam before, and he had a similar experience to me on my first go. It kind of hits you like a train and its a lot to take in initially. The beta signup period didn’t give anyone much time to actually prep for it properly. Having done the 5.5 DCA, I remember looking at  some of the questions and wondering what they were wanting……exactly. I did what I thought was correct, you don’t have time to second guess yourself, you just get on with it and do what you can. The best explanation for the DCA/Deployment exam is: Imagine you are a contractor and […]

WARNING: Veeam Backup VDDK error 1 and 2 ESXi 5.5/6 Veeam B&R v8/9

June 7, 2016 Bilal Ahmed 2

Also read the follow up post: VeeAM Backup VDDK error Follow-up and solution So recently I came across a strange problem. Random VMs from various different jobs, would fail to back up, I would get a VDDK error. Now the last time I had this error, was when I had just joined a company and it turned out to be a faulty disk on a local host that had failed,  and it had been in a failed state for so long that the whole vdisk on the Dell host was compromised and I had a punctured RAID. There was no monitoring in place! rest assured that’s sorted now. But these were all SAN based, on different datastores and on different SANs. […]

Book Review: Networking for VMware Administrators

May 26, 2016 Bilal Ahmed 0

So I have been collecting lots of books ever since I started on my journey of doing my VCAPs. One book time and again has been my go to reference for absolutely anything VMware networking related….and you guessed it…IT’S THIS BOOK! When I have been in chats with networking guys, and we have been discussing various features, I can point them to sections of the book, and if I need to confirm something I can double check it quickly. You do not need to be a networking guru to use this book. I have/had a CCNA (it has expired), so I have a fair idea, but I am by no means a networking guru and I have learnt plenty from […]

Book Review: VMware vSphere Troubleshooting PACKT Publishing

May 26, 2016 Bilal Ahmed 0

I am a big fan of PACKT Publishing books, I have quite a few. So I thought I would start writing reviews on them. I just bought this one, one thing I like is that you get the pdf instantly and the physical copy comes in about 5 days. So I can access it instantly while waiting for my physical copy to turn up. I have read through most of it, it is split up into the following chapters: The Methodology of Problem Solving Monitoring and Troubleshooting Host and VM Performance Troubleshooting Clusters Monitoring and Troubleshooting Networking Monitoring and Troubleshooting Storage Advanced Troubleshooting of vCenter Server and vSphere Hosts Appendix A: Learning PowerGUI Basics Appendix B: Installing VMware vRealize Operations […]
