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 […]

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 […]

Site Recovery Manager (SRM) 5.8.1 Unable to Export Recovery Plan History

January 10, 2017 Bilal Ahmed 0

Basically, I had a recovery plan and I had done tests/cleanups/migrations/re-protects and it all worked exactly as expected,. But each time when I wanted to export the history reports it wouldn’t do anything! I would pick the type of report I wanted (html/doc etc), I would click generate report. It would generate it fine. But when I clicked download…I would get nothing. I click it and click it and nothing would happen?! I tried Chrome and Firefox, I had rebooted the SRM  service at both sites, the Web Client service at both sites. I had tried a different user account, I simply could not get the report to export. But every other plan exported fine. Then I was asking in the […]

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 […]
