Resizing VMDKs with vSphere Replication #vExpert #vSphereReplication

December 12, 2017 Bilal Ahmed 0

*picture from VMware docs Now then, everyone that has used VR knows that resizing VMDKs for replicated VMs isn’t the easiest thing to do. But I have come across people who seem to believe that the only way to resize the VMDKs is via the CLI on a host….this is one of the options BUT IS NOT the only one. Resizing via the CLI: https://kb.vmware.com/s/article/2052883 > No need for me to repeat what it says, but you do it using vmkfstools. It works well but does require the person to have access to the host directly. The key point when using vmkfstools , which isn’t totally clear in the kb is: If the original size was 550GB and the new […]

Lets Talk About Sexigraf @Sexigraf_fr #Sexigraf #Monitoring #vExpert

October 9, 2017 Bilal Ahmed 0

So I went to my first VMUG recently and it was great! I met plenty of new people and learned a lot of new things. I got in a few discussions about monitoring and I mentioned that I was pretty fond of Sexigraf @Sexigraf_fr . I found it interesting that a few people had never heard of this great FREE product. I mean monitoring is important, whether you want to know what your cluster utilisation is or how your datastore latency is or how your VSAN cluster is doing. Keeping stats for a period of time is also important because you want to be able to monitor trends etc. There are plenty of products out there that can help you […]

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 […]
