Moving from vSphere 5.5 to vSphere 6.5 Part 2 #Upgrade #Migration #Fresh #vExpert #vSphere #VCSA

January 15, 2019 Bilal Ahmed 0

So now we have got all the back story out of the way with Part 1, we can get into the meat of it all. The Middle I used various scripts, from various places and used the web client to get everything how I needed it to be. These scripts are provided AS IS, use them at your own risk, they worked for me. I have credited everyone I borrowed the source scripts from, and even provided the location of the source scripts too. A lot of people put effort into making the scripts, so I thought it would only be fair people knew where they came from. I made edits and adjusted as I needed to get the job […]

Moving from vSphere 5.5 to vSphere 6.5 Part 1 #Upgrade #Migration #Fresh #vExpert #vSphere #VCSA

January 15, 2019 Bilal Ahmed 0

So I have been meaning to write a post on this for a while, so I thought I better get started! So let me tell you a story! The Beginning Now as we all know vSphere 5.5 went EOL a little while ago. So in preparation, I was investigating the various options that were available for the business, to keep them supported. When I first joined the business years ago. it was all a vSphere 5.1 environment that didn’t get patched often and hosts had very very long uptimes. the reason I was brought on board was to get a handle on this and bring it all into line. One of the first jobs was to actually re-ip the whole environment […]

Very persistent NTP issues on VCSA and PSC appliances

May 11, 2017 Kim Bottu 3

For the 2 weeks I had been having very annoying NTP sync issues on some of my VCSA and PSC appliances in one of the datacenters. While my SSO domain and vCenter enhanced linked mode were for the most part working properly, it still bugged me that the NTP clocks on my PSC and VCSA in datacenter 1 were properly syncing with the NTP source (windows NTP source), but the NTP time on my PSC and VCSA in datacenter 2 were always off with somewhere between 3 to 7 minutes with the clocks of all my other appliances and Windows VM’s. They did how ever sync properly with each other. (For trouble shooting purposes, I pointed all appliances to a single NTP source in a single […]

Emad Younis & Adam Eckerle – The vCenter server and Platform Services Controller Guide to the Galaxy

October 18, 2016 Kim Bottu 0

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 […]

Adding a second NIC to a VCSA

April 24, 2016 Graeme Vermeulen 0

Here’s how you add an additional NIC on a VCSA – and I’ll show you step-by-step with actual keyboard commands as no other guides out there do: The VAMI can be accessed via https://(IP or FQDN):5480 – the username is normally root and the default password is vmware Typically this is what you’d see on most standard instances: Adding the additional NIC in vSphere in as easy to do as you’d expect: But you won’t see the additional NIC in the VAMI: It will actually start throwing errors. We need to set add the new NIC manually. To do this, you can either use CLI or YaST2. YaST2 is a SUSE management tool which lets you configure basic elements of […]

Can’t login using Windows Session Credentials – VCSA (vSphere 6)

April 24, 2016 Graeme Vermeulen 0

Quite a few things seem to have changed with the VCSA in vSphere 6. The most obvious change is that the appliance is no longer deployed as an OVA / OVF template but rather from an ISO image. As part of deploying the ISO, you’ll be prompted to put in your settings for the vCenter before it’s even powered on. This can be quite tricky to get right the first time – so make sure you have created the relevant DNS records on your DNS servers and configured your VM network on the chosen host for initial deployment. Setting up SSO for your Windows Domain is exactly the same, however when ticking the “Use Windows Session Credentials” box you will […]

Windows vCenter vs. vCenter Server (Virtual) Appliance (vCSA/vCVA)

March 22, 2015 Shady ElMalatawey 5

The following question about vCenter Server is which version to deploy: Windows vCenter Server or vCenter Server Appliance (vCSA). First, let’s examine the components of any vCenter Server. They’re Single-Sign On (SSO), Inventory Service, vCenter Server, Web Client and a back-end Database. To answer the question above, we need to take a deep look at how answer of the above question affects all of these components. Keep in mind that it’s also related to the way you’d deploy your vCenter Server Components according to your customer/case needs and requirements or constraints. Some components and other VMware products deployment are affected by wither you’d use Windows vCenter or vCenter Server Appliance (vCSA). My vExpert colleague, Mohammed Raffic, made a great comparison between […]

Virutalizing vCenter Server: Yes or No?

March 13, 2015 Shady ElMalatawey 1

“Should I virtualize vCenter Server or not?!”.. This question is asked a lot, specially during preparing for new vSphere deployments. IMO, and in 99.9% of all cases I meet, I answer with “Yes!! Why not?”. vCenter Server is a central part of your Management Layer of your infrastructure that requires high level of availability and performance. vSphere 5.x is capable of providing the required level of performance for vCenter Server itself or for any one of its components (SSO, Inventory Service or Web Client) as well as its required back-end Database. In the same time, virtualizing vCenter Server provides higher level of availability, using vSphere HA and the new SMP Fault Tolerance in vSphere 6.0. Despite many advantages of virtualizing vCenter Server, […]
