VCENTER SERVER

Most vSphere admins are more than comfortable with using Update Manager to download patches and update their environment, but few that I talk to actually know a huge amount about the Update Mangaer Download Service (UMDS). UMDS is tool you can install to download patches (and third party VIBs - I'll get to that) for Update Manager and it's useful for environments that don't have access to the internet, or air-gapped, and also for environments with multiple vCenter Servers where you don't necessarily want to download the same patch on every server.

As a vExpert, I am blessed to get 1000 CPU hours access to Ravello's awesome platform and recently I've been playing with the AutoLab deployments tailored for Ravello. If you're unfamiliar with Ravello's offering(where have you been?!) then it's basically a custom hypervisor (HVX) running on either AWS or Google Cloud that allows you to run nested environments on those platforms. I did say it's awesome. As an avid home-lab enthusiast Ravello initially felt weird, but having used it for a while I can definitely see the potential to augment, and in some cases completely replace the home lab.

Note: This falls under the “I don’t think this is supported” category – use this method at your own peril! As part of some testing I’ve been doing for vRealize Automation DR scenarios, I wanted to test changing the IP address of a HA PSC pair using a script (think SRM failover to a new subnet).What I didn’t want to do was simply edit the connections directly – quite often with the VMware appliances there are scripts on start-up to ensure the configuration is correct and consistent – what I wanted was to be able to find a more supported and reliable way.

I'm not sure how supported this is, but this process can recover a vSphere 6 vCenter Server Appliance or Platform Services Controller when you've lost the root password. Download the OpenSUSE Rescue CD - http://download.opensuse.org/distribution/13.2/iso/ Mount the CD to the PSC Appliance   Reboot the appliance and enter the BIOS setup using F2, configure the CD-ROM as first-boot device. Save and exit to reboot into the SUSE Live-CD.

Providing a highly available single sign on for vRealize Automation is a fundamental part of ensuring the availability of the platform. Traditionally, (vCAC) vRA uses the Identity Appliance and relies on vSphere HA to provide the availability of the SSO platform, but in a fully distributed HA environment that's not really good enough. It's also possible to use the vSphere 5.5 SSO install in a HA configuration - however, many companies are making the move to the latest version of vSphere and don't necessarily want to maintain a 5.

After deploying a new vSphere 6 vCenter Server Appliance (VCSA) and configuring the Platform Services Controller (PSC) to act as a subordinate Certificate Authority (CS), I was unable to register the NSX Manager to the Lookup Service. Try saying that fast after a pint or two!? Attempting to register NSX to the Lookup Service would result in the following error: NSX Management Service operation failed.( Initialization of Admin Registration Service Provider failed.

I tested vSphere 6 quite intensively when it was in beta, but I didn’t ever upgrade my lab – basically because I need a stable environment to work on and I wasn’t sure that I could maintain that with the beta. Now 6 has been GA a while and I have a little bit of time, I have begun the lab upgrade process. You can see a bit more about my lab hardware over on my lab page.

I will be upgrading vCenter Server Appliance - currently 5.5 update 1 vSphere Update Manager - currently 5.5 update 1 3 HP N54L resource hosts 1 Intel NUC management host In my lab I run various VMware software suites listed below, although I typically run them in nested environments to keep my lab install relatively clean.

Checking for driver compatibility In vSphere 5.5, VMware dropped the drivers for quite a few consumer grade NICs - in 6 they've gone a step further and actually blocked quite a few of these using a VIB package.

Upgrading the vCenter Server Appliance Download and mount the VMware-VCSA-all-6.0.0-2562643 ISO image (mounted as G:\ on my workstation). Browse the ISO and run the Client Integration Plugin “G:\vcsa\VMware-ClientIntegrationPlugin-6.0.0.exe” - it's a simple next, next finish sort of install.
