Update Manager

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. You can control which patches you download (for example, limiting to ESXi 6.7+ only) and you can add third party Vendor repositories (e.g. Dell or HPE).

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.

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. For more information, see this excellent article by Andreas Peetz.

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.

I’m currently updating a very small 4-host cluster built for a specific application within our datacentre, the hosts are IBM HS22 blades. Since we have the VMware Update Manager infrastructure in place already, I downloaded the IBM ESXi 5.0 Update 2 ISO and imported it into Update Manager, created a baseline and then applied it to the cluster. I scanned the cluster with the baseline and was issued this warning for each host:
