vBrownbag Session – Upgrading from vSphere 5.5 to 6.x

VMworld 2018, I was lucky enough to get my name down on the list to present on the vBrownbag stage, a community driven source of brilliant knowledge articles, videos, and web meetings, for the community by the community. Read more about vBrownbag here

In the below session I took on the session that had proved to be a hit at VMUGs around the UK. “Upgrading from vSphere 5.5 to 6.x”

This session focuses less on the “how to upgrade the components themselves” but more what you need to cover for planning and preparation, considerations during the upgrades, and calling out known gotchas.

Since the above video, I’ve since joined VMware, and presented the official slide deck covering this subject at the UK VMUG Usercon with Kev Johnson, Technical Marketing Engineer – vSphere Lifecycle.

You can find the official free e-book that accompanies the VMware presentations here;

Upgrading VMware vSphere 5.5 to vSphere 6.5 (VMUG Presentation)

Blog post born from a VMUG Presentation

Mid Feb, one of the London VMUG leaders posted on twitter, looking for someone to present on the subject of “upgrading from vSphere 5.5 to vSphere 6.5”.

So I jumped at the chance, kind of, and offered to present. This blog post covers the content from that presentation.

  • vSphere 5.5 – End of Support
  • vSphere 6.5 – New features
  • OK, so let’s just upgrade then?
  • The plugin’s
  • SSO is gone!
  • Understand your topologies
  • Pre-Upgrade Tasks
  • The Upgrade, the big event
  • Gotcha’s
  • VSAN Considerations
  • vShield Manager is no more! Upgrade to NSX Manager
  • Resources

The presentation is available to download here – http://vexpert.me/London-vmug-dean (case sensitive link)

Or I’ve figured out how to embed it from Slideshare.net below (But animations don’t seem to work);

vSphere 5.5 – End of Support
  • End of General Support for vSphere 5.5 is September 19, 2018
    • Includes vCenter 5.5, ESXi 5.5, VSAN 5.5
    • KB 51491
  • In the event you are unable to upgrade before the End of General Support (EOGS) and are active on Support and Subscription, you have the option to purchase extended support in one year increments for up to two years beyond the EOGS date.
    • Expect this to be more costly than general support.
    • SLA’s are more akin to that of basic support rather than production support
    • Annual security patch. Includes catastrophic/critical security fixes only
    • Ability to create hot patches for Severity 1 issues only
  • Technical Guidance for vSphere 5.5 is available until September 19, 2020 primarily through the self-help portal.
  • During the Technical Guidance phase, VMware does not offer new hardware support, server/client/guest OS updates, new security patches or bug fixes unless otherwise noted.
    • For example, there was no SPECTRE/Meltdown security patches released for vSphere 5.1

It’s not only the core vSphere 5.5 products that are affected, as we can see from the End-of-Support tracking page provided by virten.net. There are other VMware solutions that you have deployed that may also need upgrading.

VMware Update Manager

Using VMware Update Manager to automatically download Dell Drivers to ESXi

Last year I wrote about how to use VMware Update Manager to download HP Drivers for ESXi,

Since then I’ve also found out you can add the following Dell repository into VMware Update manager;

Upgrade VCSA to VMware vCenter 6

So I jumped right in and upgraded my VCSA 5.5 to VCSA 6, you can find the official documentation and upgrade steps here.

Pre-Reqs from VMware

  •  Verify that the clocks of all machines on the vSphere network are synchronized. See Synchronizing Clocks on the vSphere Network.
  • Verify that the ESXi host on which you deploy the vCenter Server Appliance is not in lockdown or maintenance mode.
  • Verify that the vCenter Server SSL certificate for your existing vCenter Server Appliance is configured correctly. See VMware Knowledge Base article 2057223.
  • If you use an external database, back up the vCenter Server Appliance database.
  • Create a snapshot of the vCenter Server Appliance.

What you need before you start

HP-AMS Driver causes ESXi memory leak

So basically I had a customer hit by a known HP-AMS driver issue (KB2085618), the symptons were as follows;

  • Unable to vMotion a VM to another host, gives “operation timed out error”

2014-11-10_10-36-15

  • If power off VM, vMotion a machine to another host, and then power on, you get the following error “Could not start VMX: msg.vmk.status.VMK_NO_MEMORY”

2014-11-06_10-42-49

ESXi memory leak

This issue is caused by a memory leak in the driver which fills the SWAP memory of the ESXi host, making it unable to response to any requests at all,

For example, trying to enable SSH;
