Step 20:  Upgrade the ESXi hosts using Update Manager

20.1: The first step to carry out is to create a new baseline with the ESXi image. To do this go to Update Manager from the home page on the vSphere client

20.2: Click on the ESXi Images tab as you’ll need to upload the image before configuring a new baseline. Select Import ESXi image

20.10: Next click on Scan and select Upgrades as the scan criteria. Click Scan

20.11: This will kick off a scan across the entire environment.  As there are two different sites with separate Update Manager Servers the above steps will need to be carried out there also.

20.12: The next steps are to update the individual ESXi hosts to not cause any downtime. Put one of the hosts in maintenance mode and migrate any VMs from it. The host will need a reboot following the upgrade. Once the selected host is in maintenance mode select Update Manager

20.13: If you see an error about ‘host software configuration requires a reboot’. Follow the instructions and reboot the host. – http://kb.vmware.com/selfservice/microsites/search.do?language=en_US&cmd=displayKC&externalId=2034945

20.14: Once the host is rebooted re-run the Update Manager scan. Compliance will now show Non-complaint rather than Incompatible.

20.15: Next click on Stage to push the software out to the host. This will just speed up the upgrade process. Once the staging has been completed then click on Remediate to complete the upgrade process

2015-04-08_13h18_25

20.16: Once the Host Upgrade is selected click Next during the remediate process

20.17: Accept the EULA and click Next

2015-04-08_13h20_57

20.18: Select remove incompatible third-party software if needed. Double-check what VIBs are installed on your hosts before upgrading. Click Next.

2015-04-08_13h21_10

20.19: Set the task to run immediately and click next

2015-04-08_13h22_38

20.20: Leave the defaults and click Next

2015-04-08_13h23_25

20.21: Choose what options you’d like to use as part of the upgrade and click Next

2015-04-08_13h24_05

20.22: Click Finish to complete the task

2015-04-08_13h24_25

20.23: A new remediation task will begin.

2015-04-08_13h24_58 2015-04-08_13h27_43 2015-04-08_14h02_42

20.24: Keep an eye on the remediation in case there are any alerts that appear. Once the remediation has completed Update Manager will show the host as being compliant.

2015-04-08_14h03_46

20.25: Exit maintenance mode and migrate some VMs back onto the host. Follow the same above steps on all the remaining ESXi hosts.

 

Step 21: Upgrade DVSwitch versions

21.1: Once the ESXi hosts have been upgraded you can then upgrade any dvSwitches. Go to Networking and select the dvSwitch. Check the version number. If it’s a previous version to the current version of vCenter it will ask for an upgrade. The ESXi hosts need to be upgraded first so now is the time to upgrade the dvSwitches.

2015-04-08_23h08_45

 

21.2: Select upgrade and select vSphere Distributed Switch Version: 5.5.0. Click Next to continue.

2015-04-08_23h08_54

21.3: The hosts are checked for compatiblity. Once they get the all clear click on Next.

21.4: And that’s it. The version of you distributed switch has been upgraded

 

Step 22: Upgrade VMware tools

22.1: You can view the VM Version and tools status from the top cluster view. If the tools are out-of-date they will need to be updated.

2015-04-08_16h38_15

22.2: Open a console session  and select VM-> Guest -> Install/Upgrade VMware Tools.

2015-04-08_16h36_59

22.3: You can select Automatic mode if you want to quickly update, however I need to ensure that the vShield agent is installed so I’ve selected Interactive Mode and clicked Ok

2015-04-08_16h41_28

22.4: Select Run setup when prompted

2015-04-08_16h42_26

22.5: The installation will then begin. Click Next on the first dialog

2015-04-08_16h43_35

22.6: Select Custom and click Next

2015-04-08_16h44_23
22.7: Click Next and then click Finish to complete the install. You may be asked to reboot the server, most likely you will have to.

Congratulations!! You’ve now completed all steps of the upgrade. You can choose to upgrade the hardware version of the VMs as well. In my case it was decided due to the nature of some of the VMs the benefits they would get from the hardware upgrade it was decided to leave that upgrade component until a later date.
