Updating ESXi host & vCenter Server

Different methods are available for upgrading ESXi host as listed here.
I have used the very common methods to update i.e

1. Directly connecting the iso on the server and upgrading

2. Online upgrade from VMware software repository




Updating ESXi by mounting ISO

• Before upgrading ESXi 6.0.0 Build 2494585
  
  

• Inserted the CD/DVD.

           

   

• Initialised the server to install ESXi then choosen the option Upgrade ESXi, preserve VMFS Datastore.

         

• Once upgrade is done, just have to reboot the ESXi and here you go, ESXi has been successfully upgraded to the appropriate version.

Online update of ESXi by connecting to the repository

• You can click here for latest patch release of ESXi 

• Before running this command you just have to make sure your ESXi has http client is enabled 

The same could be done using ESXi by configuring the firewall using ESXCLI:-
To Enable the rule:-
esxcli network firewall ruleset set -e true -r httpClient

To disable the rule:-
esxcli network firewall ruleset set -e false -r httpClient

Finally you have the ESXCLI with which it could be upgraded. 
It will take significant amout of time depending on your bandwidth.

esxcli software profile update -p ESXi-6.0.0-20160804001-standard \ 
-d https://hostupdate.vmware.com/software/VUM/PRODUCTION/main/vmw-depot-index.xml

Once everything is done, just reboot and enjoy.!!
