Hello, I have looked around I think I know the answer but wanted to get clarification that I am on the right path.
I need to update 4 ESX host that are on a seperate non connected to the internet network. We are running Vsphere 4.
From what I read I can not use the update manager in Vsphere because we are not direct connected to the internet.
Since I do not have a Vsphere setup on the web with update manager I can not download patches and then move them over into a shared repository.
What I can do is download the patches manually, the .zip file. Place the update on a sFTP server. Log into the ESX host I want to update, use a get command to move the patch to the server. run ESXUpdate to install.
Basically thinking of the following steps, log into the Host.
esxupdate query - to show me the updates that have been applied.
Downloaded the patch / patches from the VMware Patch website
Place .zip patch on the sFTP server
Connect to the server using Putty
Make a directory with mkdir /var/updates and chmod 777 on /var/updates
Used get command to copy the patches to my ESX Server
After changing into the /var/updates folder, I Unzip the patch with unzip ESX400-200906001.zip
I then changed directory into that folder with cd ESX400-200906001
Then installed the patch with esxupdate update
The host will be in maintenace mode when this is being done.
Any help or suggestions appriciated.
