Upgrade: VCSA 6.0 Embedded PSC to 6.0 U1

Written by Suhas Savkoor

Previously we saw how to perform a fresh installation of Embedded appliance 6.0

This article discusses how to upgrade your existing 6.0 vCenter Server Appliance to 6.0 U1 hosted on an embedded PSC. With 6.0 GA we do not have the VAMI page for VCSA management, so the upgrade should now be performed through the command line of the appliance.

Step 1:
Download the vCenter 6.0 U1 appliance from this link here
The second option is the appliance ISO

Download this ISO and attach it to the existing 6.0 appliance virtual machine.

Step 2:
  • Before proceeding with the upgrade, take a snapshot of your existing 6.0 appliance, so that we will have a restore point to revert to in case something goes wrong.
  • Since this is an embedded PSC install, take a SSH (Putty) session to the appliance which has the Update 1 ISO already mounted. 
  • Login with root credentials that was setup during the install. 

Choice 1:
To apply the patches immediately, run the below command:
software-packages install --iso --acceptEulas

Reboot the appliance and the upgrade is completed successfully.

Choice 2:
You can stage patches and do the upgrade later at a convenient time as well. This works in three steps:
  • Stage the patches to the appliance
  • Review the staged patches
  • Apply the staged patches to appliance
To stage patches, run the following command:
software-packages stage --iso --acceptEulas

To Review staged patches, run the below command:
software-packages list --staged

To apply the staged patches, run the below command:
software-packages install --staged

Once the upgrade is done, reboot the appliance.
Now, this being a 6.0 update 1, we have our management web GUI back. So after the upgrade, go to: https://<vcenter_ip_or_fqdn>:5480

Login with root credentials to verify everything is running fine.
You can also see that from here onward, you can perform the patching and update from the GUI of the appliance.

That's all there is to it!
