Once we’ve installed RHEVM and our RHEV-H’s how should I upgrade the hypervisors?
In order to do so, on the RHEVM machine, we need to install the isos images of RHEV-H:
yum install rhev-hypervisor6.noarch
NOTICE: If you’re unable to install this package add the following channel:
rhn-channel --add -c rhel-x86_64-server-6-rhevh
And we’ll notice that /usr/share/rhev-hypervisor/ contains the iso images of RHEV-H:
ls /usr/share/rhev-hypervisor/
rhev-hypervisor.iso
rhevh-6.2-20120209.0.el6_2.iso
version-6.2-20120209.0.el6_2.txt
rhev-hypervisor6.iso
rhevh-latest-6.iso
version.txt
Once it’s installed, we can put our RHEV-H into maintenance mode, and will see this option:
-
Host is in maintenance mode, you can Activate it by pressing the Activate button. If you wish to upgrade or reinstall it click here.
- rhevh-latest-6.iso
And that would be it, let RHEVM install the upgrade and the node would be automatically rebooted with the newer version of RHEV-H.
