update hypervisor

Latest response

What are the options to update hypervisor in rhev 3.0?

Suppose a server with mgmt card (es Drac for Dell or iLO for HP), can I attach the iso and boot and proposed a non dsruptive update?

Is there still an approach similar to 2.2 where I put the iso inside a special rhev manager directory?

Thanks

The approach from 2.2 remained in 3.0, on RHEV-M run

 

yum update rhev-hypervisor

and it will be downloaded and placed in the right directory

Thanks Sadique. I didn't remember in which manual I found this information during the beta cycle...

Ok,

I was able to update to latest hypervisor version in less than 6 minutes.

Some points here:

- I'm also testing the technology preview of webadmin portal.

Using it, I was able to put hypervisor in maintenance mode, but after selecting the "install" link and the iso image, I got an error 500.

Making logout/login and reattempting I got no window at all when selectin "install" link.

I see a "javascript;" at status bar on the left.

BTW: browser is firefox 10.0.1 on Fedora 16 and in login windows it appears as not supported, so I don't know if I would get similar problems using RH EL supported os and browser....

 

- After update from admin portal inside ie 8 and windows xp the host comes at final up state this strange things happen:

 

1) in admin portal it appears as UP (as detailed in the manual) but I continue to get

in details pane of the host:

! A new RHEV-Hypervisor version is available

 

while I can see in console of the host and details pane that the kernel is now 2.6.32 - 220.4.2 so it is different than before (2.6.32 - 220.2.1)

 

 

2) in webadmin portal in details pane I get


Host is in maintenance mode, you can Activate it by pressing the Activate button. If you wish to upgrade or reinstall it click

here

.
 
 
While at top there are the correct buttons showing that it is indeed up and not in maintenance, such as:
. activate button is greyed out
. maintenance button is selectable
. status column is "UP" and left icon is representing it
 
 
Both 1) and 2) don't change if I sign out / sign in...
 
 
So repeat step using directly admin portal from windows and I get a new install of the same kernel, but at the end I continue getting the same message about a new version available. And from webadmin portal it continues to say it is in maintenace mode as before...
 
 
BTW: perhaps after update, it would be better to put the host in maintenance mode again and let the admin to manually activate/put up it... just my opinion
 
 
Thanks for support

interesting, do you see that in webadmin, or in the old GUI as well?

1) considerations  --> admin portal 

2) considerations --> webadmin portal

1 is just a mater of time, once the host is UP, this should go away, as it gets rechecked

2 might be a bug, I'll have to try and reproduce it locally. Do you get this every time, or just once?
