We are launching the restarting of the concerned vCenter servers.
Update(s):
Date: 2012-03-28 16:16:23 UTC Tonight, we are going starting a new maintenance on other vCenters.
A 15 minutes cut of the vCenter is expected from midnight.
Date: 2012-02-29 03:03:36 UTC vCenters are up.
Maintenances for tonight are completed.
Date: 2012-02-29 03:02:53 UTC Following a maintenance on another set of vCenters.
We are expecting a cut-off for about 15 minutes.
Date: 2012-02-24 09:55:36 UTC We perform the same maintenance on other vCenters that have the same problem.
This will create an interruption of 15 minutes.
Date: 2012-02-21 03:15:46 UTC The service is up.
Date: 2012-02-21 03:15:23 UTC The second phase can not be done quickly, we will suspend the vCenter service for a few minutes.
Date: 2012-02-21 03:12:28 UTC The first stage of maintenance is complete.
We check the correct working.
Tonight at midnight, we will begin the second stage, that will not cause cutting the vCenter service.
Date: 2012-02-21 03:09:44 UTC In order to fix these problems, we will perform a maintenance on these vCenters.
The service will be interrupted for 15 minutes.
Date: 2012-02-21 03:08:49 UTC Some vCenters remain unstable.
Sometimes we have false alarms about the status of Hosts as seen by the vCenter (showing a red warning in the inventory), while the hosts are functional and therefore the VMs.
We work to remove these warnings, but some warnings remain.
