Wrong “Uptime” on guests running Windows 2008 / 2008 R2 / 7 / 8

9. July 2015 / / 0 Comments

Today I’ve found a little failure within our production environment.

We use icinga to monitor our production lan, its guests and services. For our Citrix XenApp servers we check the uptime to get notified if they are running to long without reboot.

After we upgrade several servers to vmx-10 everything works fine. Icinga reports all services and performance charts correctly. Now, two days later, the first uptime alerts came up. But the system boot time was only a few hours ago and not two days…

If we power off and power up the machine the uptime does reset.
The counter didn’t reset if the machine is only warm rebooted.

Upgrade vCSA 5.5 to vCSA 6.0 fails with vPostgres firstboot error

1. July 2015 / / 10 Comments

In my previous posts I wrote about the upgrade of vCSA (vCenter Server Appliance) from version 5.5 to 6.0.
In all my lab testing the upgrade runs without any errors. On our production site I was doing the upgrade and the migration went fine until the new appliance boots for the first time.

The services start all until the vPostgres database starts. Something in the upgrade script gives back an error. Installation abort and I must boot the old vCSA 5.5.

VMware closed my call, because of an unsupported way getting vCenter Server for Windows to the vCSA 5.5. Everything runs in the vCSA 5.5. The upgrade fails and with the migrated database there is no support.

Upgrade vCenter Server Appliance 5.5 to 6.0

26. June 2015 / / 0 Comments

As I advertised here is my upgrade how-to for vCSA (vCenter Server Appliance) 5.5 to vCSA 6.0.

In my previous post I show the “workaround” to get a vCS (vCenter Server) 5.5 installed on a Windows Server 2012 R2 on a Windows Server 2008 R2.
After this migration it was possible to “Migrate Windows vCenter Server 5.5 to vCenter Server Appliance 5.5“ with the VMware Fling vCS to vCSA Converter.

Now its time to get the Version of vCSA from 5.5 to 6.0

Migrate Windows vCenter Server 5.5 to vCenter Server Appliance 5.5

24. June 2015 / / 0 Comments

The VMware Labs engineers created a converter machine to migrate your vCenter Server 5.5 installed on a Microsoft Windows Server to the vCenter Server Appliance.

This guide shows the steps to successful migrate the data.

Attention:

With the experience I’ve made I could not recommend the use of the Fling in production. I’ve tested several times the conversion in Testlab without any errors. But the database of our production seems to have many object which are not upgradeable from vCSA 5.5 to vCSA 6. The Upgrade fails in a vPostgres firstboot error.

VMware Flings are not offical software releases from VMware.
Your support might be obolete by using this Fling.

Workaround for migrating W2k12 vCenter Server 5.5 to vCenter Server Appliance 5.5

24. June 2015 / / 0 Comments

The VMware Labs engineers built a fling to migrate a vCenter Server installed on a Windows Server to the vCenter Server Appliance.

For me the greatest limitation is that Windows Server 2012 a higher isn’t supported yet. Because of “winexe-bug” the migration appliance could not get the data from the source machine. William Lam told me that the engineers know about this issue and hopes that it would be fixed soon.

For all of you who could not wait… maybe I’ve a workaround.
