In a early stage the symptoms were just application errors especially Java related, and after a few minutes it ends up in a blue screen, after a reboot the sequence started all over again.
Last week I updated a vSphere 4.0 environment at one of our customers, everything went smoothly except after the update we had a issue with the search function within vCenter.
Somehow it wasn’t possible to search a Virtual Machine, but the strange part is that when we searched on other objects like; ESX hosts, datastores, folders etc, they where displayed as normal.
What do you need to do if the VMware vCenter Server or the database will crash or be corrupted and you need to do a disaster recovery to get vCenter Server up and running?
Without a good backup of the vCenter server and its database you’re unable to restore the server and need to reinstall vCenter and configure it from the ground up. Lucky it’s not that hard to create a good disaster recovery plan for backing up vCenter Server and its database. As most of you probable know vCenter is more like a proxy server; that sits between the ESX hosts and the database, almost everything you configure on the vCenter Server is stored in the vCenter database. So it is at most important to create a reliable backup of this database at least once a day.
This morning I saw that VMware has released update 2 of vSphere, so what’s new in vSphere Update 2?
VMware just released vCenter server 2.5 Update 4, with this release comes two new features;
Guest Operating System Customization Improvements
VirtualCenter now supports customization of Windows Server 2008 guest operating systems.
Performance Overview Charts
VirtualCenter 2.5 Update 4 introduces the Performance Overview plug-in, which provides a single view of key performance metrics for CPU, memory, disk, and network without having to navigate through multiple charts. The aggregated charts show high-level summaries of resource distribution.
Well finally you can run vCenter on a Linux OS; it’s been released as a Technology Preview so it’s not supported for production environments.
One big drawback is that it’s required to have some instance of Oracle running.
You can download the appliance from the VMware website located here.
