If your vCenter Server machine or vCenter Server installation fail permanently, the VSA cluster will continue working, but you cannot manage it from VSA Manager.

If your vCenter Server machine fails, you cannot use VSA Manager to view information about the cluster or perform maintenance tasks.

A hardware component might stop working or a permanent software failure might require that you reinstall your vCenter Server on another computer.

1

Reinstall vCenter Server 5.0 on the same machine or on another machine.

2

Configure the new vCenter Server to use the same IP address and configuration settings as the machine that stopped working.

3

If you make frequent backups of the vCenter Server database, restore the most recent copy.

4

Install VSA Manager on the new vCenter Server machine.

5

Connect with vSphere Client to the reinstalled vCenter Server and select the VSA Manager tab.

6

On the Welcome page of the VSA Installer wizard, select Recover VSA Cluster and click Next.
