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.


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


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


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


Install VSA Manager on the new vCenter Server machine.


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


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


On the VSA Cluster Information page of the VSA Installer wizard, type the required information to recover the existing VSA cluster.



VSA Cluster IP Address

Type the VSA cluster IP address.


If you type a wrong IP address, VSA Manager cannot recover the VSA cluster and shows an error message.

VSA Cluster User Name

Type svaadmin.

VSA Cluster Password

Type the VSA cluster password. The default VSA cluster password is svapass.

Host User Name

Type root.

Host Password

Type the ESXi host password.


On the Verify Information page, review the information that you provided and click Install.


In the confirmation dialog box, click Yes.

The Recovering VSA cluster page appears.


Verify the cluster data after the recovery completes.

The Recover VSA Cluster workflow does not create an HA cluster and does not add the ESXi hosts to it. You can do this manually.


Create a VSA HA cluster and move the hosts to it.


Right-click the datacenter where the VSA cluster is located and select New Cluster.

The New Cluster Wizard opens.


On the Cluster Features page, enter VSA HA cluster in the Name text box.


Select the Turn On vSphere HA checkbox.


Click Next.


On the vSphere HA page, configure the HA cluster options and click Next.
