General Installation
You want to reinstall the Failover Manager. 1. Close your CMC session.
2. In the VI Client, power off the Failover Manager.
3. Right-click and select Delete from Disk.
4. Copy fresh files into the virtual machine folder from the
downloaded zip file or distribution media.
5. Open the VI Client, and begin again.
You cannot find the Failover Manager in the CMC, and
cannot recall its IP address.
• The CMC displays the IP address of a system if it can
be found.
• Open a VI Client session and select the Summary tab
for the system you want. The IP address and DNS name
are displayed in the General information section.

Uninstalling the Failover Manager from VMware vSphere

Using a virtual manager
A virtual manager is a manager that is added to a management group, but is not started on a
storage system until it is needed to regain quorum. The virtual manager functions as an on-demand
manager in a disaster-recovery situation. As an on-demand manager, it can be used to regain
quorum and maintain access to data.
NOTE: If a management group is configured with a virtual manager, an alarm is generated that
cannot be cleared until the virtual manager is removed.
A virtual manager provides disaster recovery for the following configurations:
• Two-system configurations—If you create a management group with only two storage systems
and without a Failover Manager, a virtual manager is automatically added to the management
group. Adding a virtual manager provides the ability to regain quorum if one manager
becomes unavailable.
• Two-site configurations—Using a virtual manager allows one site to continue operating if the
other site fails. The virtual manager provides the ability to regain quorum in the operating site
if one site becomes unavailable, or in one selected site if communication between the sites is
lost. Such capability is necessary if volumes in the management group reside on storage
systems in both locations.
