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. A virtual manager provides disaster recovery
for one of two configurations:
• Configurations with only two storage systems. (A virtual manager will automatically be added
when creating a management group using two storage systems.)
• Configurations in which a management group spans two geographic sites.
See “Managers and quorum” (page 107) for detailed information about quorum, fault tolerance,
and the number of managers.
Because a virtual manager is available to maintain quorum in a management group when a storage
system goes offline, it can also be used for maintaining quorum during maintenance procedures.
CAUTION: A virtual manager requires a manual intervention to recover quorum and can have
undesirable effects when left running after quorum is recovered. That is why HP highly recommends
that you use the Failover Manager rather than the virtual manager.
When to use a virtual manager
Use a virtual manager for disaster recovery in a two-site configuration, or a two-system configuration.
You can also use a virtual manager to maintain quorum during storage system maintenance
procedures, such as firmware upgrades.
