Configuring managers
After you have set up your management group, cluster, and sites, you may need to change the
manager configuration of your Multi-Site SAN. You also need to add the Failover Manager in all
but one type of configuration.
Overview
The LeftHand OS software automatically starts the regular manager on each storage system when
creating a management group. The number of managers started depends on the number of storage
systems in the group and whether you create a Multi-Site cluster. In some configurations, a Virtual
Manager is also added to the management group. If, however, you plan to use a Failover Manager
instead, you must manually install the Failover Manager on a separate server on the network and
then add it to the management group as required by the design of your Multi-Site SAN. We
recommend using the Failover Manager instead of the Virtual Manager because of its automated
failover/failback capabilities.
Configuring regular managers
After you finish creating the management group, cluster, and sites for your Multi-Site SAN, review
the manager configuration and change it as necessary. See “Common configurations of Multi-Site
SANs” (page 13).
For information about management groups, managers, and starting and stopping managers, see
the chapter “Working with management groups” in the HP StoreVirtual Storage User Guide.
Fault tolerant manager configurations
The LeftHand OS software tracks the configuration of managers to ensure that you have a
fault-tolerant configuration. You may encounter messages with warnings or prerequisites you must
meet before you can change the managers.
For example, if you create a management group and a Multi-Site cluster using two or four storage
systems, the management group has regular managers running on each storage system plus a
Virtual Manager added to the management group. If you want to add a Failover Manager or stop
a manager on one of the storage systems, you must first delete the Virtual Manager from the
management group. Then you can make the other changes.
Installing and configuring a Failover Manager
If you are using a Multi-Site SAN configuration that calls for a Failover Manager, you must install
the Failover Manager from the HP StoreVirtual VSA and Failover Manager DVD onto a separate
server on the network. The Failover Manager can run on VMware ESX Server, VMware Server,
VMware Player, or Microsoft Hyper-V Server. For detailed instructions for installing and configuring
the Failover Manager see the section “Regular managers and specialized managers” in the HP
StoreVirtual Storage User Guide.
