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
For information about management groups, managers, and starting and stopping managers, see the
chapter "Working with Management Groups" in the HP StorageWorks P4000 SAN Solution User
Manual.

Fault tolerant manager configurations

The SAN/iQ 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 SAN/iQ Management Software DVD onto a separate server on the
network. The Failover Manager can run on VMware ESX Server, VMware Server, or VMware Player.
For detailed instructions for installing and configuring the Failover Manager see "Using Specialized
Managers" in the HP StorageWorks P4000 SAN Solution User Manual.

Best practice

Install the Failover Manager on a server in a separate physical location from the SAN sites, and then
add it as a separate site in the management group. Doing so will prevent loss of quorum in a site
failure, regardless of which single site fails.
Adding the Failover Manager to the management group and site
Adding the Failover Manager to the management group will likely cause the manager configuration
to become less than optimal. Be sure to change the manager configuration to best reflect the new
configuration of the management group. See the HP StorageWorks P4000 SAN Solution User Manual,
Chapter 9, "Working with Management Groups," the section "Optimum Number of Managers."
1. Use Find to search for the Failover Manager, which appears in the Available Systems pool in
the CMC.
2. Right-click on the Failover Manager and then select Add to Existing Management Group.
If there is more than one management group, select the correct one from the list that opens.
If there is only one management group, the Failover Manager is added to the group.
3. Select the Sites node in the navigation window.
4. Right-click and then select New Site.
5. In the New Site window, type the name and optional description for the Failover Manager site.
6. Click Add in the Site Systems section.
