Failover Control Center
From the Failover Control Center, you can manage, monitor, and control failover for your Storage Mirroring servers. The
Failover Control Center displays a main window for monitoring failover activity. Control buttons to the right allow you to
configure and manage your servers.
Configuring communication ports
The Failover Control Center use two ports for various Storage Mirroring communications.
 Service Transmit Port—The Failover Control Center uses this port to send commands to Storage Mirroring servers.
 Heartbeat Listen Port—The Failover Control Center uses this port to listen for heartbeats transmitted from Storage
Mirroring servers.
To view or modify the port settings in the Failover Control Center, select
Settings, Communications.
Configuring refresh rate
The failover client periodically requests information from the source and target. Depending on the type of information, the
request may be a machine-specific request, like obtaining the
Time to Fail status from a target, or may be a general request,
like determining which machines are running Storage Mirroring.
The rate at which these requests are made can be modified through the Failover Control Center refresh rate dialog box.
Select
Settings, Refresh Rate. The default update interval is one second. A lower refresh rate value updates the information
in the Failover Control Center window's
Monitored Machines tree more often, but also generates more network traffic and
higher utilization on the client and target machines. A higher refresh rate value updates the information less frequently, but
minimizes the network traffic.
Clearing maintained security credentials
To remove cached credentials, access the credentials security option, by selecting Settings, Security. To remove the security
credentials, enable
Clear Cached Security Credentials and then click OK.
