Managing Failover Through the Text Client
Through the Failover Control Center, the failover process can be configured, monitored, and tested. In addition, the Failover
Control Center can be used to initiate the failback process.
Configuring monitoring and failover
1. If you are using Storage Mirroring replication, establish a source/target connection by following the steps in Establishing a
new connection
on page 6-12.
2. Specify a target machine by using the target command.
3. Determine what NICs are available on the specified target by using the niclist command.
4. Establish a monitor to use with the remaining monitor commands by using the monitor create command.
Command TARGET
Description Identifies a machine as the active target machine
Syntax
TARGET <target_machine>
Options target_machine—Name of the machine
Examples
target jersey
Notes You must be logged into a machine using the login command before using the target
command.
Machine names that contain non-alphanumeric characters must be enclosed in quotation marks.
Command NICLIST
Description Displays the NICs available on the specified target machine. Each NIC is assigned an integer value
and this value is used in the
monitor move command.
Syntax
NICLIST [target_machine]
Options target_machine—Name of the machine
Examples
niclist jersey
Notes If you do not specify a machine name, the value from the current target will be returned. If you
have not identified a target, no data will be returned.
If you have not logged into the target machine, no data will be displayed.
Machine names that contain non-alphanumeric characters must be enclosed in quotation marks.
Command MONITOR CREATE
Description Establishes a source machine as a failover monitor. This is the machine that will be monitored by a
target machine in case it should experience a failure.
