Initiating failback
When failover occurs, a source machine has failed. The steps below must be completed in order to complete failback without
IP address or name conflicts.
1. Verify the source machine is not connected to the network. If it is, disconnect it.
2. Resolve the source machine problem that caused the failure.
3. In the Text Client, login to the target machine that is currently standing in for the failed source by using the login
command.
4. Identify the machine as the target by using the target command.
5. Initiate failback by using the failback command. If you specified a pre-failback script in your failover configuration, that
script will be executed at this time.
When failback is complete, you will be prompted to determine if you want to continue monitoring the source server. Bring
the source back online and then enter
Y or N to indicate if you want to continue monitoring the source machine. After you
have selected whether or not to continue monitoring the source machine, the source post-failback script, if configured, will
be started.
Failback is now complete. If you need to restore newer files from the target to the source, see Restoring Storage Mirroring
Data Through the Text Client on page 12-7.
WARNING: Do not connect the source machine to the network at this time.
Command TARGET
Description Identifies a machine as the active target 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 FAILBACK
Description Initiates the failback process for the specified monitor machine
Syntax FAILBACK < monitor > [ON < target_machine >] [REMONITOR|NOREMONITOR]
Options ‹ monitor —Name of the source machine designated as the monitor
‹ target_machine —Name of the target machine
‹ REMONITOR—Automatically continues monitoring the source machine after failback
‹ NOREMONITOR—Automatically discontinues monitoring the source machine after failback.
Examples failback indy on jersey
Notes ‹ If you do not select remonitor or noremonitor , you will be prompted after failback is
complete to select whether or not to continue monitoring.
‹ Machine names that contain non-alphanumeric characters must be enclosed in quotation marks.
NOTE: At this time, the source machine must be online and Storage Mirroring must be running to ensure that the
source post-failback script can be started. If the source has not completed its boot process, the command
to start the script may be lost and the script will not be initiated.
