Configuring failover monitoring and processing
1. Make sure you have a valid source and target specified, click Configure
protection from the main Full-Server Failover Manager page, and then select the
Failover tab.
2. Specify how you want to handle failover monitoring and processing.
l
Manual intervention required—By default, you will be notified when a
failover is necessary, but the failover process will not start until you manually
initiate it. If you disable intervention, failover will automatically start when a
failure is detected.
l
Monitor Interval—By default, the target checks to see if the source is online
every five (5) seconds. The source responds back to the target when it
receives one of these checks. If desired, increase or decrease the interval
between checks.
l
Missed intervals—By default, the target can miss five (5) responses from the
source before assuming the source has failed. If desired, increase or
decrease the number of responses that can be missed before the source is
identified as failed.
Note: Together, the Monitor interval and Missed intervals settings
determine the total time before failover would be triggered. For
example, five missed checks every five seconds would be 25 seconds
to trigger failover. To achieve shorter delays before failover, use lower
values. To achieve longer delays before failover, choose higher
values.
l
Monitor type—Storage Mirroring Recover monitors the source by testing for
a Storage Mirroring Recover network response via ICMP pings or a Storage
Mirroring service response. Select the type of monitoring you want to perform.
l
Pre-Failover Script and Post-Failover Script—If you want to execute a
script on the target before failover (pre-failover) begins or after failover has
occurred (post-failover), specify the path to the script on the target. You can
also search for the script by clicking Browse. The script will be processed
using the same user account that is configured to run the Storage Mirroring
service. Scripts may contain any valid Windows command, executable,
batch, or script file. The Pre-Failover Script will be executed as soon as the
failover process is initiated. The Post-Failover Script will be executed after
the failover process ends and the target has been rebooted.
3. Click OK to save the settings.
