addresses to fail.
● One Monitored IP Address Fails—Failover begins when any one of the
monitored IP addresses fails. If each IP address is on a different subnet, you
may want to trigger failover after one fails.
13. If Manual Intervention is enabled, Target Data State at Failover will be disabled
because the same options will be presented to you at failover time. If Manual
Intervention is disabled, the options will be enabled so that an option can be
selected to occur automatically when failover occurs. Highlight the source name
and specify the Target Data State at Failover by specifying what data you want to
use on the target when failover occurs.
● Apply Data in Target Queues Then Failover—All of the data in the target
queue will be applied before failover begins. Depending on the amount of
data in queue, the amount of time to apply all of the data could be lengthy.
● Discard Data in Target Queues and Failover Immediately—All of the data
in the target queue will be discarded and failover will begin immediately. Any
data in the target queue will be lost.
● Revert to Last Good Snapshot if Target Data is Bad—If the target data is
in a bad Storage Mirroring Recover state, Storage Mirroring Recover will
automatically revert to the last good Storage Mirroring Recover snapshot
before failover begins. You will lose any data between the last good
snapshot and the failure. If the target data is in a good state, Storage
Mirroring Recover will not revert the target data. Instead, Storage Mirroring
Recover will apply the data in the target queue and then failover. Depending
on the amount of data in queue, the amount of time to apply all of the data
could be lengthy.
14. Highlight the source name and specify the Items to Failover, which identifies
which source components you want to failover to the target.
● IP Addresses—If you want to failover the IP addresses on the source,
enable this option and then specify the addresses that you want to failover.
● Monitored—Only the IP address(es) that are selected for monitoring
will be failed over.
● All—All of the IP address(es) will be failed over.
