Failback
1. If you are performing failback before restoring, verify that your source machine is not connected
to the network and that the issue(s) that caused the failure is resolved. If you have already
performed a restoration, your source should already be connected to the network using a unique
identity.
2. Login to the target machine that is currently standing in for the failed source by using the login
command.
NOTE: As noted in the Scripting Guide Introduction on page 1-1, this guide does not explain
Storage Mirroring features and functions, only the scripting aspects of Storage Mirroring.
For details on the different features and functions, see the Storage Mirroring User’s
Guide.
