Activating the disaster-recovery vfiler

To activate the vfiler in the event of a disaster, perform the following steps.

Step	Action
1	On the destination filer, enter the following command: `vfiler dr activate` source_vfiler `@` source_filer
2	To change the name of the Windows domain controller, use the `cifs prefdc` command.
3	To change the Windows WINS server, run `cifs setup.` Note If the Windows domain has changed, you may need to change the permissions on the Windows data files to allow your users the same access they had in the old domain.
4	Make adjustments on the clients. These include remounting volumes and qtrees.

What activation does

The vfiler dr activate command does the following:

Breaks the SnapMirror relationships between the source and destination filers.
Converts the vfiler into an ordinary vfiler that can be started and that responds to all the commands vfilers support.
Configures IP bindings on the destination vfiler according to the information you provided to the vfiler dr configure command, adding the destination IP information to the destination /etc/rc file. (Any IP information that pertains only to the source vfiler is removed from the destination /etc/rc.)
Configures the NIS and DNS servers according to the information you provided to the vfiler dr configure command.
Configures any quota information saved by the vfiler dr configure command.

Deleting the disaster-recovery vfiler

If you need to delete the disaster-recovery vfiler, you can do so, at any time after you have verified that the configuration process is complete, by running the following command on the destination filer:

vfiler dr delete source_vfiler @ source_filer

This will also remove the SnapMirror relationships, and any other configuration information related to the disaster-recovery vfiler, from the source vfiler.
