Activating the disaster-recovery vFiler unit

Activating the vFiler unit

To activate the disaster-recovery vFiler unit on the destination storage system, perform the following steps.

Step	Action
1	On the destination storage system, 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 might 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, such as remounting volumes and qtrees.

Note
Activating the vFiler unit in the event of a disaster can cause the /etc/hosts.equiv file to be overwritten. If you specified a different set of DNS or NIS servers for the DR location as part of vfiler dr configure command, the existing /etc/hosts.equiv file is overwritten, and the old file is copied to /etc/hosts.equiv.bak. Copy the /etc/hosts.equiv.bak file to /etc/hosts.equiv after entering the vfiler dr activate command.

What activation does

The vfiler dr activate command does the following:

Breaks the SnapMirror relationships between the source and destination storage systems.
Converts the vFiler unit into an ordinary vFiler unit that can be started and that responds to all the commands vFiler units support.
Brings LUNs online.
Configures IP bindings on the destination vFiler unit 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 unit is removed from the destination /etc/rc file.)
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.
