Backing up and restoring from the emulated filer

Emulated filer tape drives inaccessible

You can perform dumps and restores on the emulated filer. However, neither the takeover filer nor the emulated filer can access the tape drives or other peripheral devices on the failed filer.

Prerequisites to performing dumps on an emulated filer

Any dump commands directed to the failed filer's tape drives are executed on the takeover filer's tape drives. Therefore, any dump commands that you execute through the cron command succeed only under the following conditions:

The device names are the same on both filers in the cluster.
The dump commands for the filer and the emulated filer are not scheduled to occur during the same time period; the filer and the emulated filer cannot access the tape drives simultaneously.

Performing dumps on an emulated filer

You can perform dumps on an emulated filer by using the dump command on the takeover filer in partner mode. For information about performing dumps on a filer, see the Data Protection Guide.

Performing restores on an emulated filer

To perform restores on the emulated filer, complete the following steps.

Step	Action
1	Put the restore tape into a drive accessible by the takeover filer.
2	Use the `restore` command in partner mode or as an argument to the `partner` command. Example using the restore command in partner mode: filer1 (takeover)> partner filer1/filer2> restore [options [arguments]] Example using the restore command as an argument to the partner command: filer1 (takeover)> partner restore [options [arguments]]

Step

Action

Put the restore tape into a drive accessible by the takeover filer.

Use the restore command in partner mode or as an argument to the partner command.

Example using the restore command in partner mode:

filer1 (takeover)> partner

filer1/filer2> restore [options [arguments]]

Example using the restore command as an argument to the partner command:
