Performing an External Restore

If you specify the ontape -p -e command in a cold restore, you must restore all storage spaces. Use the ontape -p -e command to restore all or specific storage spaces.

To perform a cold external restore

Shut down the database server.
To shut down the database server, use the onmode -ky command.
To restore the storage spaces from an external backup, use a copy command, such as cp, dd, or tar on UNIX or a file-backup program.
You must restore the storage spaces to the same path as the original data and include all the chunk files.
To perform an external restore of all storage spaces followed by a logical restore, use the following commands:
```
ontape -p -e
ontape -l
```
To perform a physical external restore of specific storage spaces, followed by a logical restore, use these commands:
```
ontape -p -e rootdbs
ontape -p -e critical_space1
ontape -p -e other_dbspaces
ontape -l
```
This step brings the database server to fast-recovery mode. The ontape utility and the database server roll forward the logical logs and bring the storage spaces online.
