Perform a cold restore

To perform a cold restore with ontape, the database server must be offline.

You must run the ontape command as the owner of the database server: user informix or root for a standard installation, or the owner of the non-root installation. The owner of the database server for the restore must be the same as the owner of the database server for the backup.

Run the following ontape command to restore all the storage spaces: ontape -r

When you perform a mixed restore, you restore only some of the storage spaces during the cold restore. You must restore at least all the critical dbspaces, as the following example shows:

ontape -r -D rootdbs llogdbs plogdbs
