If the mirror is performed on the VTL database, the lost configuration information can be recovered. To recover configuration information, do as follows:
Step 1 Right-click a database and choose Mirror > Remove to delete the mirror configuration.
Step 2 Replace the faulty disk. After the disk where the database resides fails, the mirror disk automatically switches to a master disk and the VTL6000 works normally.
Step 3 Right-click a database and choose Mirror > Add to create mirror configuration.
Step 4 Right-click a database and choose Mirror > Synchronize to synchronize configuration information.
Now, system configuration information is recovered.
