8. Once the library begins its power-on sequence, remove the USB device
if necessary.
9. If you imported magazines into empty chambers in a partition’s storage
pool after you generated the backup configuration file, see Restore
Other Configuration Changes on page 380.
10. If necessary, restore the MLM and DLM databases as described in
Restore the MLM and DLM Databases.
Restore the MLM and DLM Databases
Use the following steps to restore the MLM database from a previously
saved backup that was created using the Save MLM Database utility (see
Back Up the MLM and DLM Databases on page 306).
Notes:  Restoring the MLM database also restores the DLM database.
 You can also restore the MLM and DLM databases using an
automatically generated library configuration backup file
(see Restore From an Auto Configuration Save File on
page 377).
1. Use your storage management software to stop all backup or restore
operations on the library.
2. If you plan to restore using an MLM database backup file that was sent
as an email attachment, use the following instructions to copy the file to
a USB device; otherwise, skip to Step 5.
a. Create a folder called SavedMLMDB at the root of a USB device.
b. Copy the xlminfo<date-time>.db or cminfo_<date-time>.zdt
file to the SavedMLMDB folder on the USB device.
3. Log into the library as a user with superuser or administrator
privileges.
4. Stop any PreScan or PostScan operations that are currently running (see
Stop the Discovery Process on page 288 and Pause the PostScan Process
on page 297).
Important
If you do not remove the USB device, the library power-on sequence fails.
If the library fails to boot, power off the library as described in Power Off the Library
on page 157. Once the library is powered off, remove the USB device and power on
the library as described in Power On the Library on page 156.
Caution
The Restore MLM Database from USB utility overwrites the existing MLM and DLM
databases with the versions previously saved on the USB device.
Important
Restoring the MLM and DLM databases requires the library to be idle.
