Dual Library Manager Configuration:
For a dual Library Manager configuration, perform the following steps:
1. Wait until the switchover completes and the standby Library Manager has
become the active Library Manager. The switchover takes approximately ten
minutes to complete. The standby Library Manager is the active Library
Manager when its System Status displays the Auto mode, Online state.
2. Call your service representative to repair the failed Library Manager.
The failed Library Manager may recover from the failure and become available
as the standby Library Manager after the database is synchronized.

facility, do not remove the cartridges. Leave the cartridges in place, and the
operation restarts automatically. Cartridges inserted in the convenience I/O
station that remain in the station must be removed from the station, then
reinserted after the Library Manager re-initializes.
