minutes. The standby library manager is the active library manager when its
System Status displays Auto/Online mode.
2. Contact the 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.
3. If the failure occurred while inserting cartridges into the high-capacity I/O facility,
do not remove the cartridges. Leave the cartridges in place and the operation
will restart automatically. Cartridges inserted in the Convenience I/O station that
remain in the station will need to be removed from the station and then
re-inserted after the library manager re-initializes.
4. Continue with “BTLS Host Action”.
