Port 1 Behavior with LME Enabled on Port 2
With Port 2 enabled for LME, Port 1 continues to act as the primary port for the
customer to manage the library sending UI, SNMP, and email alert (SMTP) traffic. In
addition, Port 1 will send SDP-2 traffic. Since the library will only send LME (OKM)
traffic through Port 2, this requires the Oracle Service tool SDP-2 to now be connected
to Port 1 when LME is enabled on Port 2.
Port 2 Behavior with LME Enabled
When Port 2 is configured for LME, the library will send all OKM communication
through Port 2. A service representative can still directly connect to Port 2 for
troubleshooting when the port is configured for LME. However, they must configure
the laptop with a valid IP address on the same subnet as Port 2.
About Tape Drives With Two Ports
When a tape drive has two ports, host applications can treat the second drive port as a
failover port. The library may report a Check Condition to a command received on one
port when the other port is busy with a library command. When a host application
receives either of the following new Check Conditions, it should reissue the command:
Not Ready, Logical Unit Offline (02/04/12h)
■
Aborted Command, Logical Unit Communication Failure (OBh/08/00)

About Bridged Tape Drives
A bridged drive provides a single, unified control and data communication path
between the library/partition and the host using the SAS or FC drive interface. A
non-partitioned library requires one bridged drive. A partitioned library requires one
bridged drive per partition. You select the bridged drive during library configuration
(see
"Configure Library Settings"
Code versions earlier than 2.0 support two partitions, and a maximum of two

bridged drives located in the base module.
Code version 2.01, and later, supports up to eight partitions and bridged drives

located in designated expansion modules.
