Setting the Topology and the Loop ID (for Direct Server Connections)
The following settings are required for direct server connections:
•
If the Fibre Channel card of the server is an LPe3xxxx series, a PY-FC33x/PY-FC35x series,
an MC-0JFCFx/MC-0JFCGx/MC-0JFCMx/MC-0JFCNx series, or an SP1X7FBC2F
•
If the Fibre Channel card of the server is a series other than the above
For more details about the settings, refer to "FUJITSU Storage ETERNUS LT140 Tape Library User's Guide
-Panel Operation-".
2.2.3
Setting the Topology (for Connections via FC Switches)
The following settings are required for connections via FC switches.
For more details about the settings, refer to "FUJITSU Storage ETERNUS LT140 Tape Library User's Guide -Panel
Operation-".
When connecting the LT140 to a Brocade 16G FC switch (BR65xx/EBRDC8x) with a link speed of 8Gbit/s,
apply firmware version v7.3.0c or later to the FC switch and perform the following settings.
•
FC switch
(1)
For the port to which the LT140 tape drive is connected, fix the speed to 8Gbit/s with the "portcfg-
speed" command.
(2)
For the port to which the LT140 tape drive is connected, disable the DFE function (*1) with the
"portcfgnondfe" command.
*1:
The Decision Feedback Equalization (DFE) function corrects signal noises on the receiver. Disable this
function because it may prevent the port connected to the LTO drive from correctly recognizing the sig-
nal.
•
LT140
(3)
Fix the link speed of the LT140 tape drive to 8Gbit/s.
These settings are not required if the LT140 is connected to a Brocade 32G FC switch (Brocade G610/G620/
G630/X6-4/X6-8) because the LT140 automatically recognizes the link speed.
