Chapter 2 Setting the LT260
2.2 Settings for Fibre Channel Connections
When connecting the LT260 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.
• For the FC switch
(1)
For the port to which the LT260 tape drive is connected, fix the speed to 8Gbit/s with the
"portcfgspeed" command.
(2)
For the port to which the LT260 tape drive is connected, disable the DFE function (*1) with the
"portcfgnondfe" command.
*1:
• For the LT260
(3)
Fix the link speed of the LT260 tape drive to 8Gbit/s.
These settings are not required if the LT260 is connected to a Brocade 32G FC switch (Brocade G610/G620/
G630/X6-4/X6-8) because the LT260 automatically recognizes the link speed.
