Chapter 3: Configuring Your Library
Configuring Fibre Channel Drive Speed, Topology, and Loop ID
Quantum Scalar i6000 User’s Guide

Speed
The requested interface speed can be set to Auto (default;
autonegotiates to highest speed possible), 1 Gb/s, 2 Gb/s, 4 Gb/s, or 8
Gb/s (depending on drive type).
Caution:
LTO-5 and later Fibre Channel tape drives can be
configured for speeds of up to 8 Gb/s. If they are
configured for 8 Gb/s, you should connect them directly to
a host and not to an FC I/O blade, because the FC I/O blade
only allows speeds up to 4 Gb/s. If you connect an LTO-5 or
later Fibre Channel tape drive to an FC I/O blade, you must
configure the tape drive speed of 4 Gb/s or less.
Note:
The speed settings you choose are requested, not actual. If the
requested speed setting is not supported, the next appropriate
setting is negotiated.
Topology
The requested topology connection mode can be set to one of the
following:
• Loop (default) — Force L-Port
• Loop Preferred — Auto-configure trying L-Port first
• Point to Point — Force N-Port
Notes about point to point
• You can use Point to Point if the tape drive is connected via a switch
or directly to a host.
• You cannot use Point to Point if the tape drive is connected to an FC
I/O blade.
• You must use Point to Point if the tape drive is being used for
control path failover (see
