Caution: LTO-5 Fibre Channel tape drives can be configured for
speeds of up to 8 GB per second and support auto-
negotiation to 8 Gb/s, 4 Gb/s, and 2 Gb/s. If they are
configured for 8 Gb/s, you should connect them directly
to a host or switch 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 Fibre Channel tape drive to an FC I/O
blade, the speed will autonegotiate to 4 Gb/s (see Setting
Tape Drive Parameters on page 83). Speeds less than 2
Gb/s are not supported.
Caution: If you enable data path failover, control path failover, or
host access control, do not connect the tape drive to an FC
I/O blade.
Caution: Do not connect a tape drive to both an FC I/O blade and
an Ethernet Expansion blade.
