control path will be filtered out by the I/O blade and will not be
visible to the host. If a Fibre Channel tape drive is currently serving
as the control path for a partition and you plan to connect that tape
drive to an FC I/O blade, you must remove the control path from that
tape drive. To remove the control path from a tape drive:
a Select
Setup > Control Path from the operator panel or the Web
client.
b If you have more than one partition, select the appropriate
partition and click
Next.
c Clear the control path selection on any FC tape drive that you
plan to connect to an FC I/O blade.
5 Add or replace the fan blade(s) following the instructions in Adding,
Removing, and Replacing the FC I/O Fan Blade on page 460. The fan
blade is required to prevent overheating of the FC I/O blade.
6 Add or replace the FC I/O blade(s) following the instructions in
Adding an FC I/O Blade
on page 454 or Replacing an FC I/O Blade
on page 459. If you are installing two FC I/O blades in an expansion
module, install the lower one first.
7 Make sure cover plates are installed over any unused bays in the
expansion module.
8 Connect the library and tape drive cables to the FC I/O blade (see
Figure Figure 48
on page 314). See also Recommended Library
Cabling for FC I/O Blades on page 318.
9 Configure/reconfigure library partitions if needed (from the Web
client, select
Setup > Partitions).
10 Configure control paths if needed. The library assigns control paths
for new partitions when they are created. Ensure that each partition
has only one control path. Ensure that you do not select an FC tape
drive as the control path if it is connected to an FC I/O blade. See
Working With Control Paths
on page 86 for more important
information about control paths. To modify the control path, select
Setup > Control Path from the operator panel or Web client.
11 Configure host mapping (optional). If you have more than one FC
I/O blade in the library, each FC I/O blade will present each
partition that does not have a tape drive as the control path as a target
device to the host. Thus the host may see the same partition multiple
times. To minimize confusion, you should configure host mapping so
