applied to the blade, the blade will hang in the "Booting" state.
• If the FC I/O blade is installed in the bottom bay of the 9U Library Expansion Module, connect one end of an Ethernet
cable to the Ethernet port labeled Lower in the lower right corner of the 9U Library Expansion Module. Connect the
other end of the cable to a port in the Ethernet hub on the LCB.
• If the FC I/O blade is installed in the upper bay of the 9U Library Expansion Module, connect one end of an Ethernet
cable to the Ethernet port labeled Upper in the lower right corner of the 9U Library Expansion Module. Connect the
other end of the cable to a port in the Ethernet hub on the LCB.
4 Remove the control path from tape drives that you plan to connect to an FC I/O blade. You must not allow an FC tape
drive to serve as control path if it is connected to an FC I/O blade. If you do, the 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.
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 appropriate instructions in this sheet. 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 9U Library Expansion Module.
8 Connect the library and tape drive cables to the FC I/O blade (see Figure 9). See also Recommended Library Cabling
for FC I/O Blades.
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 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 that
each host sees each device only once. For more information, see the
Host Mapping - Overview and Configuring Host
Mapping. To configure host mapping:
a From the operator panel or Web client, select Setup > I/O Blades > Blade Control and enable host mapping.
b From the operator panel or Web client, select Setup > I/O Blades > Host Mapping.
12 Configure host port failover on the FC I/O blade (optional). From the Web client, select Setup > I/O Blades > Host
Port Failover. To enable host port failover, you must configure target ports 1 and 2 on the I/O blade as point-to-point
connections (Setup > I/O Blades > Port Configuration). For more information, see
Configuring FC Host Port
Failover.
13 Save the library configuration (see Saving the Library Configuration).
Adding an FC I/O Blade
These instructions explain how to add an FC I/O blade to your library. You can add an FC I/O blade while the library is
powered on.
Required tools: None
1 Access the back of the 9U Library Expansion Module.
Note: The recommended order of installing the FC I/O blade and fan blade in a 9U Library Expansion Module is
starting from the bottom bay and moving up.
2 Remove the cover plate from the appropriate FC I/O blade bay.
3 Press up and out to open the latch hooks on each side of the FC I/O blade.
