132 Library Installation and CRU Replacement
• If the I/O blade is installed in the bottom bay of the expansion module, connect one end of an
Ethernet cable to the Ethernet port labeled
LOWER in the lower right corner of the expansion
module. Connect the other end of the cable to a port in the Ethernet hub on the LCB.
• If the I/O blade is installed in the upper bay of the expansion module, connect one end of an
Ethernet cable to the Ethernet port labeled
UPPER in the lower right corner of the 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.
In addition, 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 appropriate instructions in Adding, Removing, and
Replacing the FC I/O Fan Blade on page 137. 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 Adding, Removing, and
Replacing FC I/O Blades on page 130. If you are installing two FC I/O blades in an expansion module,
install the lower one first.
7 Make sure that 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 Cabling Libraries with Fibre
Channel Tape Drives Connected to Fibre Channel I/O Blades on page 34). See also If you need to add
9U expansion modules to the 5U library control module, remove the module terminator from the 5U
library control module terminator connection that is closest to the 9U expansion module.
on page 38.
9 Configure/reconfigure library partitions if needed (from the Web client, select Setup > Partitions ).
See the User’s Guide for complete instructions.
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. Also, 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
Control Paths and FC I/O Blades
on page 133 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, configure
host mapping so that each host sees each device only once. See the User’s Guide for complete
information and instructions.
To configure host mapping:
CAUTION
If the Ethernet cable between the LCB and EM is not connected when
power is applied to the blade, the blade will hang in the "Booting" state.
