204 Configuring the Library
Configuring Switch Zoning
If one or more FC switches is attached to the library, verify that proper switch zoning is configured.
Proceed to Configuring Switch Zoning
on page 204.
Configuring Host Access
If your host(s) are connected through the management control blade or an FC I/O blade, run FC Host or
SCSI Host, as appropriate, to allow the library to manage your media properly. See Configuring FC Host
LUN Mapping on page 204 or SCSI Host LUN Mapping on page 209.
If you are configuring your LTO-5 drives attached to Ethernet Expansion blades, go to Setting up Control
Path and Storage Networking on page 215.
If your host(s) are directly connected to drives, configure your third-party tape handling software.
FC Host LUN Mapping
During device discovery, a particular partition or drive may map to a higher LUN space than is optimal for a
particular application. The FC Host feature allows you to create a virtual private remapping of available
LUNs for a specific Fibre Channel-attached host. LUN mapping is required to give hosts access to partitions
and devices. You can also make devices appear to the host as if they were at lower LUNs in order to
optimize library performance.
Depending upon host operating system constraints, it may be necessary to reboot or reconfigure the host
as a result of device map changes resulting from the use of FC Host.
Proceed to
Configuring Host Access on page 204.
Once connected, a host will persist in the FC I/O blade memory until it is manually deleted.
Configuring FC Host LUN Mapping
1 Click Setup→ Device→ Access→ FC Host.
The FC Host dialog box appears.
2 Select an FC host to configure.
