Configuring FC Host Port
Failover
Scalar i500 User's Guide
• After configuring FC host mapping, save the library configuration.
For instructions on how to save the library configuration, see
and Restoring the Library Configuration
Note: A warning message will display if the command and control
LUN (CCL) or another device is not mapped to LUN 0 (zero).
LUN 0 is typically occupied by the command and control LUN
(CCL), unless it has been manually mapped to another LUN.
Make sure at least one device is mapped to LUN 0.
Note: If an FC switch is attached to an FC I/O blade target port, the
FC switch will appear in the Blade Host Management list as if
it were an FC host. Do not map library devices to an FC switch.
To avoid confusion, it is recommended that you modify the FC
switch host name and type using Blade Host Management. See
Modifying an FC Host Connection
Note: If both channel zoning and host mapping are enabled, the
channel zoning settings supersede any host LUN mapping on
the FC I/O blade. For information on channel zoning, see
Configuring FC I/O Blade Channel Zoning
The paths to open the appropriate screens are as follows:
• From the operator panel, select
• From the Web client, select
When FC I/O blades are installed in the library, administrators can

enable and configure the optional FC host port failover feature. This
feature is disabled by default.
You can configure the FC host port failover feature so that a "standby"
target port (1 or 2) on an I/O blade can assume the identity and LUN
mapping configuration of the designated "active" target port if the active
port fails. Host port failover enables the library to continue operations
without requiring you to reconfigure the host or the SAN.
