Chapter 3 Configuring Your Library
Working With FC I/O Blades
Scalar i500 User’s Guide

• The two FC target ports (ports 1 and 2) and the four FC initiator ports
(ports 3–6) are displayed in a grid, with the target ports listed in
columns and the initiator ports listed in rows. Check boxes allow you
to associate a target port with an initiator port.
• To permit access, select the check box at the intersection of the
target port and the initiator port. You can associate each initiator
port with more than one target port.
• To restrict access, clear the check box at the intersection of the
target port and the initiator port.
• When you select a check box, the entire FC channel is zoned. This
zoning affects any host application that might be accessing the
I/O blade. If both channel zoning and host mapping are enabled,
the channel zoning settings supersede any host LUN mapping on
the I/O blade.
• After configuring channel zoning, save the library configuration.
For instructions on how to save the library configuration, see
Saving and Restoring the Library Configuration
on page 329.
The paths to open the appropriate screens are as follows:
• From the web client, select
Setup > I/O Blades > Channel Zoning
.
• From the operator panel, select
Setup > I/O Blades > Channel Zoning
.
Managing FC Hosts and
Host Mapping
3
An FC host is the main processing server on a storage area network
(SAN) that receives data and initiates communication with other devices.
When FC I/O blades are installed in the library, administrative users can
access, add, modify, and delete FC hosts and also configure FC host
mapping. Before you can perform any of these FC host management
operations, you need to enable host mapping, which is disabled by
default. See
Enabling/Disabling FC Host Mapping
on page 107.
Note:
This operation should not be performed concurrently by
multiple administrative users logged in from different
locations. You can access the appropriate screens, but you
cannot apply changes while another administrative user is
performing the same operation.
