Modifying an FC Host Connection
3
For each FC host connection you want to modify, you can set the
following parameters:
•
Host Name
— the host device name.
•
Host Port
— the host port number.
•
Type
— the appropriate host operating system.
You cannot modify the WWPN. If you want to change the WWPN, you
must delete and re-create the FC host connection.
Deleting an FC Host Connection
3
Administrative users can delete connections to FC hosts without
powering down the system. Before deleting an FC host connection, make
sure the FC host is disconnected (offline) from the I/O blade.
A message will appear if the FC host is online when you attempt to delete
it. To continue, take the FC host offline or disconnect the FC host from the
I/O blade, wait for the FC host to go offline, and then continue to delete
the FC host connection.
The paths to open the appropriate screens are as follows:
• From the operator panel, select
Setup > I/O Blades > Host Management
.
• From the web client, select
Setup > I/O Blades > Host Management
.
Host Mapping - Overview
3
Host mapping enables you to manually modify host information and set
logical unit number (LUN) mappings, and to map specific hosts to library
LUN devices.
I/O blades discover target devices that are attached to ports 3–6, as well
as their internal virtual port (see
FC I/O Blade Internal Virtual Port for
Medium Changers
on page 104). Each of these devices has its own native
logical unit number (LUN) that is used to address the device via the port
Note:
If the host application is connected through an FC switch, a
power cycle of the I/O blade might be required to make the
host go offline. For instructions on how to power cycle an I/O
blade, see
Controlling FC I/O Blade Power
on page 144.
