Configuring Host
Mapping 3
To configure host mapping, you need to select the partition, tape drive, or
medium changer you want to map and assign a new LUN number for the
device.
Details on configuring host mapping include:
• Host mapping is an optional feature and is disabled by default. For
instructions on how to enable or disable host mapping, see
Enabling/Disabling FC Host Mapping
on page 107.
•The
Setup - Blade Host Mapping screen on the web client lists the host
name, I/O blade location, World Wide Port Name (WWPN), and
operating system type of each available FC host. You can select the
FC host to configure and proceed to the next screen.
The screen lists the available partitions and tape drives connected to
the I/O blade to which the FC host is attached. For each available
partition and tape drive, the screen lists the following:
•
Description — For tape drives: Drive [location
coordinates][(associated partition)]. For partitions: the name
assigned to the partition during the partition creation process.
•
Type — Device type, for example, processor, medium changer
(partition), tape drive.
•
Serial Number — Serial number of the partition or tape drive.
•
Vendor — Device manufacturer.
Note: On the operator panel, the host mapping screens (
Setup > I/O
Blades > Host Mapping
) are not available unless FC host
mapping is enabled. See Enabling/Disabling FC Host
Mapping on page 107.
Note: Depending on host operating system constraints, it might be
necessary to reboot or reconfigure the host due to device
mapping changes that result from configuring host mapping.
