If you use the interactive mode to modify worldwide name-to-target ID
mapping, you can provide the information interactively or cause the
emxmgr
utility to read a file from which to obtain the mapping data.
When you start the
emxmgr
utility with no command-line options, the
default device used is the first Fibre Channel adapter it finds. If you want
to perform functions for another adapter, you must change the targeted
adapter to the correct adapter. For instance, if
emx0
is present, when you
start the
emxmgr
interactively, any commands that display information will
provide the information for
emx0
.

The
emxmgr
has an extensive help facility in the interactive mode.
An example using the
emxmgr
in the interactive mode to modify worldwide
name-to-target ID mapping follows:
#
emxmgr
Now issuing commands to : "emx0"
Select Option (against "emx0"):
1.
View adapter’s current Topology
2.
View adapter’s Target Id Mappings
3.
Change Target ID Mappings
