• Display the target ID mappings for a Fibre Channel adapter
• Display the current Fibre Channel topology for a Fibre Channel adapter
You have already seen how you can perform these functions from the
command line. The same output is available using the interactive mode by
selecting the appropriate option (shown in the following example).
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 executed to display information will
provide the information for
emx0
.
______________________ Note _______________________
The
emxmgr
has an extensive help facility in the interactive mode.
An example using the
emxmgr
in the interactive mode follows:
# emxmgr
Now issuing commands to : "emx0"
