From the Partner LU alias combo box, specify the alias of the
logical unit (LU) you want to connect to on the remote host. This is
the LU through which the partner TP accesses the network. You do not
have to specify a value in this field if you provide a value in the Fully
Qualified Partner LU Name field.
If you want to clear the value in this field, select the blank entry at the
bottom of the list.
