30 LUN Manager for the XP10000/XP12000
Defining alternate paths
LUN Manager can define alternate paths. If an LU path fails, you can switch to its alternate path.
To create an alternate path, copy the original path from one port to another. For example, to define an
alternate for the LU path between the CL1-A port and logical volume 00:01, copy the LU path from the
CL1-A port to another port.
If you want to define alternate paths when LUN security is removed, you must redefine the LU path.
Copying paths from one Fibre Channel to another
CAUTION: Before performing the following steps, see ” Restrictions on port operations ” on page 35 for

1. Start LUN Manager, and display the LUN Manager pane ( Figure 7 ).
2. In the LU Path tree, locate the port that you want to use as the copy destination and verify that LUN
