Figure 40 Information about LU Paths to be Deleted
Note : If you delete numerous paths at one time, the deletion may take time and the dialog box may
seem to hang temporarily.
Defining and Viewing Alternate Paths
LUN Manager enables you to define alternate paths. If one LU path fails, you can switch to its alternate
path.
To create an alternate path, you need to copy the original path from one port to another. For example, if
you want to define an alternative for the LU path from the CL1-A port to the logical volume 00:00 :01,
you need to copy the LU path from the CL1-A port to another port.
Copying Paths between Fibre Channel Ports
To use alternate paths, you must copy LU paths from one port to another.
Caution : Before taking the following steps, see “ Notes on Using LUN Manager ” on page 19 for
important information.
Caution : To define alternate paths when LUN security is disabled, you must redefine the LU path.
To define alternate paths:
1. Start LUN Manager and display the LUN Manager window ( Figure 4 on page 21).
2. In the tree, double-click the copy source port to display host groups below the port.
3. To copy all the LU paths defined in a host group, take the following steps to copy the host group:
a. Right-click the host group in the tree.
Note : If you right-click a host group for an initiator port, you cannot copy paths.
b. Select Copy from the pop-up menu.
The selected host group turns green.
c. Right-click the copy destination port.
d. Select Paste from the pop-up menu. If a message appears and asks if you want to continue
the operation, click OK.
Note : You cannot paste paths to initiator ports.
To copy one or more (but not all) LU paths defied to a host group, take the following steps:
a. Select the host group from the tree.
b. From the LU Path list on the right, select one or more LUNs to which volumes are assigned. If
a volume is assigned to a LUN, the columns on the right of the LUN column are not empty.
c. Right-click the selection and then select Copy Paths from the pop-up menu.
The selected LUNs turn green.
