Defining and viewing alternate paths
Use LUN Manager to define alternate paths. If an LU path fails, you can switch to its alternate path.
To create an alternate path, you must copy the original path from one port to another. For example, to
define an alternative for the LU path from port CL1-A to logical volume 00:01, you must copy the LU
path from port CL1-A to another port.
Copying paths from one Fibre Channel or iSCSI port to another
To use alternate paths, you must copy LU paths from one port to another.
CAUTION:
Before performing the following steps, see Notes on using LUN Manager for important information.
CAUTION:
To define alternate paths when LUN security is disabled, you must redefine the LU path.
1. Start LUN Manager. The LUN Manager pane (Figure 14 or Figure 15) appears.
2. In the tree, double-click the copy source port to display host groups or iSCSI targets below the port.
3. To copy all LU paths defined to a host group, complete the following steps to copy the host group
or iSCSI target:
a. In the tree, right-click the host group, and select Copy. The selected host group or iSCSI target
turns green.
NOTE:
If you right-click a host group or iSCSI target for an initiator port, you cannot copy
paths.
