•If Concatenation List appears, the logical volume is dispersed across parity groups. Select

Concatenation List to view a list of the parity groups.

•If the Concatenation List command does not appear, the logical volume is not dispersed across

parity groups.

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” on page 53 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.

b. Right-click the copy destination port, and select Paste. If a confirmation message appears, click

OK.

NOTE: You cannot paste paths to initiator port.
