Correspondence table for defining devices

When configuring the storage system, you will need definition information about devices set by

LUN Manager, for example, LUs, LDKC:CU:LDEV, or UUID. A correspondence table similar to the

example below is useful and recommended when collecting this information.

Defining alternate LU paths

You may want to define alternate LU paths so that if one LU path fails, you will be able to switch

to its alternate path.

To create an alternate LU path, copy the original LU path from one port to another. For example,

if you want to define an alternate for the LU path from the CL1-A port to logical volume 00:00:01,

copy the LU path from the CL1-A port to another port.

Use one of these methods to copy LU paths:

• Copy all the LU paths defined in a host group

• Copy one or more (but not all) LU paths defined in a host group

NOTE: Before taking the following steps:

• See “LUN Manager rules, restrictions, and guidelines” (page 129) for important information.

• To define alternate paths when LUN security is disabled, you must redefine the LU path.

Procedure 25 To copy all the LU paths defined in a host group

1. In the Remote Web Console main window, in the Storage Systems tree, select Ports/Host

Groups.

The list of available ports appears in the tree.

2. Select the Host Groups tab, or select a port from the tree and then select the Host Groups tab.

3. Select a host group.

4. Select Create Alternative LUN.

5. In the Create Alternative LUN Paths window, select the copy destination port from the Available

Ports table, and then click Add.

The selected ports appear in the Selected Ports table.

6. Click Finish.

7. In the Confirm window, confirm the settings, in Task Name type a unique name for this task

or accept the default, and then click Apply.

If Go to tasks window for status is checked, the Tasks window opens.

Procedure 26 To copy one or more (but not all) LU paths defined in a host group

1. In the Remote Web Console main window, in the Storage Systems tree, select Ports/Host

Groups.

The list of available ports appears in the tree.

2. In the tree, select a port.

The host groups corresponding to the port appear.

3. In the tree, select a host group.

Information about the selected host group appears on the right side of the window.
