Note the following when setting UUID:

• When host mode 05 OpenVMS is used, and if host mode option 33 is set to ON, LUs that do

not have a UUID setting will be inaccessible.

• When host mode 05 OpenVMS is used, and if host mode option 33 is set to OFF, LUs that

have a UUID setting will be inaccessible.

The following rules apply to setting a UUID:

• The following characters cannot be used for UUID: \ / : , ; * ? " < > |

• A space character cannot be used for the first and the last characters of a UUID.

• UUID is case-sensitive. For example, Abc and abc are different UUIDs.

To keep track of device information, create a correspondence table similar to the example in

“Correspondence table for defining devices” (page 143).

Procedure 24 To set a UUID

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

Groups.

The list of available ports appear in the tree.

2. In the tree, select a port.

The host groups corresponding to the port appear in the tree.

3. In the tree, select a host group.

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

4. Select the LUNs tab.

Information about LU paths associated with the selected host group appears.

5. Select one or more logical units to which volumes are assigned (if a volume is assigned to a

LU, the columns on the right of the LUN column are not empty).

When multiple LUs are selected, the same UUID is set to all selected LUs.

6. Click More Actions, and then select Edit UUIDs.

7. In the Edit UUIDs window, in Prefix, type the UUID.

If a UUID is already specified, you can change it. The UUID before change appears in UUID

in the Edit UUIDs window. However, if multiple LUs, or N/As are selected, the Prefix box is

blank.

For an OpenVMS server host, use a numerical value from 1 to 32,767.

For a server host other than OpenVMS, use up to 64 ASCII characters (letters, numerals, and

symbols) for a UUID.

NOTE: When changing the server host OS from HP-UX to Open VMS, or from Open VMS

to HP-UX, the same UUID cannot be used continuously. Clear the UUID setting (see “Clearing

a UUID setting” (page 145)), and then set the proper UUID for a server host.

8. To add the sequential number to UUIDs, type the initial number in the Initial Number box.

9. Click Finish.

10. 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.
