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 an
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, 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 changing 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, enter a UUID composed of a Prefix and an Initial Number. The
Prefix may include up to 5 digits, from 1 to 32767, and the Initial Number may include up
to 5 digits, from 0 to 32767.
For a server host other than OpenVMS, enter a UUID composed of a Prefix and an Initial
Number. The Prefix may include up to 64 ASCII characters (letters, numerals and symbols)
and the Initial Number may include up to 9 digits.
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 182)), then set the proper UUID for a server host.
8. To sequentially number the UUIDs, type the first digit in the Initial Number box. The following
rules apply to the Initial Number:
1: Up to 9 numbers are added (1, 2, 3, ... 9).
08: Up to 92 numbers are added (08, 09, 10, ... 99).
If the host mode is set to OpenVMS, the numbers are as follows:
8, 9, 10, ... 99
23: Up to 77 numbers are added (23, 24, 25, ... 99).
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, then click Apply.
If Go to tasks window for status is checked, the Tasks window opens.
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
The Storage Administrator (Provisioning) role is required to perform this task.
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.
