Setting a uuid – HP XP P9500 Storage User Manual

Setting a UUID
You can set an arbitrary ID to identify a logical volume from the host using LUN Manager with
host mode option 33 on. This ID is called the UUID (user-definable LUN identifier).
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 166)
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 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, 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.
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
), 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.
