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/A
s 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
), 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).

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.
