Performing Storage Subsystem Operations 184
CAUTION: For the StorageWorks XP1024/XP128 and StorageWorks XP512/XP48 storage subsystems, you
cannot create an LDEV whose size is the same size as the maximum size of free space in an array group
because a control area is also created in the storage subsystem. At least 30 MB of free space must be left
available.
In addition to the listed emulation types, the StorageWorks XP1024/XP128 supports another emulation type
called OPEN-V that enables you to create a logical device whose size is (maximum size of free space - size
required for the control area). The size required for the control area depends on the size of the volume to be
created (maximum of 200 MB).
Table 10-2 shows maximum capacities for standard LU types.
Table 10-2 Maximum Capacities of Standard LU Types
LU Type OPEN-K OPEN-3 OPEN-8 OPEN-9 OPEN-E
Maximum Capacity 1788 MB 2347 MB 7007 MB 7042 MB 13893 MB
NOTE: The XP1024/XP128 and XP512/XP48 storage subsystems may not support the same LU types.
Some LU types are not available on some platforms.
Device Manager uses the following convention for capacity values:
• KB = 1024 bytes
• MB = 1024 KB
• GB = 1024 MB
• TB = 1024 GB
To create a new LDEV:
1. Log in to Device Manager as a system administrator or storage administrator.
2. Select and expand the Subsystems object in the navigation frame, open the physical view for the desired
storage subsystem, and then open the LDEV Information panel for the array group in which you want to
create a new LDEV (see section
10-2-4 ):
• For StorageWorks XP1024/XP128, select Array Groups, select View on the desired frame, select the
desired parity group on the Frame Information (level 1) panel, and then select the desired array group
on the Frame Information (level 2) panel.
• For StorageWorks XP512/XP48, select Array Groups, select View on the desired frame, and then
select the desired array group on the Frame Information panel.
3. On the LDEV Information panel for the desired array group (any tab), select the CREATE LDEV button
(refer to
Figure 10-18 ).
4. For XP1024/XP128 and XP512/XP48, the Create LDEV panel opens (see Figure 10-36 ). Enter the
desired parameters, and then select OK.
• For XP1024/XP128 and XP512/XP48, select the device emulation type, and enter the desired device
size (refer to
Table 10-2 ). The size cannot be larger than the size of the selected device type, except
for OPEN-V (refer to the HP StorageWorks LUN Configuration and Security Manager XP User Guide
for the XP1024/XP128).
5. When the confirmation panel displays (see Figure 10-37 ), select YES to create the LDEV, or select NO to
cancel your request to create the LDEV.
You are notified when the operation is complete and the LDEV ID of the new LDEV is displayed. The new
LDEV is displayed on the LDEV Information panel and is also listed in the Open-Unallocated group for
the storage subsystem (under All Storage or My Storage).
