HP XP External Storage Software - Manual (Page 89)

• VMA
Information about the VMA setting of LUN Security XP Extension. If you mapped the external LU
and previously set the VMA of LUN Security XP Extension, an asterisk (*) appears. If LUN Security
XP Extension is not installed when you remap the volume, you cannot map the volume with the
VMA setting.
• Capacity
External LU's capacity in blocks.
• Characteristic
External LU's identification number.
• Characteristic2
External LU's extended identifying information. This information is used for identifying logical
volumes in the EVA array. For more information, see
Identifying logical volumes of EVA arrays
(using Characteristic 2) .
• ExG (1-16384)
Group number of the connected external LUs. You can specify any decimal value from 1 to 16384.
The E displayed outside the text box is the capital letter of the external LU group.
• Emulation Type
Emulation type of the mapped external LU (from the XP12000/XP10000/SVS200 perspective)
(see
External LU attributes set by mapping ).
If you clear the Except OPEN-V check box, OPEN-V and available mainframe emulation types
appear in the list.
If you select the Except OPEN-V check box, open-system emulation types other than OPEN-V appear
in the list. To map the external LU as an open-system volume, define the emulation type to use for
the mapped LU as OPEN-V or another type. To map the external LU as an open-system volume
using an emulation type other than OPEN-V, select the Except OPEN-V check box.
If you plan to use the mapped external LU for a Flex Copy XP pair, you must select OPEN-V.
When the external LU to be mapped has the VMA setting, you must select OPEN-V.
• LDEV Capacity
Default capacity of the emulation type selected in the Emulation Type box. When the external LU's
capacity is larger than the capacity displayed in LDEV Capacity, the external LU is divided into
the displayed capacity, and multiple LDEVs are created.
• LDEV
Number of LDEVs created at mapping. By default, the maximum number of LDEVs corresponding
to the capacity supported by the emulation type specified in the Emulation Type box appears.
When the external LU to be mapped has the VMA setting, you can select only 1.
• IO Suppression
Mapped external LU's IO Suppression mode (for OPEN-V emulation only) (see
External LU attributes
set by mapping ).
To suppress I/O operations from hosts (by way of the XP12000/XP10000/SVS200) to the mapped
external LU or use the mapped external LU for a Flex Copy pair, select Enable.
If you do not suppress I/O from hosts to the mapped external LU, select Disable (for example, for
use with External Storage XP).
If you set the emulation type to something other than OPEN-V, IO Suppression mode is automatically
set to Disable.
When the external LU to be mapped has the VMA setting, IO Suppression mode is automatically
set to Disable.
