NOTE:

If you set Interval for the mapping, the CU:LDEV number of the internal LDEV that must

be mapped is set to the specified interval value.

Use the Auto Map Setting and Select LDEV windows (

Figure 49 (page 89)

) for mapping multiple

external LUs at one time.

Figure 48 Auto Map Setting window

ExG (1-16384)

Group number containing the specified external LU. Specify any decimal value from 1 to
16384. The E displayed outside of the text box is the capital letter of the external LU group.

Emulation Type

Emulation type of the external LU from the perspective of the XP12000/XP10000/SVS200
(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
also appear in the list. To map the external LU as an open system LU, decide the mapped LU's
emulation type, either OPEN-V or other than OPEN-V. To map the external LU as an open-system
LU with an emulation type other than OPEN-V, select the Except OPEN-V check box.

If you plan to use the mapped external LU for an XP Flex Copy pair, you must specify OPEN-V.

When the external LU to be mapped has the VMA setting, you must select OPEN-V.

Due to the advantages of the OPEN-V emulation type, HP recommends OPEN-V as the default
type for use with XP External Storage.

Create LDEVs

Number of LDEVs that can be mapped based on the capacity supported by the emulation
type specified in the Emulation Type box. Select the number of LDEVs you want to map from
the Create LDEVs list. The default is Full. When Create LDEVs is Full, the maximum number of
LDEVs that can be created based on the capacity supported by the specified emulation type
are mapped. The total number of LDEVs being mapped appears at Total.

IO Suppression

When you specify the OPEN-V emulation type, you can specify the mapped LU's IO Suppression
mode (see

External LU attributes set by mapping

).

If you 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 an XP Flex Copy pair, select Enable.
