Mapping Multiple External Lus At One Time (Add Lu (Auto)); Auto Map Setting Window - HP StorageWorks User Manual

Mapping multiple external LUs at one time (Add LU (Auto))

This section describes the procedure to map multiple external LUs at one time. The procedure starts with the
Add LU (AUTO) command.
When mapping multiple external LUs at one time, the CU:LDEV numbers for the mapped destination
internal XP LDEVs are assigned in a series. When performing the mapping operation, you can select the
first CU:LDEV number for the mapped destination internal XP LDEVs. External Storage XP assigns the
selected CU:LDEV number as the first mapped destination LDEV, and as many subsequent CU:LDEV
numbers are kept for mapping as the number external LUs required to be mapped. To automatically
perform the mapping operation, you can let External Storage XP select the first CU:LDEV number.
NOTE: If you set Interval for the mapping, the CU:LDEV number of the internal XP LDEV that must be
mapped is set to the specified interval value.
CAUTION: If the LUs you are mapping include a volume with the VMA setting, you cannot use the Add LU
(AUTO) command to map them at one time.
Use the Auto Map Setting and Select LDEV windows
time.

• 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 (see
attributes set by
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 a Flex Copy XP 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 External Storage XP.
